This gene encodes a protein from the glycosyltransferase 32 family. The encoded enzyme catalyzes the transfer of N-acetylglucosamine to alpha-1,4-linked beta-galactose residues. This enzyme is required for type III mucin synthesis and it is largely associated with the Golgi apparatus membrane. The encoded protein appears to be expressed in adenocarcinoma cells of pancreatic, biliary tract and gastric cancers.[provided by RefSeq, Jan 2010]
