Identification of genomic DNA coding for chicken type II procollagen.
A segment of the type II procollagen gene has been isolated by screening a lambda Charon 4A library containing fragments of chicken genomic DNA. The specific clone, LgCOL(II), was selected by hybridization using overlapping inserts from two cDNA clones which are specific for a cartilage procollagen (Vuorio, E., Sandell, L., Kravis, D., Sheffield, V. C., Vuorio, T., Dorfman, A., and Upholt, W. B. (1982) Nucleic Acids Res. 10, 1175-1192). DNA sequence analysis of LgCOL(II) in the COOH-telopeptide region of the protein, shows conclusively that this DNA corresponds to the chicken type II procollagen gene. Hybridization of cDNA probes to restriction fragment gel blots together with DNA sequence analysis have established the orientation and position of the procollagen gene within the lambda Charon 4A vector and indicate that LgCOL(II) contains approximately 6 kilobase pairs of the type II procollagen gene plus additional DNA flanking the 3' end of the gene. DNA sequence analysis shows directly that LgCOL(II) contains DNA sequences identical with those in the cDNA clones. The portion of the gene from amino acid 578 of the triple helical region to the COOH-terminal end of the protein (approximately 700 amino acids) is contained within the clone, corresponding to approximately 50% of the amino acid coding sequence of the gene. This region of the chicken alpha 1 (type II) procollagen gene is encoded within a shorter segment of the chicken genome than is the corresponding region of the alpha 2(type I) procollagen gene.
