The M-CSF receptor in osteoclasts and beyond. Exp Mol Med 2020; 52:1239-1254.

Abstract
Colony-stimulating factor 1 receptor (CSF1R, also known as c-FMS) is a receptor tyrosine kinase. Macrophage colony-stimulating factor (M-CSF) and IL-34 are ligands of CSF1R. CSF1R-mediated signaling is crucial for the survival, function, proliferation, and differentiation of myeloid lineage cells, including osteoclasts, monocytes/macrophages, microglia, Langerhans cells in the skin, and Paneth cells in the intestine. CSF1R also plays an important role in oocytes and trophoblastic cells in the female reproductive tract and in the maintenance and maturation of neural progenitor cells. Given that CSF1R is expressed in a wide range of myeloid cells, altered CSF1R signaling is implicated in inflammatory, neoplastic, and neurodegenerative diseases. Inhibiting CSF1R signaling through an inhibitory anti-CSF1R antibody or small molecule inhibitors that target the kinase activity of CSF1R has thus been a promising therapeutic strategy for those diseases. In this review, we cover the recent progress in our understanding of the various roles of CSF1R in osteoclasts and other myeloid cells, highlighting the therapeutic applications of CSF1R inhibitors in disease conditions. Drugs directed at a key signaling receptor involved in breaking down bone tissue could help treat diseases marked by pathological bone loss and destruction. In a review article, Kyung-Hyun Park-Min and colleagues from the Hospital for Special Surgery in New York, USA, discuss the essential roles played by the colony-stimulating factor 1 receptor (CSF1R) protein in the survival, function, proliferation and differentiation of myeloid lineage stem cells in the bone marrow, including bone-resorbing osteoclasts. They explore the links between the CSF1R-mediated signaling pathway and diseases such as cancer and neurodegeneration. The authors largely focus on bone conditions, highlighting mouse studies in which CSF1R-blocking drugs were shown to ameliorate bone loss and inflammatory symptoms in models of arthritis, osteoporosis and metastatic cancer. Clinical trials are ongoing to test therapeutic applications.

Transcriptional mechanisms that control expression of the macrophage colony-stimulating factor receptor locus. Clin Sci (Lond) 2017; 131:2161-2182. [DOI: 10.1042/cs20170238] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2017] [Revised: 05/22/2017] [Accepted: 06/11/2017] [Indexed: 12/17/2022]
Abstract
The proliferation, differentiation, and survival of cells of the macrophage lineage depends upon signals from the macrophage colony-stimulating factor (CSF) receptor (CSF1R). CSF1R is expressed by embryonic macrophages and induced early in adult hematopoiesis, upon commitment of multipotent progenitors to the myeloid lineage. Transcriptional activation of CSF1R requires interaction between members of the E26 transformation-specific family of transcription factors (Ets) (notably PU.1), C/EBP, RUNX, AP-1/ATF, interferon regulatory factor (IRF), STAT, KLF, REL, FUS/TLS (fused in sarcoma/ranslocated in liposarcoma) families, and conserved regulatory elements within the mouse and human CSF1R locus. One element, the Fms-intronic regulatory element (FIRE), within intron 2, is conserved functionally across all the amniotes. Lineage commitment in multipotent progenitors also requires down-regulation of specific transcription factors such as MYB, FLI1, basic leucine zipper transcriptional factor ATF-like (BATF3), GATA-1, and PAX5 that contribute to differentiation of alternative lineages and repress CSF1R transcription. Many of these transcription factors regulate each other, interact at the protein level, and are themselves downstream targets of CSF1R signaling. Control of CSF1R transcription involves feed–forward and feedback signaling in which CSF1R is both a target and a participant; and dysregulation of CSF1R expression and/or function is associated with numerous pathological conditions. In this review, we describe the regulatory network behind CSF1R expression during differentiation and development of cells of the mononuclear phagocyte system.

Abstract
The CSF-1 receptor (CSF-1R) is activated by the homodimeric growth factors colony-stimulating factor-1 (CSF-1) and interleukin-34 (IL-34). It plays important roles in development and in innate immunity by regulating the development of most tissue macrophages and osteoclasts, of Langerhans cells of the skin, of Paneth cells of the small intestine, and of brain microglia. It also regulates the differentiation of neural progenitor cells and controls functions of oocytes and trophoblastic cells in the female reproductive tract. Owing to this broad tissue expression pattern, it plays a central role in neoplastic, inflammatory, and neurological diseases. In this review we summarize the evolution, structure, and regulation of expression of the CSF-1R gene. We discuss the structures of CSF-1, IL-34, and the CSF-1R and the mechanism of ligand binding to and activation of the receptor. We further describe the pathways regulating macrophage survival, proliferation, differentiation, and chemotaxis downstream from the CSF-1R.

