Abstract
The Ca2+-dependent enzyme peptidyl-arginine deiminase type III (PAD3) catalyses the deimination of arginine residues to form citrulline residues in proteins such as keratin, filaggrin and trichohyalin. This is an important post-translation modification that is required for normal hair and skin formation in follicles and keratocytes. The structure of apo human PAD3 was determined by X-ray crystallography to a resolution of 2.8 Å. The structure of PAD3 revealed a similar overall architecture to other PAD isoforms: the N-terminal and middle domains of PAD3 show sequence and structural variety, whereas the sequence and structure of the C-terminal catalytic domain is highly conserved. Structural analysis indicates that PAD3 is a dimer in solution, as is also the case for the PAD2 and PAD4 isoforms but not the PAD1 isoform.

Abstract
Calcium is an important early signal in wound healing, yet how these early signals promote regeneration remains unclear. Peptidylarginine deiminases (PADs), a family of calcium-dependent enzymes, catalyze citrullination, a post-translational modification that alters protein function and has been implicated in autoimmune diseases. We generated a mutation in the single zebrafish ancestral pad gene, padi2, that results in a loss of detectable calcium-dependent citrullination. The mutants exhibit impaired resolution of inflammation and regeneration after caudal fin transection. We identified a new subpopulation of cells displaying citrullinated histones within the notochord bead following tissue injury. Citrullination of histones in this region was absent, and wound-induced proliferation was perturbed in Padi2-deficient larvae. Taken together, our results show that Padi2 is required for the citrullination of histones within a group of cells in the notochord bead and for promoting wound-induced proliferation required for efficient regeneration. These findings identify Padi2 as a potential intermediary between early calcium signaling and subsequent tissue regeneration.

Abstract
Peptidylarginine deiminase (PAD) enzymes are of enormous interest in biomedicine. They catalyze the conversion of a positively-charged guanidinium at an arginine side chain into a neutral ureido group. As a result of this conversion, proteins acquire the non-ribosomally encoded amino acid "citrulline". This imposes critical influences on the structure and function of the target molecules. In multiple sclerosis, myelin hyper-citrullination promotes demyelination by reducing its compaction and triggers auto-antibody production. Immune responses to citrulline-containing proteins play a central role in the pathogenesis of autoimmune diseases. Moreover, auto-antibodies, specific to citrullinated proteins, such as collagen type I and II and filaggrin, are early detectable in rheumatoid arthritis, serving as diagnostic markers of the disease. Despite their significance, little is understood about the role in demyelinating disorders, diversified cancers, and auto-immune diseases. To impart their biological and pathological effects, it is crucial to better understand the reaction mechanism, kinetic properties, substrate selection, and specificities of peptidylarginine deiminase isoforms.Many aspects of PAD biochemistry and physiology have been ignored in past, but, herein is presented a comprehensive survey to improve our current understandings of the underlying mechanism and regulation of PAD enzymes.

Abstract
Multiple sclerosis is a complex human neurodegenerative disease, characterized by the active destruction of the insulating myelin sheath around the axons in the central nervous system. The physical deterioration of myelin is mediated by hyperdeimination of myelin basic and other proteins, catalysed by the Ca2+-dependent enzyme peptidylarginine deiminase 2 (PAD2). Thus, inhibition of PAD2 may be of value in treatment of this disease. Here, we have first characterized the in vitro kinetic properties of the human peptidylarginine deiminase isoform 2 (hPAD2). Phosphatidylserine and phosphatidylcholine reduced its Ca2+ dependence by almost twofold. Second, we have explored the putative inhibitory action of the methyl ester side chain of paclitaxel (TSME), which shares structural features with a synthetic PAD substrate, viz., the benzoyl-l-arginine ethyl ester (BAEE). Using the known crystallographic structure of the homologous enzyme hPAD4 and in silico molecular docking, we have shown that TSME interacted strongly with the catalytic site, albeit with a 100-fold lower affinity than BAEE. Despite paclitaxel having previously been shown to inhibit hPAD2 in vitro, the side chain of paclitaxel alone did not inhibit this enzyme’s activity.

Abstract
Peptidylarginine deiminases (PADs), which are a group of posttranslational modification enzymes, are involved in protein citrullination (deimination) by the conversion of peptidylarginine to peptidylcitrulline in a calcium concentration-dependent manner. Among the PADs, PAD2 is widely distributed in various tissues and is the only type that is expressed in brain. To elucidate the involvement of protein citrullination by PAD2 in the pathogenesis of brain-specific prion diseases, we examined the profiles of citrullinated proteins using the brains of scrapie-infected mice as a prion disease model. We found that, compared with controls, increased levels of citrullinated proteins of various molecular weights were detected in different brain sections of scrapie-infected mice. In support of this data, expression levels of PAD2 protein as well as its enzyme activity were significantly increased in brain sections of scrapie-infected mice, including hippocampus, brain stem, and striatum. Additionally, the expression levels of PAD2 mRNA were increased during scrapie infection. Moreover, PAD2 immunoreactivity was increased in scrapie-infected brains, with staining detected primarily in reactive astrocytes. Using two-dimensional electrophoresis and matrix-assisted laser desorption/ionization-time of flight mass spectrometry, various citrullinated proteins were identified in the brains of scrapie-infected mice, including glial fibrillary acidic protein, myelin basic protein, enolases, and aldolases. This study suggests that accumulated citrullinated proteins and abnormal activation of PAD2 may function in the pathogenesis of prion diseases and serve as potential therapeutic targets.

