Synonyms
  1. GalNAc-T4
  2. Polypeptide GalNAc transferase 4
  3. Protein-UDP acetylgalactosaminyltransferase 4
  4. UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 4

Gene Name GALNT4
Protein Type Enzyme
Biological Properties
General Function Involved in polypeptide N-acetylgalactosaminyltransfera
Specific Function Catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. Has a highest activity toward Muc7, EA2 and Muc2, with a lowest activity than GALNT2. Glycosylates 'Thr-57' of SELPLG.
