This gene encodes a member of the beta-1,3-N-acetylglucosaminyltransferase family. This enzyme is a type II transmembrane protein and contains a signal anchor that is not cleaved. It prefers the substrates of lacto-N-tetraose and lacto-N-neotetraose, and is involved in the biosynthesis of poly-N-acetyllactosamine chains and the biosynthesis of the backbone structure of dimeric sialyl Lewis a. It plays dominant roles in L-selectin ligand biosynthesis, lymphocyte homing and lymphocyte trafficking. [provided by RefSeq, Jul 2008]
B3GNT3 (UDP-GlcNAc:BetaGal Beta-1,3-N-Acetylglucosaminyltransferase 3) is a Protein Coding gene. Among its related pathways are Keratan sulfate/keratin metabolism and Glycosaminoglycan metabolism. Gene Ontology (GO) annotations related to this gene include galactosyltransferase activity and beta-1,3-galactosyl-O-glycosyl-glycoprotein beta-1,3-N-acetylglucosaminyltransferase activity. An important paralog of this gene is B3GNT6.
