Predicted to enable beta-N-acetylglucosaminylglycopeptide beta-1,4-galactosyltransferase activity; manganese ion binding activity; and xylosylprotein 4-beta-galactosyltransferase activity. Predicted to be involved in several processes, including glycoprotein biosynthetic process; glycosaminoglycan biosynthetic process; and negative regulation of fibroblast proliferation. Predicted to be integral component of membrane. Predicted to be active in Golgi apparatus. Human ortholog(s) of this gene implicated in Ehlers-Danlos syndrome and Ehlers-Danlos syndrome spondylodysplastic type 1. Orthologous to human B4GALT7 (beta-1,4-galactosyltransferase 7).
