Anti-B3GNT5 antibodies are used in the immunodetection of the protein UDP-GlcNAc:betaGal beta-1,3-N-acetylglucosaminyltransferase 5. In humans, the canonical protein has a reported length of 378 amino acid residues and a mass of 44.1 kDa. Its subcellular localization is in the Golgi. It is widely expressed across many tissue types. A member of the Glycosyltransferase 31 protein family, B3GNT5 is a reported 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. Synonyms for this target antigen include BGnT-5, beta 1,3 N-acetyglucosaminyltransferase Lc3 synthase, beta-1,3-Gn-T5, beta-1,3-N-acetylglucosaminyltransferase 5, and lactosylceramide 1,3-N-acetyl-beta-D-glucosaminyltransferase. B3GNT5 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some B3GNT5 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
