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 probably O-linked glycans. Mediates the N,N'-diacetyllactosediamine formation on gastric mucosa. Belongs to the chondroitin N-acetylgalactosaminyltransferase family. Highly expressed in testis, colon and stomach. Weakly expressed in other tissues. Note: This description may include information from UniProtKB.