Abstract
Members of the family of peptidylarginine deiminases (PADs, EC 3.5.3.15) catalyze the posttranslational modification of peptidylarginine into peptidylcitrulline. Citrulline-containing epitopes have been shown to be major and specific targets of autoantibodies produced by rheumatoid arthritis patients. Recently, the citrullination of histone proteins by PAD enzyme was reported to influence gene expression levels. These findings greatly increase the interest in the PAD enzymes and their activities. A few procedures to monitor PAD activity in biological samples have been described previously. However, these assays either have low sensitivity or are rather laborious. Here we describe a reliable and reproducible method for the determination of PAD activity in both purified and crude samples. The method is based on the quantification of PAD-dependent citrullination of peptides, immobilized in microtiter plates, using antibodies that are exclusively reactive with the reaction product(s). Our results demonstrate that this antibody-based assay for PAD activity, called ABAP, is very sensitive and can be applied to monitor PAD activity in biological samples.

Abstract
Deimination corresponds to the transformation of arginine residues within a peptide sequence into citrulline residues. Catalyzed by peptidylarginine deiminases, it decreases the net positive charge of proteins, alters intra and intermolecular ionic interactions and probably the folding of target proteins. Deimination has recently been implicated in several physiological and pathological processes. Here, we describe the enzymes involved in this post-translational modification, focusing on their expression, location and roles in skin, as well as their known protein substrates in the epidermis and hair follicles. We discuss also the potential involvement of deimination in human diseases including cutaneous disorders.

Abstract
Myelin basic protein (MBP) binds to negatively charged lipids on the cytosolic surface of oligodendrocyte membranes and is responsible for adhesion of these surfaces in the multilayered myelin sheath. The pattern of extensive post-translational modifications of MBP is dynamic during normal central nervous system (CNS) development and during myelin degeneration in multiple sclerosis (MS), affecting its interactions with the myelin membranes and with other molecules. In particular, the degree of deimination (or citrullination) of MBP is correlated with the severity of MS, and may represent a primary defect that precedes neurodegeneration due to autoimmune attack. That the degree of MBP deimination is also high in early CNS development indicates that this modification plays major physiological roles in myelin assembly. In this review, we describe the structural and functional consequences of MBP deimination in healthy and diseased myelin.

Abstract
Posttranslational modifications are chemical changes to proteins that take place after synthesis. One such modification, peptidylarginine to peptidylcitrulline conversion, catalysed by peptidylarginine deiminases, has recently received significant interest in biomedicine. Introduction of citrulline dramatically changes the structure and function of proteins. It has been implicated in several physiological and pathological processes. Physiological processes include epithelial terminal differentiation, gene expression regulation, and apoptosis. Rheumatoid arthritis, multiple sclerosis, and Alzheimer's disease are examples of human diseases where protein citrullination involvement has been demonstrated. In this review, we discuss our current understanding on the importance of protein deimination in these processes. We describe the enzymes catalyzing the reaction, as well as their known protein substrates. We review the citrullinated peptide epitopes that are proposed as disease markers, specifically recognized in certain human autoimmune disorders. The potential autopathogenic role of citrullinated epitopes is also discussed.

Abstract
Peptidylarginine deiminases (PAD) convert protein-bound arginine residues into citrulline residues in a Ca(2+) ion-dependent manner. Among the five isoforms (PAD1, 2, 3, 4, and 6) existing in rodents and humans, PAD2 is the most widely expressed in both species, tissues, and organs. In order to study the mechanisms regulating the expression of the human PAD2 gene, PADI2, we characterized its promoter region using transfected human keratinocytes. A series of reporter gene constructions derived from the 2 kb region upstream of the transcription initiation site defined a minimal promoter sequence from nucleotides -132 to -41. This PADI2 region is GC-rich and lacks canonical TATA and CAAT boxes. Investigation of cis-acting elements in the region, further deletion analyses and electrophoretic mobility shift assays using specific antibodies revealed four Sp1-binding sites and identified Sp1 and Sp3 as binding factors important for the promoter activity. These results suggest that Sp1/Sp3 cooperation may provide a mechanism to control the transcription of PADI2.

Abstract
Citrullinated proteins are the products of a posttranslational process in which arginine residues undergo modification into citrulline residues when catalyzed by peptidylarginine deiminases (PADs) in a calcium ion-dependent manner. In our previous report, PAD2 expressed mainly in the rat cerebrum became activated early in the neurodegenerative process. To elucidate the involvement of protein citrullination in human neuronal degeneration, we examined whether citrullinated proteins are produced during Alzheimer's disease (AD). By Western blot analysis with antimodified citrulline antibody, citrullinated proteins of varied molecular weights were detected in hippocampal tissues from patients with AD but not normal humans. Two of the citrullinated proteins were identified as vimentin and glial fibrillary acidic protein (GFAP) by using two-dimensional gel electrophoresis and MALDI-TOF mass spectrometry. Interestingly, PAD2 was detected in hippocampal extracts from AD and normal brains, but the amount of PAD2 in the AD tissue was markedly greater. Histochemical analysis revealed citrullinated proteins throughout the hippocampus, especially in the dentate gyrus and stratum radiatum of CA1 and CA2 areas. However, no citrullinated proteins were detected in the normal hippocampus. PAD2 immunoreactivity was also ubiquitous throughout both the AD and the normal hippocampal areas. PAD2 enrichment coincided well with citrullinated protein positivity. Double immunofluorescence staining revealed that citrullinated protein- and PAD2-positive cells also coincided with GFAP-positive cells, but not all GFAP-positive cells were positive for PAD2. As with GFAP, which is an astrocyte-specific marker protein, PAD2 is distributed mainly in astrocytes. These collective results, the abnormal accumulation of citrullinated proteins and abnormal activation of PAD2 in hippocampi of patients with AD, strongly suggest that PAD has an important role in the onset and progression of AD and that citrullinated proteins may become a useful marker for human neurodegenerative diseases.

