Genomic organization of the human procollagen α1(II) collagen gene

Abstract

The nucleotide sequence of the human procollagen α1(II) collagen gene extending from within the first intron through exon 15, and part of the 15th intron has been determined. This sequence analysis (7056 bases) identifies the intron/exon organization of the region of this gene encoding the N-propeptide and part of the triple-helical domain. Structural comparison of this with the genes of other human fibrillar collagens shows considerable diversity in terms of size and number of introns and exons that encodes the N-propeptide domain. Although the genomic structure of the human procollagen α1(II) gene is quite different from the rat procollagen α1(II) gene, the nucleotide coding sequences are 89% identical.
