Predicted to enable acetylgalactosaminyltransferase activity. Acts upstream of or within UDP-N-acetylglucosamine metabolic process and protein glycosylation. Predicted to be located in Golgi apparatus and membrane. Predicted to be integral component of Golgi membrane. Is expressed in bladder fundus; hindgut; and midgut. Orthologous to human B4GALNT2 (beta-1,4-N-acetyl-galactosaminyltransferase 2). [provided by Alliance of Genome Resources, Apr 2022]