Abstract
Expression of calcium channel alpha1 subunits in oocytes or cell lines has proven to be a powerful method in the analysis of structure-function relations, but these experimental systems are of limited value in the examination of neuron-specific functions such as transmitter release. Cell lines derived from neurons are often capable of these functions, but their intrinsic calcium channel alpha1 subunits are complicating factors in experimental design. We have examined the biophysical and molecular properties of calcium channels in a little studied neuroblastoma-glioma hybrid cell line, 140-3, a close relative of the NG108-15 cell line, to test whether this cell line might serve a role as an expression system for neural mechanisms. This cell was selected as it contains an intact transmitter release mechanism yet secretes little in response to depolarization. Patch-clamp recording revealed only a prominent low-threshold, rapidly inactivating calcium current with a single-channel conductance of approximately 7 pS that was identified as T type. A search for calcium channel alpha1 subunit messenger RNA in the 140-3 cells with three different tests only revealed alpha1C, whereas alpha1A-alpha1C were present in the parent NG108-15 line. We made a particular effort to search for alpha1E, since this subunit has been associated with a low-voltage-activated current. Our findings suggest that, since the principal nerve terminal-associated calcium channels (alpha1A, alpha1B, alpha1E) are absent in the 140-3 cell, this cell line may prove a particularly useful model for the analysis of the role of high-voltage-activated calcium channels in complex functions of neuronal cells.

Abstract
Mammalian voltage-gated K channel genes have been divided into four subfamilies (Shaker, Shab, Shal, and Shaw) based on their sequence identity and similarity to related genes in Drosophila. Genetic mapping of the voltage-gated K channel genes has shown that similar multigene clusters exist on mouse Chr 3 and 6 and suggests that the clusters may have arisen through chromosomal duplication. In this report, YAC-based physical maps of the clustered mouse Shaker-like K channel genes have been constructed using restriction endonuclease and yeast chromosome fragmentation approaches. These data define the physical spacing as 5'-Kcna3-(60 kb)-Kcna2-(90 kb)-Kcna8-3' on Chr 3, and as 5'-Kcna6-(80 kb)-Kcna1-(110 kb)-Kcna5-3' on Chr 6, with all genes oriented in a head-to-tail manner within their respective clusters. These detailed physical maps of both K channel gene clusters provide additional support for the idea of an ancient genome tetraploidization event.

Abstract
Productive infection with HIV-1, the virus responsible for AIDS, requires the involvement of host cell factors for completion of the replicative cycle, but the identification of these factors and elucidation of their specific functions has been difficult. A human cDNA, TRBP, was recently cloned and characterized as a positive regulator of gene expression that binds to the TAR region of the HIV-1 genome. Here we demonstrate that this factor is encoded by a gene, TARBP2, that maps to human chromosome 12 and mouse chromosome 15, and we also identify and map one human pseudogene (TARBP2P) and two mouse TRBP-related sequences (Tarbp2-rs1, Tarbp2-rs2). The map location of the expressed gene identifies it as a candidate for the previously identified factor encoded on human chromosome 12 that has been shown to be important for expression of HIV-1 genes. Western blotting indicates that despite high sequence conservation in human and mouse, the TARBP2 protein differs in apparent size in primate and rodent cells.

Abstract
The mouse autosomal recessive mutant gene weaver (wv) results in abnormalities in cerebellum, substantia nigra and testis. Although a substracted cDNA library prepared by removing P31 (wv/wv) sequences from a P1 (wv/+) library should contain mainly nonrepetitive neonatal sequences, unfortunately, repetitive sequences still appear during screening. Two clones, one repetitive, the other not, are used to illustrate the problems encountered in attempting to isolate the weaver gene from a substrated cDNA library.

Abstract
From a mouse genomic library we isolated and characterized a gene, Fabph1, encoding mammary-derived growth inhibitor (MDGI)/heart fatty-acid-binding protein (H-FABP). Exon sequences were identical with a MDGI-encoding cDNA isolated previously from the mammary gland of pregnant mice. The product of this gene has also been detected in heart, where it had been termed H-FABP. It has an intron/exon structure similar to other FABP-encoding genes. In addition to this expressed gene, we isolated a related intronless pseudogene, Fabph-ps, with an open reading frame which was highly conserved when compared with Fabph1. Fabph1 was positioned on chromosome (Chr) 4 using interrelated sequence locus, Fabph-rs1, to Chr 8. A Mus spretus-specific related sequence, Fabph-rs2, was identified on Chr 17 by analysis of interspecies crosses. The 5'-flanking region of Fabph1 contains putative transcription factor-binding elements which could account for its constitutive expression in muscle tissue, as well as for its developmental stage-dependent expression in mammary epithelium.

