Predicted to enable acetylgalactosaminyltransferase activity. Predicted to be involved in protein O-linked glycosylation. Predicted to be located in endoplasmic reticulum. Predicted to be active in Golgi membrane. Human ortholog(s) of this gene implicated in congenital muscular dystrophy-dystroglycanopathy type A11. Orthologous to human B3GALNT2 (beta-1,3-N-acetylgalactosaminyltransferase 2). [provided by Alliance of Genome Resources, Apr 2022]
