Polypeptide N-Acetylgalactosaminyltransferase 10; UDP-N-Acetyl-Alpha-D-Galactosamine:Polypeptide N-Acetylgalactosaminyltransferase 10 (GalNAc-T10); UDP-GalNAc:Polypeptide N-Acetylgalactosaminyltransferase 10; Polypeptide GalNAc Transferase 10; EC 2.4.1.41; Protein-UDP Acetylgalactosaminyltransferase 10; GalNAc Transferase 10

This gene encodes a member of the GalNAc polypeptide N-acetylgalactosaminyltransferases. These enzymes catalyze the first step in the synthesis of mucin-type oligosaccharides. These proteins transfer GalNAc from UDP-GalNAc to either serine or threonine residues of polypeptide acceptors. The protein encoded by this locus may have increased catalytic activity toward glycosylated peptides compared to activity toward non-glycosylated peptides.
