Summaries for B3GNT3 Gene

Entrez Gene Summary for B3GNT3 Gene

  • 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]

GeneCards Summary for B3GNT3 Gene

B3GNT3 (UDP-GlcNAc:BetaGal Beta-1,3-N-Acetylglucosaminyltransferase 3) is a Protein Coding gene. Among its related pathways are Mucin type O-glycan biosynthesis and O-linked glycosylation. 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.

UniProtKB/Swiss-Prot for B3GNT3 Gene

  • Beta-1,3-N-acetylglucosaminyltransferase involved in the synthesis of poly-N-acetyllactosamine. Has activity for type 2 oligosaccharides (PubMed:11042166). Also acts as a core1-1,3-N-acetylglucosaminyltransferase (Core1-beta3GlcNAcT) to form the 6-sulfo sialyl Lewis x on extended core1 O-glycans (PubMed:11439191).
