B4GN3_HUMAN Protein

Name Beta-1,4-N-acetylgalactosaminyltransferase 3
Description 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.
UniProt ID Q6L9W6
Gene B4GALNT3