Abstract
We have isolated and characterized the gene encoding mouse synexin, which consists of 14 exons and spans approximately 30 kbp of genomic DNA. The protein's unique N-terminal domain is encoded by six exons, and the C-terminal tetrad repeat, the site of the membrane-fusion and ion-channel domain, is encoded by seven exons. The first exon encodes the 5'-untranslated region. Analysis of synexin-gene expression in different mouse tissues shows that mRNA with exon 6 is only present in brain, heart and skeletal muscle. mRNA lacking exon 6 is expressed in all tissues we have examined. The initiation site for transcription was determined by primer-extension analysis and S1 nuclease mapping. Sequence analysis of the 1.3 kb 5'-flanking region revealed that the promoter has a TATA box located at position -25 and a number of potential promoter and regulatory elements. A CCAAT motif was not observed but CCATT is located in an appropriate position for the CCAAT motif upstream from the transcription-initiation start site. In addition, the 5'-flanking region contains two sets of palindromic sequences. Finally, we have determined that the functional synexin gene (Anx7) is located on mouse chromosome 14 and that a pseudogene (Anx7-ps1) is located on chromosome 10.

Abstract
The immunopathogenesis of autoimmune insulin-dependent diabetes in NOD mice entails defects in the development of macrophages (M phi s) from hematopoietic precursors. The present study analyzes the cellular and molecular basis underlying our previous finding that the Mø growth factor colony-stimulating factor 1 (CSF-1) promotes a reduced level of promonocyte proliferation and M phi development from NOD bone marrow. CSF-1 stimulation of NOD marrow induced Møs to differentiate to the point that they secreted levels of tumor necrosis factor alpha equivalent to that of controls. However, CSF-1 failed to prime NOD M phi s to completely differentiate in response to gamma-interferon, as shown by their decreased lipopolysaccharide-stimulated interleukin 1 secretion. These defects, in turn, were associated with an inability of CSF-1 to up-regulate c-fms (CSF-1 receptor) and Ifgr (gamma-interferon receptor) expression. Even though the combination of CSF-1 and gamma-interferon up-regulated c-fms and Ifgr transcript levels in NOD M phi s to levels induced in control M phi s by CSF-1 alone, the protein kinase C activities coupled to these receptors remained 4-fold lower in NOD M phi s than in M phi s derived from the marrow of diabetes-resistant NON and SWR control mice. Despite expressing the diabetogenic H-2g7 haplotype, M phi s derived from cytokine-stimulated marrow of the NON.H-2g7 congenic stock were functionally more mature than similarly derived M phi s from NOD mice. Whereas diabetes resistance was abrogated in 67% of irradiated (NOD x NON)F1 females reconstituted with NOD marrow, no recipients became diabetic after reconstitution with a 1:1 mixture of marrow from NOD and the congenic stock. Thus, failure to develop functionally mature monocytes may be of pathogenic significance in NOD mice.

Abstract
The nondefective Moloney murine leukemia virus (MuLV) induces clonal or oligoclonal T-cell tumors in mice or rats. The proviruses of these nondefective MuLVs have been shown to act as insertion mutagens most frequently activating an adjacent cellular gene involved in cell growth control. Mutations by provirus insertions, recognized as common provirus integration sites, have been instrumental in identifying novel cellular genes involved in tumor formation. We have searched for new common provirus integration sites in Moloney MuLV-induced thymomas. Using cellular sequences flanking a provirus cloned from one of these tumors, we found one region, designated Mis-2, which was the target of provirus integration in a low (3%) percentage of these tumors. Mis-2 was mapped on mouse chromosome 10, approximately 160 kbp downstream of myb. The Mis-2 region may contain a novel gene involved in tumor development.

Abstract
In conclusion, using concatenated AhRE sequences and the recognition site probe methodology, we have cloned the murine Hmg1 cDNA and determined an additional 141 bp of 5' noncoding sequence (GenBank Accession No. S50213; entry name MUSHMG1A). The gene product represents an HMG-box transcription factor that recognizes DNA shape- and sequence-specific elements; this is perhaps the reason that this cDNA was isolated with concatomeric oligonucleotides. We have mapped the Hmg1 gene to mouse Chr 2, between regions homologous with human Chr 2q and 11p11-q12.

