Predicted to enable UDP-glycosyltransferase activity. Predicted to be involved in glycosylation. Predicted to be active in endoplasmic reticulum membrane. Is expressed in adult head. Orthologous to several human genes including UGT1A3 (UDP glucuronosyltransferase family 1 member A3); UGT1A4 (UDP glucuronosyltransferase family 1 member A4); and UGT1A8 (UDP glucuronosyltransferase family 1 member A8).