Abstract
Rheumatoid arthritis (RA) is a common, systemic autoimmune disease of which the exact etiology is not known. In the past 10 years, substantial progress has been made in the identification of the antigens specifically recognized by the autoantibodies of RA patients. A central factor in this respect is citrullination, a form of post-translational modification that is strongly associated with autoimmunity in RA. Here, we summarize and discuss our current knowledge on (i) autoantibody systems in RA, (ii) the occurrence of peptidylarginine deiminases and (iii) citrullinated proteins in natural and diseased environments, and (iv) genetic factors involved in RA that may influence the generation and presentation of citrullinated proteins and the resulting antibody production against these modified proteins. Citrullination of proteins may play a key role in the initiation and/or the progression of RA. The onset of citrulline-specific autoimmunity in RA is probably mediated by both environmental and genetic factors, and future studies will learn whether therapeutic intervention at the level of citrullination may provide new possibilities to treat RA.

Abstract
OBJECTIVE Antibodies to citrulline-containing epitopes of filaggrin are highly specific for rheumatoid arthritis (RA). We studied whether the enzyme peptidylarginine deiminase (PAD), responsible for the post-translational modification of peptide-bound arginine residues to citrulline, constitutes an antigen for patients with RA. METHODS IgG antibodies to PAD were measured by enzyme-linked immunosorbent assay (ELISA) in sera from patients with RA, systemic lupus erythematosus (SLE), primary Sjögren syndrome (pSS), multiple sclerosis (MS) and healthy controls. RESULTS Compared to healthy controls, raised levels of IgG antibodies to PAD were found in 50 of 57 recent-onset RA patients (88%) and in 40 (70%) of the same 57 patients 3 years later (p<0.0001 for both comparisons). Eleven of 51 (22%) patients with RA of long duration, 19/43 (44%) patients with SLE and 16/19 (84%) patients with pSS, but none of 20 patients with MS, had elevated anti-PAD levels. CONCLUSION The arginine-citrulline converting enzyme PAD was recognized as a new antigen against which patients with inflammatory rheumatic diseases frequently show IgG class antibodies.

Abstract
Peptidylarginine deiminase (PAD, EC 3.5.3.15) enzymes catalyze the conversion of protein-bound arginine to citrulline. This post-translational modification may have a big impact on the structure and function of the target protein. In this review, we will discuss the effects of citrullination and its involvement in several human diseases, including rheumatoid arthritis and multiple sclerosis. So far, four isotypes of PAD have been described in mammals. We describe the existence of PAD in non-mammalian vertebrates and the existence of a fifth mammalian PAD. In addition, tissue-specific expression, genomic organization and evolutionary conservation of the different PAD isotypes will be discussed in detail. This article contains supplementary material which may be viewed at the BioEssays website at http://www.interscience.wiley.com/jpages/0265-9247/suppmat/2003/25/v25.1106.html.

Abstract
In this study, we demonstrate that grossly unaffected white matter from secondary progressive multiple sclerosis (SP-MS) patients is heavily citrullinated, as compared to normal white matter from control patients. Citrullination was most pronounced at plaque interfaces and was shown to colocalize with glial fibrillary acidic protein (GFAP)-immunoreactivity using dual color immunofluorescence. In contrast, the plaques themselves weakly stained for citrullinated proteins compared to control white matter and usually contained a blood vessel with surrounding astrocytes that were positive both for citrullinated proteins and GFAP. In SP-MS brain samples, but not in normal brains, long fibers of colocalized GFAP- and citrullinated proteins extended into the gray matter. Increased numbers of astrocytes containing citrullinated proteins and GFAP were also present at the junction between the gray and white matter in SP-MS brains. Western blot analysis of acidic brain proteins from nonplaque-containing white matter showed upregulation of multiple citrullinated GFAP proteins in SP-MS brains as compared to controls. Our results demonstrate that increased amounts of citrullinated GFAP are present in SP-MS brains, but also shows that these proteins are present in areas of MS brains that were grossly normal appearing. These data raise the possibility that citrullination of GFAP contributes to the pathophysiology of MS.

Abstract
By using hybridoma technology, an IgM monoclonal antibody (F95) against multiple citrullinated synthetic and natural peptides was recently developed and used to stain immunohistochemically subsets of astrocytes and myelin basic protein (MBP) from selected regions of human brain (Nicholas and Whitaker [2002] Glia 37:328-336). With this antibody, the present study provides a more detailed localization of citrullinated epitopes in the central nervous system (CNS) by examining immunohistochemical staining patterns for F95 in the normal adult rat brain. Thus, immunohistochemical labeling for citrullinated epitopes was seen in white matter areas consistent with myelin staining; however, in general, it was more prominent and uniform in the caudal CNS (spinal cord, medulla oblongata, pons, and cerebellum) than in more rostral areas. F95 staining was also seen in cells and fibers often intimately associated with blood vessels and/or ventricular surfaces. By using dual-color immunofluorescence, the vast majority of this latter staining was colocalized within a subset of astrocytes also immunoreactive for glial fibrillary acidic protein (GFAP). By using Western blot analysis of rat brain proteins, multiple GFAP- and MBP-immunoreactive proteins and peptide fragments were seen, and many of them were also reactive with the F95 antibody. Thus, the present study not only demonstrates that citrullinated epitopes in normal rat brain are most concentrated in subsets of myelin and astrocytes but also provides evidence that GFAP, like MBP, may be present as multiple citrullinated isoforms.

