Abstract
The folding of a collagen triple helix usually requires the presence of additional sequences that contribute to the association and correct alignment of the collagen chains. We recently reported that the C-terminal neck and lectin domains of a collagenous C-type lectin, rat pulmonary surfactant protein D (SP-D), are sufficient to drive the trimerization of a heterologous type IIA procollagen amino propeptide sequence. However, the conformation of the resulting trimeric IIA propeptide and the specific contributions of the SP-D sequence to trimerization were not elucidated. In the present study, we show that trimerization of the fusion protein is associated with correct folding of the collagen helix within the IIA propeptide domain (as assessed by circular dichroism) and that the constituent chains are hydroxylated. Chemical cross-linking and analytical ultracentrifugation showed that the IIA amino-propeptide retains its trimeric configuration even after proteolytic removal of the SP-D domains. By contrast, IIA amino-propeptides synthesized without fusion to the neck or lectin domains are assembled exclusively as monomers. To localize the trimerization sequence, mutant chimeric cDNA constructs were designed containing premature termination codons within the coiled-coil neck domain. A short, 14-amino acid sequence corresponding to the first two heptad repeats of the neck domain was sufficient to drive the trimeric association of the IIA amino-propeptide alpha-chains. However, deletion of the collagen domain resulted in the secretion of monomers. These studies demonstrate that two heptad repeats are sufficient for trimeric association of the propeptide but indicate that cooperative interactions between the coiled-coil and collagen domains are required for the formation of a stable helix.

Abstract
The impetus for this review comes from the recent finding that the absence of the majority of the non-triple-helical sequence in the NH(2)-terminal propeptide (N-propeptide) of the pro alpha 1(I) collagen chain fails to generate a significant phenotype in the mouse (Bornstein et al., J. Biol. Chem., 277:2605-2613, 2002). This result is in apparent conflict with those of numerous studies in vitro that have implicated the N-propeptide in a number of processes that are involved in the biogenesis, maturation and function of type 1 collagen. To seek an explanation for this discrepancy, the sequences of the highly conserved, 55-57-amino acid, cysteine-rich repeats (CRR), which constitute the majority of the globular domains in the N-propeptides, were compared among 13 vertebrate species. Surprisingly, the CRR in mice and rats differs substantially from those in other mammalian species. Indeed, the CRR in birds, fish and amphibia are more similar to those of other mammals than are the CRR in rodents. This finding raises the possibility that the mutant mouse, which lacks exon 2 that encodes the CRR in the N-propeptide, might not be an appropriate model in which to study the function of the N-propeptide in other mammals. Alternatively, compensation, possibly by procollagens II or III, could account for the mild phenotype of the exon 2-deleted mouse. Yet another possibility is that the CRR plays a developmental role in the mouse, akin to that recently proposed for the N-propeptide in type IIA procollagen, rather than a function in collagen biogenesis. Some support for the latter possibility is provided by the observation that, on one background, the breeding of heterozygous exon 2-deleted mice generated homozygous mutants at less than the expected frequency. Experiments to examine these possibilities are proposed.

Abstract
The disease phenotype of oculo-skeletal dysplasia (OSD) detected in Labrador retrievers and Samoyeds shows a large degree of similarity with human Stickler and Kniest dysplasia. Type II collagen (COL2A1) mRNA, which is defective in a larger number of Stickler and Kniest patients, has been cloned and characterized from normal dog. The amino acid sequence of the canine type II procollagen is predicted to contain 1487 residues, with high degree of homology with its human homologue, and maintains all the characteristic structural domains. In addition to cartilage, expression of COL2A1 has also been detected in canine retina and testes. In testes, the N-propeptide region of COL2A1 displayed differential splicing and expressed both splice variants, IIA (with exon 2) and IIB (without exon 2), suggesting the importance of both forms in testis maturation and maintenance. Despite a severe decrease of type II collagen protein in the vitreous of OSD affected Labrador retrievers, COL2A1 gene has been excluded from having any causal association with the disease locus by linkage analysis. Using an intragenic RFLP marker, COL2A1 gene has also been tested as a candidate gene for the non-allelic form of the other canine OSD identified in Samoyeds, and excluded by linkage analysis. Oculo-skeletal dysplastic Labrador retriever and Samoyed provide two animal models for chondrodysplasia with genetic heterogeneity.

