Polypeptide GalNAc Transferase 12/GALNT12 Proteins and Enzymes

GALNT12, also known as Polypeptide N-acetylgalactosaminyltransferase 12, has a 581 amino acid long isoform that is 67 kDa and a short 272 amino acid isoform that is 32 kDa, plays role in catalyzing the initial reaction in O-linked oligosaccharide biosynthesis, and the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor; displays activity toward non-glycosylated peptides such as Muc5AC, Muc1a and EA2, Gal-NAc-Muc5AC glycopeptide; and ...