Abstract
Peptidylarginine deiminases (PADs) catalyse a post-translational modification of proteins through the conversion of arginine residues into citrullines. The existence of four isoforms of PAD (types I, II, III and IV) encoded by four different genes, which are distinct in their substrate specificities and tissue-specific expression, was reported in rodents. In the present study, starting from epidermis polyadenylated RNA, we cloned by reverse transcriptase-PCR a full-length cDNA encoding human PAD type I. The cDNA was 2711 bp in length and encoded a 663-amino-acid sequence. The predicted protein shares 75% identity with the rat PAD type I sequence, but displays only 50-57% identity with the three other known human isoforms. We have described the organization of the human PAD type I gene on chromosome 1p36. A recombinant PAD type I was produced in Escherichia coli and shown to be enzymically active. Human PAD type I mRNAs were detected by reverse transcriptase-PCR not only in the epidermis, but also in various organs, including prostate, testis, placenta, spleen and thymus. In human epidermis extracts analysed by Western blotting, PAD type I was detected as a 70 kDa polypeptide, in agreement with its predicted molecular mass. As shown by immunohistochemistry, the enzyme was expressed in all the living layers of human epidermis, with the labelling being increased in the granular layer. This is the first description of the human PAD type I gene and the first demonstration of its expression in epidermis.

Abstract
Peptidylarginine deiminases (PADs) are posttranslational modification enzymes that convert protein arginine to citrulline residues in a calcium ion-dependent manner. Rodents have four isoforms of PAD (types I, II, III, and IV), each of which is distinct in substrate and tissue specificity. In fact, the only tissue in which all four PAD mRNAs have been detected is the epidermis. In this study, we found PAD activity in HSC-1 human cutaneous squamous carcinoma cells in vitro, and this activity increased during cultivation. Using a homology-based strategy, we cloned a full-length cDNA encoding human PAD type II. The cDNA was 2348 bp long and encoded a 665-amino-acid sequence with a predicted molecular mass of 75 kDa. The predicted protein shared 93% identity with the rat and mouse PAD type II sequence. Alignment of the amino acid sequences from both species revealed notable conservation in the C-terminal region, suggesting the presence of a functional region such as an enzyme catalytic site and/or a calcium-binding domain. Gene organization analysis established that human PAD type II on chromosome 1p35.2-p35.21 spanned more than 50 kb and contained 16 exons and 15 introns. A recombinant PAD protein subsequently produced in Escherichia coli proved to be enzymatically active, with substrate specificities similar to those of the rat PAD type II. In an immunohistochemical study of human skin, the type II enzyme was expressed by all the living epidermal layers, suggesting that PAD type II is functionally important during terminal differentiation of epidermal keratinocytes.

Abstract
In earlier studies we demonstrated that an increase in the relative amounts of citrullinated myelin basic protein (MBP) was found in multiple sclerosis (Moscarello et al. 1994). To determine the temporal relationship between the citrullinated MBP and peptidylarginine deiminase (PAD), the enzyme responsible for deiminating arginyl residues in proteins, we studied enzyme activity, enzyme protein, PAD mRNA in a spontaneously demyelinating transgenic mouse model and we correlated the amount of PAD with citrullinated MBP. Both PAD protein as measured in an immunoslot blot method and PAD RNA were elevated. In fractionation studies we showed that the increase in PAD enzyme was due to an increase in the PAD found in membrane fractions and not the soluble PAD (PADII). From our data we concluded that up-regulation of myelin-associated PAD was responsible for the increase in citrullinated MBP in our transgenic mice prior to onset of clinical or pathological signs of demyelination. We postulate that a similar mechanism may be responsible for the increase in citrullinated MBP in multiple sclerosis.

Abstract
Peptidylarginine deiminase catalyzes the post-translational modification of proteins through the conversion of arginine to citrulline in the presence of calcium ions. In rodents, peptidylarginine deiminase has been classified into four isoforms, types I, II, III, and IV, which are distinct in their molecular weights, substrate specificities, and tissue localization. Of these isoforms, only type III was detected in epidermis and hair follicles. Although the role of this enzyme in these tissues is not yet clear, indirect data have shown that several structural proteins such as filaggrin, trichohyalin, and keratin are substrates for peptidylarginine deiminase. In this study, we cloned the full-length cDNA of human peptidylarginine deiminase type III (3142 bp) from cultured human keratinocytes by reverse transcription-polymerase chain reaction and by rapid amplification of cDNA ends methods. This cDNA contained a 1995 bp open reading frame encoding 664 amino acids (Mr = 74 770). To explore the physicochemical and enzymatic properties of human peptidylarginine deiminase type III, we constructed a plasmid for producing a recombinant human peptidylarginine deiminase type III in bacteria. The enzymatic characteristics of the recombinant enzyme were very similar to those of the rodent peptidylarginine deiminase type III. The recombinant enzyme showed the catalytic activities toward structural proteins of epidermis and hair follicle, filaggrin and trichohyalin, in which the deiminations maxima of about 60% and 13% arginine residues were observed in filaggrin and trichohyalin, respectively. An immunohistochemical study of human scalp skin with a monospecific anti-peptidyl-arginine deiminase type III antibody revealed that the type III enzyme was localized to the inner root sheath and outer root sheath of hair follicles. Peptidylarginine deiminase type III in the inner root sheath was notable between supramatrix and keratogenous zone and was scarcely detected in cornified hair zone. The enzyme was also expressed in the cuticle layer of hair. On the other hand, expression of the enzyme in the epidermis was very low. These data imply that human peptidylarginine deiminase type III is the predominant isoform in hair follicles and may function as a modulator of hair structural proteins, including trichohyalin during hair and hair follicle formation.