Abstract
Heterogeneity has long been recognised within the spectrum of inherited vitreo-retinal disease but the extent of the variation has been less easy to quantify. This has been compounded by the small size and numbers of pedigrees available for the study, and the phenotypic variation both within and between pedigrees. Formation abnormalities in the vitreous architecture have, in the past, been eclipsed by classifications based on general skeletal and morphological differences. Stickler syndrome is the commonest disorder within the spectrum of hereditary vitreous abnormalities and many of the recent published advances relate to this. Stickler syndrome has been subclassified on the basis of vitreo-retinal phenotype: type 1 families with a characteristic congenital vitreous anomaly show linkage without recombination to markers at the COL2A1 locus; type 2 families with different congenital vitreo-retinal phenotypes are not linked to COL2A1. A recent report identifies the COL11A2 mutation in a Dutch pedigree with systemic features of Stickler syndrome but without ocular involvement. Others have implicated COL11A1 in a type 2 Stickler syndrome pedigree with ocular abnormalities. Both COL11A1 and COL11A2 are expressed in cartilage, but on the basis of studies of bovine vitreous it is likely that only the alpha 1(XI) chain encoded by COL11A1 is present in vitreous. This would be consistent with the hypothesis that mutations in the genes encoding collagen XI can give rise to manifestations of Stickler syndrome, but of these, only mutations in COL11A1 will give the full syndrome including the vitreo-retinal features.

Abstract
Northern analyses, RNAase protection assays and in situ hybridizations were used to study the expression of the mRNA for the alpha 2 chain of collagen XI and the two different mRNAs generated from the collagen II gene through alternative splicing of exon 2 in several different tissues of 15-19-week-old fetuses. The highest expression levels of procollagen alpha 2(XI) and alpha 1(II) mRNAs were detected in cartilage, but, using long exposure times, Northern hybridization revealed the presence of the approximately 5.3 kb procollagen alpha 1(II) mRNA in most tissues analysed: calvarial and diaphyseal bone, striated and cardiac muscle, skin, brain, lung, kidney, liver, small intestine and colon. Both alternatively spliced forms of the mRNA were present in these tissues. In cartilage, the short form of the procollagen alpha 1(II) mRNA (without exon 2 sequences) was clearly more abundant, whereas in most of the non-cartilaginous tissues the long form was the predominant one. Low levels of procollagen alpha 2(XI) mRNA were also seen in non-cartilaginous tissues: calvarial and diaphyseal bone, kidney, skin, muscle, intestine, liver, brain, and lung. In all the other positive tissues except brain cortex, both collagen II and XI transcripts were observed. The localization of collagen II and XI signals was identical in cartilage, kidney and skin. However, in cartilage the signal with collagen II probe was much higher than that with the collagen alpha 2(XI) probe. In epidermis the situation was reversed. Our results show considerable co-expression and co-localization of procollagen alpha 1(II) and alpha 2(XI) mRNAs in many tissues of developing human fetuses. Since the collagen alpha 1(II) gene also codes for the alpha 3(XI) chain of collagen XI we propose that some, but not all, of the expression of the collagen II gene in non-cartilaginous tissues relates to collagen XI production.

Abstract
We have completed the analysis of a genomic clone, G238, that contains most of the coding region of the sponge COLF1 fibrillar collagen gene. The main triple helical domain is encoded by 31 exons. Except for the 5' junction exon and the two last 3' exons (126 and 18 base pairs), all these exons are related to a 54-bp unit and begin with an intact glycine codon. A good correlation can be made between this sponge gene and a vertebrate fibrillar collagen gene, revealing the high conservation of the members of this family during evolution. The reconstitution of an ancestral collagen gene can be made by considering all the exon/intron junctions of these genes. We suggest that such an ancestral gene arose from multiple duplications of a 54-bp exon and a (54 + 45)-bp module.

Abstract
Type V collagen is a minor represented and poorly characterized fibrillar collagen type. Previous cDNA cloning experiments showed that the amino-propeptide of the pro-alpha 2(V) chain shares structural features in common with pro-alpha 1(I), pro alpha 1(II) and pro-alpha 1(III) collagens. In the present paper, this analysis was extended to the gene level. Accordingly the exon/intron arrangement of the amino-propeptide coding domain was compared among pro-alpha 1(I) (COL1A1), pro alpha 1(II) (COL2A1), pro-alpha 1(III) (CO13A1) and pro-alpha 2(V) (COL5A2) collagen genes. This revealed that COL3A1 is the most closely related gene to COL5A2. Based on the assumption that critical regulatory elements might be phylogenetically conserved, we also compared the promoter sequences of the mouse and human COL5A2 genes. This revealed the highest level of sequence homology (97%) in a 52-bp segment which was previously shown to be essential in conferring cell type specificity to the human promoter.

