Collagen alpha-1(XII) chain is a protein that in humans is encoded by the COL12A1 gene.This gene encodes the alpha chain of type XII collagen a member of the FACIT (fibril-associated collagens with interrupted triple helices) collagen family. Type XII collagen is a homotrimer found in association with type I collagen an association that is thought to modify the interactions between collagen I fibrils and the surrounding matrix.
