Collagen alpha-1(XIX) chain is a protein that in humans is encoded by the COL19A1 gene.This gene encodes the alpha chain of type XIX collagen a member of the FACIT collagen family (fibril-associated collagens with interrupted helices). Although the function of this collagen is not known other members of this collagen family are found in association with fibril-forming collagens such as type I and II and serve to maintain the integrity of the extracellular matrix.
