Predicted to enable glucuronosyltransferase activity. Predicted to be involved in protein O-linked mannosylation. Predicted to act upstream of or within axon guidance and protein glycosylation. Predicted to be located in Golgi apparatus. Human ortholog(s) of this gene implicated in congenital muscular dystrophy-dystroglycanopathy type A13. Orthologous to human B4GAT1 (beta-1,4-glucuronyltransferase 1). [provided by Alliance of Genome Resources, Apr 2022]
