Predicted to enable UDP-galactose:beta-N-acetylglucosamine beta-1,3-galactosyltransferase activity. Predicted to be involved in protein glycosylation. Predicted to act upstream of or within oligosaccharide biosynthetic process. Predicted to be integral component of membrane. Predicted to be active in Golgi membrane. Orthologous to human B3GALNT1 (beta-1,3-N-acetylgalactosaminyltransferase 1 (globoside blood group)). [provided by Alliance of Genome Resources, Apr 2022]
