The protein encoded by this gene is a member of the glucuronyltransferase gene family. These enzymes exhibit strict acceptor specificity, recognizing nonreducing terminal sugars and their anomeric linkages. This gene product functions as the key enzyme in a glucuronyl transfer reaction during the biosynthesis of the carbohydrate epitope HNK-1 (human natural killer-1, also known as CD57 and LEU7). Alternate transcriptional splice variants have been characterized. [provided by RefSeq, Jul 2008]
B3GAT1 (Beta-1,3-Glucuronyltransferase 1) is a Protein Coding gene. Diseases associated with B3GAT1 include Renal Adenoma and Chronic Nk-Cell Lymphocytosis. Among its related pathways are heparan sulfate biosynthesis and Chondroitin sulfate/dermatan sulfate metabolism. Gene Ontology (GO) annotations related to this gene include UDP-galactose:beta-N-acetylglucosamine beta-1,3-galactosyltransferase activity and galactosylgalactosylxylosylprotein 3-beta-glucuronosyltransferase activity. An important paralog of this gene is B3GAT2.