Abstract
The cytokine termed hepatocyte growth factor or scatter factor (HGF/SF) has been implicated in embryonic development and liver regeneration. Mouse HGF/SF cDNA clones were obtained by screening a mouse liver cDNA library with synthetic oligonucleotides, as well as by using the method of reverse transcription-polymerase chain reaction (RT-PCR) with mRNA isolated from adult mouse brain. Sequence analysis of mouse HGF/SF cDNA clones spanning the entire coding region revealed an overall amino acid identity of 90% and 98% with human and rat HGF, respectively. Using mouse HGF antisense RNA as a probe, we observed the expression of HGF/SF mRNA in the liver, kidney, whole brain and cerebellum of adult mice as well as in day 9 and day 10 mouse embryos. The mouse HGF/SF cDNA was utilized for mapping Hgf to the centromeric region of mouse Chromosome 5 in apparent close proximity to the reeler mutation by the analysis of two multilocus crosses. The relationship of Hgf to the reeler mutation is discussed. The availability of mouse HGF/SF cDNA clones should facilitate further analysis of HGF/SF function during development.

Abstract
A beta 1-adrenergic receptor (beta 1AR) clone, designated Clone 5, was isolated from a BALB/c mouse liver genomic library screened at low stringency with a human brain beta 2 AR cDNA probe. Sequence analysis of Clone 5 revealed a 1,395-bp open reading frame encoding a 464-amino-acid polypeptide. The predicted protein exhibited structural features characteristic of members of the G-protein-coupled receptor family including seven hydrophobic segments corresponding to putative transmembrane domains, a potential N-linked glycosylation site near the amino-terminus, and multiple potential phosphorylation sites in the third cytoplasmic loop and carboxy-terminal cytoplasmic tail. The sequence of the Clone 5-encoded protein was nearly identical to those previously reported for the rat and human beta 1 ARs. Potentially important differences were noted in the third cytoplasmic loop and carboxy-terminal cytoplasmic tail. Reverse transcription-primer extension studies of adult mouse brain RNA demonstrated the predominant transcriptional start site to be 415 nucleotides upstream of the translational start site. A GC-box precedes the transcriptional start site by 40 nucleotides. No consensus TATA or CAAT box sequences were identified in this region. Southern blot analysis of a Chinese hamster x mouse somatic cell hybrid panel and of the progeny of an inter-subspecies backcross mapped the Clone 5-encoded gene to mouse chromosome 19, the localization previously determined for the mouse homolog of the human beta 1AR gene. Binding studies of transient COS-7 transfectants and stable L-cell transfectants confirmed that Clone 5 encodes a beta AR of the beta 1 subtype. A probe derived from Clone 5 selectively hybridized in Northern blot studies to mRNA isolated from adult mouse cerebrum, lung, and heart. These data should serve as the basis for further studies of the regulation and function of the beta 1AR.

Abstract
Type-B leukemogenic retrovirus (TBLV) is a replication-competent type-B thymotropic retrovirus which lacks a transforming gene and whose genome is > 98% homologous to that of type-B mouse mammary tumor virus (MMTV). In contrast to MMTV, which induces mammary adenocarcinomas, TBLV induces a high incidence of T-cell thymic lymphomas in mice after a very short latent period. To investigate the molecular mechanisms by which TBLV induces T-cell lymphomas, we screened TBLV-induced tumor DNA for the frequent disruption of a particular cellular locus by TBLV proviral copies. In approximately 20% of the 55 primary tumors screened, the presence of proviruses in a common integration site was detected. This locus spans at least 53 kb of genomic DNA and maps to the mouse X chromosome. The presence of a functional gene at this locus is suggested by the conservation of nucleotide sequences from this locus among diverse animal species and by the expression of these sequences as mRNA in normal mouse tissues and tumors. The majority (17/18) of TBLV-induced primary tumors examined have elevated levels of this expressed mRNA.

Abstract
Cchl1a3 encodes the dihydropyridine-sensitive calcium channel alpha 1 subunit isoform predominantly expressed in skeletal muscle. mdg (muscular dysgenesis) has previously been implicated as a mutant allele of this gene. Hybridization of a rat brain cDNA probe for Cchl1a3 to Southern blots of DNAs from a panel of Chinese hamster x mouse somatic cell hybrids suggested that this gene maps to mouse Chromosome 1. Analysis of the progeny of an inbred strain cross-positioned Cchl1a3 1.3 cM proximal to the Pep-3 locus on Chr 1.

