Predicted to be an extracellular matrix structural constituent conferring tensile strength. Predicted to be involved in endodermal cell differentiation. Predicted to act upstream of or within cell adhesion. Located in collagen-containing extracellular matrix and extracellular space. Is expressed in several structures, including connective tissue; mitral valve; sensory organ; skeleton; and skin. Human ortholog(s) of this gene implicated in Ullrich congenital muscular dystrophy. Orthologous to human COL12A1 (collagen type XII alpha 1 chain). [provided by Alliance of Genome Resources, Apr 2022]
