This gene encodes polypeptide N-acetylgalactosaminyltransferase 2, a member of the GalNAc-transferases family. This family transfers an N-acetyl galactosamine to the hydroxyl group of a serine or threonine residue in the first step of O-linked oligosaccharide biosynthesis. The localization site of this particular enzyme is preponderantly the trans-Golgi.^[8] Individual GalNAc-transferases have distinct activities, and initiation of O-glycosylation in a cell is regulated by a repertoire of GalNAc-transferases.^[7]