Abstract
The Hox-1.11 gene encodes a protein 372 amino acid residues long that contains a conserved pentapeptide, a homeodomain, and an acidic region. The amino acid sequence of the homeodomain of Hox-1.11 is identical to that of Hox-2.8, and the N-terminal and C-terminal regions of Hox-1.11 are similar to those of human HOX2H, which is the equivalent of murine Hox-2.8. The Hox-1.11 gene was shown to reside on murine chromosome 6, which contains the Hox-1 cluster of homeobox genes. One species of Hox-1.11 poly(A)+ RNA approximately 1.7 kb long was detected in mouse embryos, which is most abundant in 12-day-old embryos and progressively decreases during further embryonic development. The most anterior expression of Hox-1.11 poly(A)+ RNA in 12- to 14-day-old mouse embryos was shown by in situ hybridization to be in the mid and posterior hindbrain. Hox-1.11 poly(A)+ RNA also is expressed in the VII and VIII cranial ganglia, spinal cord, spinal ganglia, larynx, lungs, vertebrae, sternum, and intestine.

Abstract
We mapped the owl monkey colony-stimulating factor 1 receptor (CSF1R) locus to the proximal region of chromosome 3q of karyotype VI(K-VI) and karyotype V(K-V) and the interleukin 5 (IL5) locus to the mid-region of chromosome 3q(K-VI) and 19q(K-IV) using a combination of Southern hybridization of somatic cells and in situ chromosomal hybridization methodologies. The findings support the proposed evolution of owl monkey chromosome 3(K-VI) from a fusion of two smaller structures, the homologs of chromosomes 6 and 19 (K-IV). The data also indicate genomic conservation of the HSA 5q23-q35 segment in the higher primates.

Abstract
Two cDNAs that encode a protein with 87% identity to human cyclin B1 and that differ only in the length of their 3'-untranslated regions have been isolated from a 70Z/3B murine pre-B leukemia cell library. Three sizes of RNA transcripts were detected in Northern hybridization analyses of a variety of normal tissues and transformed cell lines using the cDNA inserts as probes. The expression of these RNAs can be modulated in tissue culture cell lines by physiologically relevant stimuli, increasing when cells are stimulated to proliferate and decreasing when cells are induced to differentiate. Moreover, RNAs from tissues that contain few proliferating cells have no detectable hybridizing transcripts. The coordinate regulation of these RNAs with other genes that are activated during the cell division cycle and the profound similarity of the predicted amino acid sequence to those of published cyclin B homologues indicate that these genes encode a murine cyclin B1. In Southern hybridization analysis of BALB/cAnPt genomic DNA digested with EcoRI, 12 fragments hybridized with the cDNA probes. Through Southern blot analyses of DNA from backcross and cogenic mice, recombinant inbred strains, and somatic cell hybrids, the genetic loci that produce the cyclin B1-related sequences (designated loci Cycb1-rs1 to Cycb1-rs9) were mapped on mouse chromosomes 5, 1, 17, 4, 14, 13, 7, X, and 8, respectively. Cycb1-rs6 (on chromosome 13) is discussed as the most likely candidate for an expressed structural gene locus.

Abstract
Ornithine aminotransferase (OAT), a mitochondrial matrix enzyme, is deficient in patients with gyrate atrophy of the choroid and retina. In human, the OAT structural gene maps to Chromosome (Chr) 10q26 and several OAT-related sequences, some of which are known to be processed pseudogenes, which map to Xp11.3-11.21. Here, we report chromosomal localization in the mouse of the OAT gene and related sequences. Genomic DNA blot analysis of a well-characterized panel of Chinese hamster x mouse somatic cell hybrids using a human OAT probe revealed two murine loci, one on mouse Chr 7 and the other on Chr X. In addition, segregation of restriction fragment length polymorphisms (RFLPs) detected by the OAT probe in recombinant inbred (RI) strains detected a third locus on Chr 3 and positioned the X locus near Cf-8 and Rsvp. Progeny of an intersubspecific backcross were used to map the Chr 7 locus between Tyr and Int-2, near Cyp2e-1.

