Predicted to enable galactosylgalactosylxylosylprotein 3-beta-glucuronosyltransferase activity. Predicted to be involved in carbohydrate metabolic process and chondroitin sulfate proteoglycan biosynthetic process. Predicted to be located in Golgi membrane. Human ortholog(s) of this gene implicated in Barrett's esophagus and schizophrenia. Is an ortholog of human B3GAT1 (
beta-1,3-glucuronyltransferase 1) and B3GAT2 (
beta-1,3-glucuronyltransferase 2).
