This enzyme catalyzes the GalNAc transfer from UDP-GalNAc to Ser or Thr residue in the protein. The product is GalNAc-alpha-O-Ser/Thr structure, so-called Tn-antigen, which is the base structure of mucin type O-glycan. The acceptor substrate (protein) is typically Mucin. GALNT12 is the twelfth member of this enzyme family. This isozyme is expressed in digestive organ.