Abstract
A 13.5-kb genomic fragment of the mouse cystic fibrosis transmembrane conductance regulator (CFTR) gene was isolated from a C57BL/6J liver DNA library, using a human CFTR exon 10 probe. This region of the human gene includes the most common cystic fibrosis mutation (deletion of the Phe508 residue) in the first nucleotide binding domain of CFTR. Sequence analysis demonstrated 87% identity between the predicted mouse and the normal human CFTR exon 10 sequences, including conservation of the Phe508 residue. Northern analysis revealed that the mouse gene is expressed in intestine, lung, stomach, kidney, and salivary gland. In contrast to human CFTR, murine CFTR transcripts were not detectable by Northern analysis in the liver or pancreas. More sensitive PCR analysis, however, revealed that the mouse CFTR gene is weakly expressed in other tissues, including liver and pancreas. During development, mouse CFTR transcripts were observed as early as Embryonic Day 13. Southern analysis of mouse x Chinese hamster somatic cell hybrid DNAs mapped the mouse CFTR locus (Cftr) to Chromosome 6 (Chr 6). Subsequent typing of the progeny of an interspecies backcross revealed that Cftr is closely linked to the proto-oncogene c-met locus (Met) in the centromeric region of mouse Chr 6, consistent with the observation that there is a conserved chromosomal segment on human chromosome 7 and mouse Chr 6.

Abstract
The large family of signal transducing proteins known as G proteins are heterotrimers that dissociate into an independent alpha-subunit and beta gamma-subunit complex after ligand binding or other stimulation. For G alpha, at least 30 distinct sequences representing 10 different classes have been identified. On the other hand, cDNAs for only three G beta-subunit genes have been isolated so far. All three of the G beta genes have been chromosomally mapped in the human, but only two in the mouse. Using a human retinal cDNA for the third G protein beta-subunit, we have mapped the corresponding gene, termed Gnb-3, to mouse Chromosome 6 with somatic cell hybrids and have positioned it distal to but near the marker Raf-1 by analysis of the progeny of three genetic crosses.

Abstract
Several cDNA clones of a gene termed male-enhanced antigen-2 (Mea-2), have been isolated from a mouse testicular expression cDNA library using a monoclonal histocompatability Y (H-Ys) antibody which detects specific protein(s) present in the mouse testis but not the ovary. The Mea-2 gene is phylogenetically conserved among various mammalian species examined, and is expressed at high levels in adult mouse testis. The expression pattern of Mea-2 is very similar to that of another gene, the male-enhanced antigen-1 (Mea-1), previously isolated using a polyclonal H-Ys antibody. Northern blotting and RT-PCR analyses demonstrated that Mea-2 is also expressed in other adult and fetal mouse organs at low levels. The testis-enhanced expression of this gene is associated with germ cell development at mid- to late-meiotic stages of spermatogenesis. Analysis of an intersubspecies mouse backcross has assigned this gene to chromosome 5, between the loci Gus and Hnf-1.

Abstract
The BALB/c mouse DNA was analyzed by field-inversion gel electrophoresis to determine the orientation and distance between the beta-platelet-derived growth factor receptor-encoding gene (Pdgfr) and the colony-stimulating factor 1 receptor-encoding gene (Csfmr). It was found that the 5' portion of the Pdgfr gene was cleaved by the enzyme ClaI into two fragments. The 425-kb fragment hybridized with a 3' Pdgfr and a 5' Csfmr probe. This result shows that the Csfmr gene is 3' relative to the Pdgfr gene, and suggests that the Pdgfr and Csfmr genes are physically linked.

Abstract
A rat brain cDNA probe was used to localize a gene encoding the alpha 1 subunit of neuronal dihydropyridine-sensitive L-type calcium channels in the mouse and human genomes. Hybridization of the probe to Southern blots made with DNAs from a Chinese hamster x mouse somatic cell hybrid panel indicated that this gene maps to mouse chromosome 14 (Chr 14). Southern blot analysis of an intersubspecies cross demonstrated that the calcium channel alpha 1 subunit gene, termed Cchl1a2, can be positioned 7.5 cM proximal to Np-1. Similarly, segregation among human X rodent somatic cell hybrids indicated that CCHL1A2 maps to human chromosome 3. These assignments are consistent with a region of linkage homology between human chromosome 3p and a proximal region of mouse Chr 14.

Abstract
Melanocytes preferentially express an mRNA species, Pmel 17, whose protein product cross-reacts with anti-tyrosinase antibodies and whose expression correlates with the melanin content. We have now analyzed the deduced protein structure and mapped its chromosomal location in mouse and human. The amino acid sequence deduced from the nucleotide sequence of the Pmel 17 cDNA showed that the protein is composed of 645 amino acids with a molecular weight of 68,600. The Pmel 17 protein contains a putative leader sequence and a potential membrane anchor segment, which indicates that this may be a membrane-associated protein in melanocytes. The deduced protein contains five potential N-glycosylation sites and relatively high levels of serine and threonine. Three repeats of a 26-amino acid motif appear in the middle of the molecule. The human Pmel 17 gene, designated D12S53E, maps to chromosome 12, region 12pter-q21; and the mouse homologue, designated D12S53Eh, maps to the distal region of mouse chromosome 10, a region also known to carry the coat color locus si (silver).

