Polypeptide N-Acetylgalactosaminyltransferase 13; Polypeptide GalNAc Transferase 13; UDP-N-Acetyl-Alpha-D-Galactosamine:Polypeptide N-Acetylgalactosaminyltransferase 13 (GalNAc-T13); UDP-GalNAc:Polypeptide N-Acetylgalactosaminyltransferase 13; Protein-UDP Acetylgalactosaminyltransferase 13; Pp-GaNTase 13; EC 2.4.1.41; GalNAc-T13; Polypeptide N-Acetylgalactosaminyltransferase 13 Variant DeltaEx6 DeltaEx8 Delta39bpEx9

The GALNT13 protein is a member of the UDP-N-acetyl-alpha-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase (GalNAcT; EC 2.4.1.41) family, which initiate O-linked glycosylation of mucins (see MUC3A, MIM 158371) by the initial transfer of N-acetylgalactosamine (GalNAc) with an alpha-linkage to a serine or threonine residue.