Abstract
The activity of peptidylarginine deiminase (PAD) has generally been assayed by a colorimetric method using N-benzoyl-L-arginine ethyl ester (BAEE) and N-benzoyl-L-arginine (Bz-L-Arg) as the substrates. The widespread occurrence of citrulline and urea in tissues makes use of this method difficult, especially for small samples. We developed a highly sensitive high-performance liquid chromatography method with N-dansyl-glycyl-L-arginine as the substrate. This method was sensitive enough to determine previously undetectable activity of PAD in HL-60 cells. Two types of PAD (HL-60 cell and brain PAD) could be distinguished by differential competition, using either BAEE or Bz-L-Arg as a preferential substrate in the assay. These data indicate that the present method is applicable to many tissues.

Abstract
Three types of peptidylarginine deiminase (PAD), which converts a protein arginine residue to a citrulline residue, are widely distributed in animal tissues. Little is known about PAD of hemopoietic cells. We found that PAD activity in human myeloid leukemia HL-60 cells was induced with the granulocyte-inducing agents retinoic acid and dimethyl sulfoxide and with the monocyte-inducing agent 1alpha,25-dihydroxyvitamin D(3). We cloned and characterized a PAD cDNA from retinoic acid-induced cells. The cDNA was 2,238 base pairs long and encoded a 663-amino acid polypeptide. The HL-60 PAD had 50-55% amino acid sequence identities with the three known enzymes and 73% identity with the recently cloned keratinocyte PAD. The recombinant enzyme differs in kinetic properties from the known enzymes. Immunoblotting and Northern blotting with an antiserum against the enzyme and the cDNA, respectively, showed that a protein of approximately 67 kDa increased concomitantly with increase of mRNA of approximately 2.6 kilobases during granulocyte differentiation. During monocyte differentiation the same mRNA and protein increased as in granulocyte differentiation. Neither the enzyme activity nor the protein was found in macrophage-induced cells. These results suggested that expression of the PAD gene is tightly linked to myeloid differentiation.

Abstract
We have measured the expression and activity of peptidylarginine deiminase (PAD, EC 3.5.3.15), the enzyme responsible for converting arginyl residues in proteins to citrullines, in normal mouse brain homogenate. PAD transcripts were detected as early as five days and were maximal at one month of age. The enzyme protein was also detected at 5 days in an antibody dependent assay and was maximal at 2 months of age, 1 month later than the maximum expression of transcripts. As expected, enzyme activity had a similar developmental profile to that of the enzyme protein. In isolated mouse brain compact myelin, the activity was highest at 15 days and fell rapidly to 15% of this level by 1-2 months. In the 'loose' myelin fraction (heavy myelin) it remained at the same high level form from 15 days to 8 months. The activity in compact myelin was about 15 times greater than the activity in brain homogenate, suggesting much of the enzyme was localized to myelin.

Abstract
Peptidylarginine deiminases (PADs), a group of post-translational enzymes, catalyze the conversion of protein-bound arginine residues to citrulline residues in a calcium ion-dependent manner and are widely distributed in various organs of vertebrates. Although the existence of four isoforms of PAD (types I, II, III, and IV) is reported in rodents, the relative functions of the isoforms with respect to their colocation in the tissues have yet to be explored. In this study, we cloned the full-length cDNA encoding mouse PAD type I by screening a uterine cDNA library and using the RACE method. This cDNA consists of an open reading frame of 1989 bases encoding 662 amino acids (73,823 Da), a 5'-untranslated region of 127 bases and a 3'-untranslated region of 1639 bases. Comparative reverse transcription-PCR and Northern-blot analyses detected PAD type I mRNA only in the epidermis and uterus. Administration of estrogen to adult ovariectomized mice increased the content of PAD type I mRNA in the uterus, providing evidence that its expression is under the control of the sex steroid hormone. We also cloned the full-length cDNAs of mouse PAD type III and type IV by the reverse transcription-PCR and RACE methods. The primary structure of PAD type III contains 664 amino acids (75,098 Da) deduced from the coding region of 1995 bases, and the primary structure of PAD type IV consists of 666 amino acids (74,475 Da) deduced from the coding region of 2001 bases. Comparison of the deduced amino acid sequences of all four isoforms of PAD showed about 50% identity with each other, the 3' regions being highly homologous compared with the 5' regions.

Abstract
A method is described for the direct colorimetric determination of citrulline residues in proteins based on the reaction with diacetylmonoxime in the presence of lower concentrations of sulfuric acid. The reduced sensitivity due to the lower acid concentration was overcome by the addition of ferric chloride which also contributed to the color stabilization. Insoluble proteins or proteins resulting in turbidity can be analyzed following partial hydrolysis of those with enzyme or acid. The molar absorption coefficient (epsilon) for citrulline at 464 nm was 2.8 x 10(4). The method enabled us to determine low levels of protein-bound citrulline which are beyond the limitations of conventional methods using an amino acid analyzer. We determined the citrulline contents in the cornified cells of the epidermis of newborn rats, as well as soybean trypsin inhibitor.

