Cloning of a human collagen-binding protein, and its homology with rat gp46, chick hsp47 and mouse J6 proteins

Biochim Biophys Acta. 1992 Jan 6;1129(2):246-8. doi: 10.1016/0167-4781(92)90498-o.


Several cDNA clones encoding a collagen-binding protein were isolated from human fibroblasts. The cDNA encoded a 417 amino acid protein, containing two potential N-linked oligosaccharide binding sites and a C-terminal RDEL sequence, which has been shown to act as an endoplasmic retention signal in other systems. The derived amino acid sequence of the protein shows close homology with gp46 from rat skeletal myoblasts, J6 protein from mouse F9 embryonal carcinoma cells and hsp47 from chick embryo fibroblasts. It also shows sequence similarity with members of the serpin family.
