Background: Glucosaminyl (N-acetyl) Transferase 1/GCNT1

Mucin-type O-glycans are initiated with an O-GalNAc attachment to a serine or threonine in a polypeptide. The O-GalNAc residues are subsequently extended by various glycosyltransferases resulting in different types of O-glycans. Most O-glycans contain the core 1 structure, Gal beta 1-3GalNAc. Glucosaminyl (N-acetyl) Transferase 1 (GCNT1) converts the core 1 O-glycan to core 2 O-glycan, Gal beta 1-3(GlcNAc beta 1-6)GalNAc, via the addition of a GlcNAc residue (1, 2). Various ligand carbohydrates can be formed from core 2 branched oligosaccharides. For example, sialyl Le^x in mucin‑type glycoproteins of blood cells can be formed from core 2 branched oligosaccharides (3, 4). The expression of GCNT1 was found to be associated with the progression of various types of cancer (5, 6, 7). The enzymatic activity of the recombinant GCNT1 is measured using a phosphatase-coupled method (8).