Although the principal effect of paclitaxel (taxol) is in preventing depolymerization of microtubules, other effects have been described recently. In the present manuscript, we demonstrate an inhibitory effect on the enzyme peptidylarginine deiminase (PAD) which converts peptidyl bound arginine to citrulline. To study the mechanism of action of the drug on PAD, a number of studies were carried out with purified enzyme. With the synthetic substrate benzoyl-arginine ethyl ester (BAEE), almost total inhibition of activity was observed at 12. 5 mM. With myelin basic protein (MBP) as a substrate, deimination of arginyl residues was prevented by 0.5 mM paclitaxel. The velocity-substrate curve was unusual since substrate enhancement was observed at 5 mM BAEE. These data suggested the presence of two binding sites on the enzyme. Inhibition of activity by paclitaxel was non-competitive for both sites.

Abstract
Peptidylarginine deiminases (PADs) are a group of enzymes which convert protein arginine residues to citrulline residues. Using rat muscle PAD cDNA as a probe, we obtained two novel cDNAs, PAD-R11 and PAD-R4, from immortalized rat keratinocytes treated with all-trans retinoic acid. Comparison of the deduced amino acid sequences with those of muscle and hair follicle enzymes showed high conservation in the C-terminal region. Recombinant proteins encoded by both PAD-R11 and PAD-R4 showed the enzyme activities. That of PAD-R11 showed a characteristic feature of the enzyme found in the epidermis.

Abstract
The enzyme peptidylarginine deiminase (PAD; EC 3.5.3.15) is responsible for the formation of protein-bound citrulline, a major amino acid in the inner root sheath (IRS) and in the medulla of the hair follicle. From mainly biochemical evidence, it is known that the substrate for the enzyme is trichohyalin and that trichohyalin granules gradually disappear to form a matrix with intermediate-like filaments in the IRS cells. In the medulla, the granules aggregate into large masses without filaments. The proteins in both the IRS and medulla are finally cross-linked by transglutaminase. A corollary of the apparent central role of PAD acting on the trichohyalin protein in these processes is that it should be present in the IRS and medulla cells, coincident with trichohyalin. Hair-follicle PAD has not previously been isolated. In the current study, the enzyme was isolated from wool follicles of adult sheep and peptide sequences were used to design DNA primers for the synthesis of PCR products from follicle mRNA. Subsequently, a PAD-specific complementary RNA probe and a trichohyalin complementary RNA probe were prepared for localization studies by in situ hybridization in wool follicles and the epithelia of the rumen, embryonic hoof, and tongue papillae. The experiments have revealed a striking co-expression of PAD and trichohyalin in all of these tissues. The amino acid sequence of the wool-follicle PAD molecule has been deduced from sequencing of the cloned PCR products.

Abstract
Peptidylarginine deiminases, which are commonly found in mammalian cells, catalyze the deimination of protein-bound arginine residues to citrullines. However, very little is known about their substrate requirements and the significance or consequences of this postsynthetic modification. We have explored this reaction in vitro with two known substrates filaggrin and trichohyalin. First, the degree and rate of modification of arginines to citrullines directly correlates with the structural order of the substrate. In filaggrin, which has little structural order, the reaction proceeded rapidly to >95% completion. However, in the highly alpha-helical protein trichohyalin, the reaction proceeded slowly to about 25% and could be forced to a maximum of about 65%. Second, the rate and degree of modification depends on the sequence location of the target arginines. Third, we show by gel electrophoresis, circular dichroism, and fluorescence spectroscopy that the reaction interferes with organized protein structure: the net formation of >/=10% citrulline results in protein denaturation. Cyanate modification of the lysines in model alpha-helix-rich proteins to homocitrullines also results in loss of organized structure. These data suggest that the ureido group on the citrulline formed by the peptidylarginine deiminase enzyme modification functions to unfold proteins due to decrease in net charge, loss of potential ionic bonds, and interference with H bonds.

Abstract
Peptidylarginine deiminase is localized in the cytosol of the luminal and glandular epithelia of the nonpregnant murine uterus and its expression is regulated by sex hormones [Takahara et al., [1989]: J Biol Chem 264, 13361-13368; Takahara et al. [1992]: J Biol Chem 267,520-525]. Here, we demonstrate that changes occur in the enzyme level in the mouse uterus during pregnancy and parturition. After a rapid decrease in enzymatic activity from day 1 to day 5 of pregnancy, the activity sharply increased during the middle stage of pregnancy (day 8 to day 10) and then gradually decreased during late pregnancy. Expression of the enzyme occurred only in the decidual cells that had differentiated from endometrial stroma cells surrounding the implantation site. The immunochemical properties of the enzyme expressed in the decidualized cells was indistinguishable from those in the uterine epithelia. These results suggest that peptidylarginine deiminase has important roles in decidual cells and not just in the epithelia of the nonpregnant uterus. Moreover, the level of enzyme activity increased slightly just before parturition (day 17), and then decreased during the 12 h period after parturition. The tissue localization of the enzyme expressed around the time of parturition changed from decidua to the luminal and glandular epithelia. Semiquantitative analyses of the enzyme mRNA content in the pregnant uteri showed a remarkable increase from day 7 leading to the onset of the enzyme synthesis in the decidual cells. After reaching the maximal level at day 12, small peaks in the mRNA level were observed at two times during late pregnancy. Since these serial changes in the mRNA level did not correlate with changes in sex hormones, the expression of decidual peptidylarginine deiminase seemed to be controlled by factors other than sex hormones.

