Predicted to enable glucuronosyltransferase activity. Acts upstream of or within axon guidance and protein glycosylation. Predicted to be located in Golgi apparatus. Is expressed in several structures, including alimentary system; nervous system; reproductive system; respiratory system; and thymus. Used to study muscular dystrophy-dystroglycanopathy. Human ortholog(s) of this gene implicated in congenital muscular dystrophy-dystroglycanopathy type A13. Orthologous to human B4GAT1 (beta-1,4-glucuronyltransferase 1).
