Protein
Glycoprotein-N-acetylgalactosamine 3-beta-galactosyltransferase 1-B
Function
Glycosyltransferase that generates the core 1 O-glycan Gal-beta1-3GalNAc-alpha1-Ser/Thr (T antigen), which is a precursor for many extended O-glycans in glycoproteins.
Similarity
Belongs to the glycosyltransferase 31 family. Beta3-Gal-T subfamily.