Abstract
The neurotransmitter serotonin (5-hydroxytryptamine, 5-HT) exerts diverse physiological effects in the central and peripheral nervous systems and in smooth muscle by interacting with pharmacologically distinct membrane receptors. We report here the cDNA cloning of the mouse 5-HT1C receptor and its functional expression in Xenopus oocytes. This receptor possesses the unusual feature of containing eight hydrophobic domains capable of forming membrane-spanning alpha-helices, contrary to the usual '7-helix' paradigm for other membrane receptors that function through coupling to GTP-binding proteins. By hybridization analysis of Chinese hamster x mouse somatic cell hybrid lines, the gene for the receptor, designated Htr1c, has been assigned to the mouse X chromosome.

Abstract
The mouse homolog of the Gibbon ape leukemia virus (GALV) receptor (Glvr-1) was mapped to mouse Chromosome 2 (Chr 2) by Southern blot analysis of somatic cell hybrids and positioned on this chromosome using an interspecies genetic cross. Mouse Chr 2 also encodes a receptor (Rec-2) for the wild mouse virus M813. To investigate whether Glvr-1 and Rec-2 could be the same gene, we sought evidence for sequence homology between the env- genes of their respective viruses. Southern blot hybridization with GALV-derived env and pol-env probes failed to detect any homology between GALV and M813, but did show that all mouse species tested carry numerous copies of GALV-related sequences. We speculate that a functional receptor for GALV-related viruses was expressed during Mus evolution.

Abstract
The HSP86 gene family in BALB/c, AKR/J, C58/J, and NFS/N inbred mice comprises an intron-containing expressed gene and, depending on the strain, two to four other HSP86-related members that are apparently processed pseudogenes. The expressed gene locus, Hsp86-1, was identified by its sequence identity with the mouse HSP86 cDNA coding region together with the presence of an intron at the same position as in the homologous human gene. Hsp86-1 was mapped 11.6 cM from the immunoglobulin heavy chain gene IgH on Chromosome 12 using an intersubspecies backcross. Two of the other loci that were common to all inbred strains tested, designated Hsp86-ps1 and Hsp86-ps2, were mapped to positions on Chromosomes 11 and 3, respectively. An HSP86-related locus specific to NFS/N and C58/J mice, designated Hsp86-ps3, was mapped on Chromosome 9. Also, an HSP86-related locus that was unique to NFS/N mice, designated Hsp86-ps4, was mapped to Chromosome 4.

Abstract
Southern blot analysis of DNAs from somatic cell hybrids and the progeny of an intersubspecies backcross were used to identify and chromosomally map four loci in the mouse containing sequences cross-reactive to members of the jun family of transcriptional activators. The murine homolog of v-jun, Jun, was mapped to chromosome (Chr) 4, and a locus containing jun B-related sequences (Junb) was mapped to Chr 8. Probes for jun D identified two genetic loci; one, Jund-1, is near Junb on Chr 8, and a second, previously unidentified locus termed Jund-2, was mapped to Chr 2.

Abstract
The pineal gland contains a soluble phosphoprotein, phosducin, which is homologous to that of retinal photoreceptors. Phosducin has been shown to bind the beta, gamma subunits of the retinal G-protein transducin. Retinal phosducin has been cloned and now we report a rat pineal cDNA encoding phosducin. A 1217-nucleotide cDNA was isolated from a rat pineal library by DNA-DNA hybridization with a polymerase chain reaction-amplified cDNA of bovine retina mRNA for phosducin. Northern blot analysis demonstrates that the mRNA for phosducin is approximately 1.3 kb in both rat pineal and rat retina. The translated mRNA from rat pineal encodes a protein with 246 amino acids, compared to the 245 amino acids of bovine retina phosducin. The predicted molecular weight of rat pineal phosducin is 28,201. Immunoblot analysis with affinity-purified antibodies against bovine retina phosducin identify a single immunoreactive protein of approximately 33 kDa in both rat retina and rat pineal. The amino acid sequence of rat pineal phosducin is homologous to that of bovine retina phosducin, revealing 89% identity and another 5.7% similarity. Both rat pineal and bovine retina phosducins are acidic proteins with pIs of 4.3 and 4.5, respectively. The translated protein lacks hydrophobic domains that would suggest an integral membrane protein. Rat pineal phosducin has a single consensus phosphorylation domain for protein kinase A that is nearly identical to that of retinal phosducin, which is phosphorylated by protein kinase A in situ. Rat phosducin also contains three potential phosphorylation domains for protein kinase C and nine for casein kinase II as well as a predicted site for N-glycosylation. The cDNA encoding phosducin was used to localize the gene within a linkage group to a large segment of mouse chromosome 1 in a conserved region with the long arm of human chromosome 1 with a panel of DNA samples from an interspecific cross. In keeping with a proposed role of retinal phosducin in down-regulation of the photo-transduction cascade, a modulatory role in signal transduction is proposed for pineal phosducin.

