Anti-GCNT1 antibodies are used in the immunodetection of the protein glucosaminyl (N-acetyl) transferase 1. In humans, the canonical protein has a reported length of 428 amino acid residues and a mass of 49.8 kDa. Its subcellular localization is in the Golgi. It is reported to be highly expressed in activated T-lymphocytes and myeloid cells. A member of the Glycosyltransferase 14 protein family, GCNT1 is a reported glycosyltransferase that catalyzes the transfer of an N-acetylglucosamine (GlcNAc) moiety in beta1-6 linkage from UDP-GlcNAc onto mucin-type core 1 O-glycan to form the branched mucin-type core 2 O-glycan. Synonyms for this target antigen include C2GNT-L, C2GNT1, C2GlcNAcT, G6NT, NACGT2, and C2GNT. GCNT1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some GCNT1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
