Predicted to enable collagen binding activity and platelet-derived growth factor binding activity. Predicted to be an extracellular matrix structural constituent. Predicted to be involved in endodermal cell differentiation; extracellular matrix organization; and gonad development. Predicted to act upstream of or within cellular response to amino acid stimulus. Predicted to be located in extracellular region and sarcolemma. Predicted to be part of collagen type IX trimer. Predicted to be active in basement membrane and extracellular space. Human ortholog(s) of this gene implicated in Ullrich congenital muscular dystrophy. Orthologous to human COL6A1 (collagen type VI alpha 1 chain). [provided by Alliance of Genome Resources, Apr 2022]
