Entrez Gene Summary for B4GALNT3 Gene

  • B4GALNT3 transfers N-acetylgalactosamine (GalNAc) onto glucosyl residues to form N,N-prime-diacetyllactosediamine (LacdiNAc, or LDN), a unique terminal structure of cell surface N-glycans (Ikehara et al., 2006 [PubMed 16728562]).[supplied by OMIM, Aug 2008]

GeneCards Summary for B4GALNT3 Gene

B4GALNT3 (Beta-1,4-N-Acetyl-Galactosaminyl Transferase 3) is a Protein Coding gene. GO annotations related to this gene include acetylgalactosaminyltransferase activity and N-acetyl-beta-glucosaminyl-glycoprotein 4-beta-N-acetylgalactosaminyltransferase activity. An important paralog of this gene is B4GALNT4.

UniProtKB/Swiss-Prot for B4GALNT3 Gene

  • Transfers N-acetylgalactosamine (GalNAc) from UDP-GalNAc to N-acetylglucosamine-beta-benzyl with a beta-1,4-linkage to form N,N-diacetyllactosediamine, GalNAc-beta-1,4-GlcNAc structures in N-linked glycans and probably O-linked glycans. Mediates the N,N-diacetyllactosediamine formation on gastric mucosa.