Abstract
Glutamate dehydrogenase (GLUD) plays an important role in mammalian neuronal transmission. In human, GLUD is encoded by a small gene family. To determine whether defects in Glud genes are associated with known neurological mutations in the mouse and to contribute to the comparative mapping of homologous genes in man and mouse, the chromosomal location of genes reactive with a mouse brain GLUD cDNA were determined. Genomic Southern analysis of a well-characterized panel of Chinese hamster x mouse somatic cell hybrids identified two GLUD-reactive loci, one residing on mouse Chromosome 14 and the other on Chromosome 7. Progeny of an intersubspecies backcross were used to map one of these genes, Glud, proximal to Np-1 on Chromosome 14, but no restriction fragment polymorphisms could be identified for the second locus, Glud-2.

Abstract
Intercellular adhesion molecule-1 (ICAM-1) is an integral membrane protein, a member of the immunoglobulin superfamily, and a ligand for LFA-1, a beta 2 leukocyte integrin. ICAM-1 has a tissue distribution similar to that of the major histocompatibility complex class II antigens and is likely to play a role in inflammatory responses. We have mapped this gene to proximal mouse chromosome 9 by using mouse-hamster somatic cell hybrids and an interspecies backcross. Since human ICAM-1 maps to chromosome 19, it joins the LDL receptor to establish a new conserved syntenic segment between human chromosome 19 and proximal mouse chromosome 9. Murine Icam-1 maps between Cbl-2 and the centromere in the same region as one of the susceptibility genes for insulin-dependent diabetes mellitus (Idd-2) that is postulated to play a role in immune function and inflammation leading to insulitis. The mapping of Icam-1 to the region known to contain the Idd-2 gene raises the question of whether the phenotypic differences attributed to the Idd-2 locus might be due to genetic variation in Icam-1.

Abstract
The murine GABAA/benzodiazepine (GABAA/BZ) receptor alpha 1 subunit cDNA has been isolated from a BALB/c mouse brain library and sequenced. The cDNA is 2665 nucleotides long with an open reading frame of 455 amino acids. It shows significant homology to the GABAA receptor alpha 1 subunit cDNA sequences of other species. Excluding deletions, the murine GABAA alpha 1 receptor exhibits 96% nucleotide and 100% amino acid sequence homology to the rat alpha 1 receptor cDNA and over 91% nucleotide and 98% amino acid sequence homology to the bovine and human alpha 1 receptor cDNAs in the protein coding region. This murine cDNA was used to locate the alpha 1 receptor subunit gene, Gabra-1, to murine Chromosome 11 between Il-3 and Rel. This assignment extends proximally the segment of mouse Chromosome 11 with known homology to human chromosome 5.

Abstract
The alpha 3, alpha 5, and beta 4 genes (human gene symbols CHRNA3, CHRNA5, and CHRNB4 respectively; mouse gene symbols Acra-3, Acra-5, and Acrb-4, respectively) are members of the nicotinic acetylcholine receptor gene family and are clustered within a 68-kb segment of the rat genome (Boulter et al., 1990, J. Biol. Chem. 265:4472). By somatic cell hybrid analysis, three cDNAs corresponding to these genes were used to map the homologous loci to human chromosome 15 and to mouse chromosome 9. Linkage analysis using CEPH pedigrees showed that the CHRNA5 gene was closely linked to the following chromosome 15 loci: D15S46, D15S52, D15S28, D15S34, and D15S35. Using interspecies crosses in mice, the Acra-5 gene was found closely linked to the Mpi-1 locus. The mapping of these members of a neurotransmitter receptor gene family may facilitate the identification of relationships between the neurotransmitter receptors and murine or human phenotypes.

Abstract
We have isolated and sequenced part of a new gene of the tyrosine kinase family. This gene, called FLT3, has strong sequence similarities with members of a group of genes encoding growth factor receptors: FMS, KIT, and PDGFR. We have localized the human FLT3 gene to chromosome 13, band q12, and its mouse homolog to chromosome 5, region G.
