Beta-1,4-N-acetylgalactosaminyltransferase 3 (B4GALNT3)

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 Likely O-linked glycans.

Mediates the N,N'- diacetyllactosediamine formation on gastric mucosa.