Abstract
A peptidylarginine deiminase (PAD; EC 3.5.3.15) has been isolated from bovine brain and some of its characteristics have been studied. The enzyme showed an absolute requirement for Ca2+, a temperature optimum at approximately 50 degrees C, and two Km values when benzoylarginine ethyl ester was used as substrate, 0.78 mM and 11.2 mM. The higher Km has not been reported previously. Protein substrates for the enzyme included polyarginine and myelin basic protein but not histones. Because one of the components of MBP contains six citrullinyl residues per mole, enzymic deimination appeared to be a likely mechanism. When the most cationic component (C-1) was subjected to PAD in solution, 17 of the 19 arginyl residues were modified. From sequence analyses we concluded that the nature of the amino acid residues adjacent to the deiminated arginine were not modifiers of the reaction as arginyl residues in a variety of environments were deiminated. This deimination was reflected in a large increase in random structure, as measured by [theta]200. At 5 degrees C, the [theta]200 of the deiminated protein was -70 x 10(3) compared with -30 x 10(3) deg.cm2/dmol for the native protein. When the temperature was increased to 70 degrees C, the [theta]200 was -44 x 10(3) for the deiminated protein and -20 x 10(7) deg.cm2/dmol for the native C-1. When plotted as a function of temperature, [theta]200 decreased linearly from 5 degrees C to 50 degrees C for both proteins and did not change from 50 degrees C to 70 degrees C. PAD provides a mechanism for deimination of arginyl residues of myelin basic protein. The selective deimination of the six arginyl residues that are consistently found deiminated in C-8 may be determined by the orientation of the protein in the membrane and/or the more complex lipid composition of myelin may affect the selectivity of the deimination.

Abstract
Peptidylarginine deiminase is a protein-modulating enzyme which converts the arginine residues in proteins to citrulline residues. This study describes the complete primary structure of mouse peptidylarginine deiminase, which was deduced from nucleotide sequence analysis of cDNA clones plus proteochemical analysis of the purified enzyme. The composite cDNA sequence contained a 5' untranslated region of 7 bases, an open reading frame of 2019 bases that encoded 673 amino acids, a 3' untranslated region of 2662 bases, and part of a poly(A) tail. The N-terminal and C-terminal sequences of the enzyme matched the sequences deduced from nucleotide analysis. Furthermore, we determined that the N-terminal sequence was N alpha-acetyl-Met-Gln-, a sequence which has never previously been reported among N alpha-acetyl-Met proteins. The Arg 352 of the enzyme was converted to a citrulline residue and the potential Asn-linked glycosylation site (Asn542-Glu543-Ser544) had no carbohydrate moiety. Thus, mouse peptidylarginine deiminase consists of 673 amino acids with a molecular mass of 76,260. Mouse peptidylarginine deiminase mRNA has two AU-rich structures in the 3' untranslated region which exhibit a high degree of similarity to those in lymphokine, cytokine and proto-oncogene mRNA species. Since the rat enzyme (previously reported) does not possess these characteristic structures, we compared the levels of enzyme activity and mRNA in the mouse and rat uterus at four defined phases of the estrous cycle. The degradation of peptidylarginine deiminase and its mRNA proceeded significantly faster in the mouse than in the rat. We speculate that the unusual structure of the mouse enzyme and its mRNA be involved in this species-specific rapid degradation.

Abstract
We have developed a new detection method of deiminated proteins on polyvinylidene difluoride membranes. Citrulline residues in enzymatically deiminated histones were modified by incubating with diacetyl monoxime and antipyrine in a strong acid mixture. The products were injected to rabbits, and the antibodies obtained were affinity-purified using a modified citrulline column. Sample proteins blotted to the membrane were modified in a similar manner and incubated successively with the purified antibody and an alkaline phosphatase-conjugated second antibody. Detection was performed using a chemiluminescent substrate. The method enabled detection of 3-10 fmol of citrulline residues dot blotted as deiminated model proteins. It visualized numerous rat pituitary soluble proteins that had been enzymatically deiminated and Western blotted to the membrane. The data suggest usefulness of the method for detecting deiminated proteins regardless of the backbone protein molecules. Search for deiminated proteins on the Western blots of various rat tissue homogenates detected a single band on that of spinal cord, another band on that of uterus, and multiple bands on those of skin and hair root. The bands in the former two tissue homogenates comigrated with glial fibrillary acidic protein and vimentin, respectively.

Abstract
The enzyme peptidylarginine deiminase is responsible for the post-translational modification of certain proteins by catalysing the deimination of arginine residues to citrullines. Recently, peptidylarginine deiminase has been purified from rat skeletal muscle and its primary structure determined by molecular cloning. We have used antibodies raised against this enzyme to examine its distribution in the rat central nervous system. A few discrete neuronal cell groups in the telencephalon were selectively stained. These were the septofimbrial nucleus, the anterior commissural nucleus of the hypothalamus, and the anterodorsal thalamic nucleus. The subcommissural organ was intensely stained; but other circumventricular organs were not. In addition, peptidylarginine deiminase-immunoreactivity was found in a large population of small cells throughout the grey and white matter of the rat brain. Some of these cells contained glial fibrillary acidic protein and could thus be identified as astrocytes. However, in many regions these peptidylarginine deiminase-positive cells appeared distinct from the glial fibrillary acidic protein-positive astrocytes. Light and electron microscopic examination indicated that these cells had the morphology of microglia, however they were not stained by a lectin marker for microglia. These cells often surrounded cerebral capillaries, and sent ramifying processes into the neuropil. Peptidylarginine deiminase has been suggested to be involved in the synthesis of the endothelium-derived relaxing factor nitric oxide from arginine-containing molecules. Thus the distinct peptidylarginine deiminase-positive glial cells surrounding cerebral blood vessels may be in a position to regulate local blood flow in response to neuronal activity.