Abstract
We have developed a method to isolate RNA in high yield from adult articular cartilage. Homogenization of the articular cartilage with a freezer mill, extraction with 4 M guanidinium isothiocyanate/acid-phenol, and ultracentrifugation in cesium trifluoroacetate was found to be an effective and practical method for isolating a high yield of intact RNA from adult canine articular cartilage. The total RNA was suitable for Northern blot analysis. The mRNA that could then be isolated by oligo-dT affinity chromatography was found to be a suitable substrate for in vitro translation, for making a cDNA library, and for PCR amplification.

Abstract
The direct sequencing of the human type II procollagen (COL2A1) gene from polymerase chain reaction (PCR)-amplified genomic DNA is described. Thirty-two regions of the COL2A1 gene were asymmetrically amplified with intron primers which were specifically chosen to amplify a region spanning 500 to 800 bp of sequence encoding one or more exons and their accompanying intervening sequences. Primers for dideoxynucleotide sequencing of the PCR products were then designed to provide complete exon sequence information and to insure that intron:exon splice junction sequence data would be obtained. Amplification and sequencing reactions were performed on an automated workstation to facilitate the handling of multiple DNA templates. The procedure allowed efficient sequencing of over 25,000 bp of each allele of the COL2A1 gene per diploid genome. We used this method for the comparative analyses of COL2A1 sequences in DNA isolated from the blood of 42 unrelated individuals and we identified 21 neutral sequence variants in the gene. The sequence variations were confirmed by independent assays, including restriction enzyme digestion. The sequence variants described here will be important for identifying haplotypes of the type II procollagen gene that will be useful in defining a genetic etiology for diseases of cartilaginous tissues.

Abstract
Type II collagen is a major component of cartilage providing structural integrity to the tissue. Type II procollagen can be expressed in two forms by differential splicing of the primary gene transcript. The two mRNAs either include (type IIA) or exclude (type IIB) an exon (exon 2) encoding the major portion of the amino (NH2)-propeptide (Ryan, M. C., and L. J. Sandell. 1990. J. Biol. Chem. 265:10334-10339). The expression of the two procollagens was examined in order to establish a potential functional significance for the two type II procollagen mRNAs. First, to establish whether the two mRNAs are functional, we showed that both mRNAs can be translated and the proteins secreted into the extracellular environment. Both proteins were identified as type II procollagens. Secondly, to test the hypothesis that differential expression of type II procollagens may be a marker for a distinct population of cells, specific procollagen mRNAs were localized in tissue by in situ hybridization to oligonucleotides spanning the exon junctions. Embryonic vertebral column was chosen as a source of tissue undergoing rapid chondrogenesis, allowing the examination of a variety of cell types related to cartilage. In this issue, each procollagen mRNA had a distinct tissue distribution during chondrogenesis with type IIB expressed in chondrocytes and type IIA expressed in cells surrounding cartilage in prechondrocytes. The morphology of the cells expressing the two collagen types was distinct: the cells expressing type IIA are narrow, elongated, and "fibroblastic" in appearance while the cells expressing type IIB are large and round. The expression of type IIB appears to be correlated with abundant synthesis and accumulation of cartilagenous extracellular matrix. The expression of type IIB is spatially correlated with the high level expression of the cartilage proteoglycan, aggrecan, establishing type IIB procollagen and aggrecan as markers for the chondrocyte phenotype. Transcripts of type II collagen, primarily type IIA, are also expressed in embryonic spinal ganglion. While small amounts of type II collagen have been previously detected in noncartilagenous tissues, the detection of this new form of the collagen in relatively high abundance in embryonic nerve tissue is unique. Taken together, these findings imply a potential functional difference between type IIA and type IIB procollagens and indicate that the removal of exon 2 from the pre-mRNA, and consequently the NH2-propeptide from the collagen molecule, may be an important step in chondrogenesis. In addition, type II procollagen, specifically type IIA, may function in noncartilage tissues, particularly during development.

