Q99715

FUNCTION: Type XII collagen interacts with type I collagen- containing fibrils, the COL1 domain could be associated with the surface of the fibrils, and the COL2 and NC3 domains may be localized in the perifibrillar matrix (By similarity). SUBUNIT: Trimer of identical chains each containing 190 kDa of non-triple-helical sequences. SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular matrix (By similarity). ALTERNATIVE PRODUCTS: Event=Alternative splicing; Named isoforms=3; Comment=The final tissue form of collagen XII may contain homotrimers of either isoform 1 or isoform 2 or any combination of isoform 1 and isoform 2; Name=1; Synonyms=Long; IsoId=Q99715-1; Sequence=Displayed; Name=2; Synonyms=Short; IsoId=Q99715-2; Sequence=VSP_001149; Name=4; IsoId=Q99715-4; Sequence=VSP_024942; TISSUE SPECIFICITY: Found in collagen I-containing tissues: both isoform 1 and isoform 2 appear in amnion, chorion, skeletal muscle, small intestine, and in cell culture of dermal fibroblasts, keratinocytes and endothelial cells. Only isoform 2 is found in lung, placenta, kidney and a squamous cell carcinoma cell line. Isoform 1 is also present in the corneal epithelial Bowman's membrane (BM) and the interfibrillar matrix of the corneal stroma, but it is not detected in the limbal BM. PTM: The triple-helical tail is stabilized by disulfide bonds at each end (By similarity). PTM: Hydroxylation on proline residues within the sequence motif, GXPG, is most likely to be 4-hydroxy as this fits the requirement for 4-hydroxylation in vertebrates (By similarity). PTM: Isoform 1 O-glycosylation; glycosaminoglycan of chondroitin- sulfate type (By similarity). SIMILARITY: Belongs to the fibril-associated collagens with interrupted helices (FACIT) family. SIMILARITY: Contains 4 collagen-like domains. SIMILARITY: Contains 18 fibronectin type-III domains. SIMILARITY: Contains 1 laminin G-like domain. SIMILARITY: Contains 4 VWFA domains.
