B4GALNT2 (beta-1,4-N-acetyl-galactosaminyltransferase 2)

Gene

• Entrez ID: 124872
• Gene name: Beta-1,4-N-acetyl-galactosaminyltransferase 2
• Gene symbol: B4GALNT2
• Synonyms: B4GALT, GALGT2
• Chromosome: 17
• Chromosome location: 17q21.32
• Summary: B4GALNT2 catalyzes the last step in the biosynthesis of the human Sd(a) antigen through the addition of an N-acetylgalactosamine residue via a beta-1,4 linkage to a subterminal galactose residue substituted with an alpha-2,3-linked sialic acid. B4GALNT2 also catalyzes the last step in the biosynthesis of the Cad antigen (Montiel et al., 2003 [PubMed 12678917]).[supplied by OMIM, Mar 2008]

Protein

• UniProt ID: Q8NHY0
• Protein name: Beta-1,4 N-acetylgalactosaminyltransferase 2 (EC 2.4.1.-) (Sd(a) beta-1,4-GalNAc transferase) (UDP-GalNAc:Neu5Aca2-3Galb-R b1,4-N-acetylgalactosaminyltransferase)
• Protein function: Involved in the synthesis of the Sd(a) antigen (Sia-alpha2,3-[GalNAc-beta1,4]Gal-beta1,4-GlcNAc), a carbohydrate determinant expressed on erythrocytes, the colonic mucosa and other tissues. Transfers a beta-1,4-linked GalNAc to the galactose residue of an alpha-2,3-sialylated chain.