Abstract
Insulin and type I insulin-like growth factor (IGF-I) suppressed growth hormone (GH) expression followed by the induction of prolactin (PRL) biosynthesis in MtT/S cells cultured with normal sera. Insulin also increased the peptidylarginine deiminase activity in a dose-dependent manner. The increase was detectable at 1 ng/ml and reached a maximum (about 16-fold higher than the control) at 1 micrograms/ml. IGF-I showed similar but less prominent effects. The enzyme activity started to increase by 15 hr after the addition of insulin (500 ng/ml), and reached a plateau level at 48 hr. There were concurrent increases in the enzyme mRNA level, enzyme biosynthesis, and enzyme protein contents detected by Northern blot hybridization, [35S]-amino-acid incorporation, and Western immunoblot analysis, respectively. Two-color immunofluorescence staining at 1 day after the insulin addition detected a small number of peptidylarginine-deiminase-positive cells (about 1% of the total cells) which were also GH-positive. The enzyme-positive cells increased to 12% on day 2 and to 24-26% on days 4-6. PRL-positive cells first appeared in the enzyme-positive cell population on day 2, and PRL-positive, enzyme-negative cells appeared later. These results suggest that peptidylarginine deiminase expression increases in association with the hormone switching in MtT/S cells. When the cells were cultured in a steroid-depleted medium, insulin failed to increase the enzyme activity. The insulin action could be specifically restored by estrogen, indicating estrogen-insulin synergism in regulation of the enzyme expression.

Abstract
A Nonidet P-40 extract of growth hormone-producing rat pituitary MtT/S cells was found to contain peptidylarginine deiminase (EC 3.5.3.15), which was indistinguishable from an enzyme preparation from rat muscle in Western immunoblotting and immunoprecipitation. This enzyme was immunocytochemically detected in the cytoplasm but was not secreted into the medium during the cultivation. When the cells were cultured for 2 days with various concentrations of 17 beta-estradiol (E2), the enzyme activity increased in a dose-dependent manner, reaching a maximum level (four- to fivefold higher than control) at about 10(-9) M. This increase in the enzyme activity was evident by 14 hr of culture and became relatively stable after 24 hr. It correlated well with the increase in the amount of the muscle type enzyme per cell as analyzed by Western immunoblotting. Estriol and a synthetic estrogen, diethylstilbestrol, also increased the enzyme activity, whereas testosterone, progesterone, and corticosterone were without effect. An antiestrogen, tamoxifen, which by itself was inactive, partially suppressed the effect of E2. Exposure of MtT/S cells for 14 hr to E2 increased incorporation of 35S-labeled amino acids into the immunoprecipitable peptidylarginine deiminase. This increase was dependent on the concentration of E2, attaining a maximum level (about tenfold higher than the control) at about 10(-9) M. These results indicate that estrogen effects the increase in peptidylarginine deiminase content in the pituitary cells by stimulating enzyme synthesis.

Abstract
Northern blot hybridization demonstrated 4.5-5.0 kilobase peptidylarginine deiminase mRNA in poly (A)+ RNA-enriched fractions of both male and female pituitaries. Dot blot analysis of total RNA fractions showed more than 50-fold sex difference in the mRNA content. The female pituitary mRNA content showed at least a 50-fold variation during the estrous cycle characterized by elevation at diestrus and proestrus followed by a rapid decline at estrus. The data were discussed in comparison with the sex difference and estrous cycle dependence of the pituitary enzyme content reported previously.

Abstract
We have performed a combined biochemical and immunochemical study on the identity of peptidylarginine deiminases (EC 3.5.3.15) present in various mammalian tissues. First, we purified peptidylarginine deiminase from rat skeletal muscle. It gave a single band of molecular weight 83,000 in sodium dodecyl sulfate polyacrylamide gel electrophoresis. Next we immunized rabbits with the purified enzyme. The resulting antibodies reacted specifically with the antigen in Western blot assay. Most of the enzyme activities present in rat skeletal muscle, brain, spinal cord, submaxillary gland and spleen could be characterized as the same muscle-type enzyme by immunoprecipitation and Western blot assay. The antibodies did not react with enzyme samples obtained from rat hair follicles and bovine epidermis. The lack of immunoreactivity of the epidermal enzyme could not be accounted for by the species difference, since the antibodies reacted with a 83 kDa polypeptide of bovine brain, which was thought to represent a bovine counterpart of the muscle-type enzyme. The epidermal enzyme could be distinguished from the other enzyme samples by its high activity towards benzoylarginine. These data suggest the existence of at least three types of peptidylarginine deiminase in mammalian tissues, i.e., a muscle type, a hair follicle type, and an epidermal type.

Peptidylarginine deiminase activity has been found in some tissues from at least one representative of each vertebrate class, suggesting that the occurrence of the enzyme throughout the vertebrates is widespread. Using a three-step procedure including affinity chromatography on arginine agarose, a greatly improved purification of bovine epidermal peptidylarginine deiminase is presented. The purified enzyme preparation contains a 70-75 kD band and several minor components when examined by sodium dodecyl sulfate electrophoresis. A polyclonal antibody raised to the enzyme of bovine brain cross-reacts with human and newborn rat epidermis by indirect immunofluorescence. This cross-reactivity is markedly diminished by absorption of the antibody to the purified brain enzyme.
