Previous GeneCards Identifiers for B3GNT5 Gene
This gene encodes a member of the beta-1,3-N-acetylglucosaminyltransferase family. This enzyme is a type II membrane protein. It exhibits strong activity to transfer GlcNAc to glycolipid substrates and is identified as the most likely candidate for lactotriaosylceramide synthase. This enzyme is essential for the expression of Lewis X epitopes on glycolipids. [provided by RefSeq, Jul 2008]
GeneCards Summary for B3GNT5 Gene
B3GNT5 (UDP-GlcNAc:BetaGal Beta-1,3-N-Acetylglucosaminyltransferase 5) is a Protein Coding gene. Diseases associated with B3GNT5 include Salt And Pepper Syndrome. Among its related pathways are Metabolism of proteins and Glycosphingolipid biosynthesis - lacto and neolacto series. Gene Ontology (GO) annotations related to this gene include oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen and beta-galactosyl-N-acetylglucosaminylgalactosylglucosyl-ceramide beta-1,3-acetylglucosaminyltransferase activity. An important paralog of this gene is B3GNT6.
UniProtKB/Swiss-Prot Summary for B3GNT5 Gene
Beta-1,3-N-acetylglucosaminyltransferase that plays a key role in the synthesis of lacto- or neolacto-series carbohydrate chains on glycolipids, notably by participating in biosynthesis of HNK-1 and Lewis X carbohydrate structures. Has strong activity toward lactosylceramide (LacCer) and neolactotetraosylceramide (nLc(4)Cer; paragloboside), resulting in the synthesis of Lc(3)Cer and neolactopentaosylceramide (nLc(5)Cer), respectively. Probably plays a central role in regulating neolacto-series glycolipid synthesis during embryonic development.