Abstract
A new procedure for preparing cosmid libraries was used to isolate three alleles for the human gene for type II procollagen (COL2A1). Over 20,000 bp of one allele were completely sequenced and over 10,000 bp of the two other alleles were sequenced. The data located and defined 26 exons and introns of the gene not previously analyzed. The results completed the structure of the gene except for the newly discovered exon 2A that undergoes alternative splicing (Ryan et al., 1990, Trans. Ann. Meet. Orthop. Res. Soc. 15:65). As a result, it is the most completely known structure of a gene for a human fibrillar collagen. The results confirm the previous impression that exon sizes are highly conserved among the genes for the three major fibrillar collagens. Comparison of clones from the three alleles defined five neutral variations in coding sequences and seven variations in the intron that also are probably neutral variations. The normal sequences and the variations in sequences will be important for identifying different alleles and haplotypes of the gene and for the analysis of genetic mutations in the gene that cause diseases of cartilage such as chondrodysplasias and osteoarthritis.

Abstract
The complete DNA sequence (6 kb) of the 5' portion of the human type II procollagen gene (COL2A1) was determined from the promoter through the third exon including intron sequences and 690 bp of 5' flanking sequence. Three regions between -501 and -649 in the human promoter share high sequence homology to the rat type II procollagen gene and suggest that the functional sequences within the promoter may extend to at least 649 bp upstream from the start site of transcription. The first intron of the human gene contains elements known to play a role in transcription of other genes: three GC boxes, an inverted repeat with homology to a serum responsive element, a viral core enhancer motif, a high-affinity recognition sequence for nuclear factor-1, and an alternating purine/pyrimidine stretch composed of GT repeats. Both the promoter and a portion of the first intron have a high percentage of G + C residues and a high frequency of CpG dinucleotides. In addition, a protein domain that has been identified in the human COL2A1 gene is present in pro-alpha 1(I) and pro-alpha 1(III) collagen but was not previously described for pro-alpha 1(II) collagen. On the basis of this new information we present a modified gene structure for the exons encoding the pro-alpha 1(II) collagen NH2-propeptide.

Abstract
A cosmid clone was isolated that contained an allele for the type II procollagen gene previously shown to be coinherited with primary generalized osteoarthritis in a large family. Affected members of the family had evidence of a mild chondrodysplasia, but they developed progressive osteoarthritic changes in many joints that had no epiphyseal deformities. The clone contained 52 of the 54 exons of the gene. Nucleotide sequencing of greater than 20,000 base pairs from the clone demonstrated that all the coding sequences and all the intron-exon boundaries were normal except for a single base mutation that converted the codon for arginine at position 519 of the alpha 1(II) chain to a codon for cysteine, an amino acid not found in type II collagen from humans or a variety of other species. The mutation was found in all affected members of the family but not in unaffected members or in 57 unrelated individuals.

Abstract
We have isolated overlapping clones containing the 5'-terminal portion of the human pro-alpha 1(III) collagen gene (COL3A1). This has enabled us to extend our previous studies and thus generate a restriction map of nearly 64 kb of DNA encompassing all of COL3A1 and more than 20 kb of flanking sequences. Aside from the complete nucleotide and amino acid sequences of type-III N-pre-propeptide, this study has established the number of the corresponding exons, whose relative organization deviates from the pattern observed in the analogous regions of type-I procollagen genes, COL1A1 and COL1A2. Moreover, we have sequenced 1628 bp of the 5'-flanking region of COL3A1, from the transcription start point (tsp) to an AluI repetitive element. Pairwise comparison with the analogous segment of the mouse gene has showed 78% sequence similarity in nearly 270 bp immediately preceding the tsp and including the TATA element and a presumptive NF-1 binding site. Relatively close to the tsp, but upstream from the region of homology with the murine gene, a potential AP-1 binding site has also been identified.

Abstract
Spondyloepiphyseal dysplasias (SED) are a heterogeneous group of inherited disorders characterized by disproportionate short stature and pleiotropic involvement of the skeletal and ocular systems. Evidence has suggested that SED may result from structural defects in type II collagen. To confirm the validity of this hypothesis, the structure of the "candidate" type II collagen gene (COL2A1) has been directly examined in a relatively large SED family. Coarse scanning of the gene by Southern blot hybridization identified an abnormal restriction pattern in one of the affected members of the kindred. Analysis of selected genomic fragments, amplified by the polymerase chain reaction, precisely localized the molecular defect and demonstrated that all affected family members carried the same heterozygous single-exon deletion. As a consequence of the mutation, nearly 90 percent of the assembled type II collagen homotrimers are expected to contain one or more procollagen subunits harboring an interstitial deletion of 36 amino acids in the triple helical domain.
