GCNT3 is a glucosaminyl (N-acetyl) transferase 3, mucin type, which transfers GlcNAc from UDP-GlcNAc to the C6 position of GalNAc in core 1 and core 3 O-glycan structures, synthesizing core 2 and core 4 structures, respectively. GCNT3 also has a weak activity to form I-branching structure in vitro and on cell surface. GCNT3 is also known as C2GNT2, C2/4GNT, or C2GNT-M.
