Anti-GCNT4 antibodies are used in the immunodetection of the protein glucosaminyl (N-acetyl) transferase 4. In humans, the canonical protein has a reported length of 453 amino acid residues and a mass of 53.1 kDa. Its subcellular localization is in the Golgi. It is reported to be highly expressed in the thymus. A member of the Glycosyltransferase 14 protein family, GCNT4 is a reported glycosyltransferase that mediates core 2 O-glycan branching, an important step in mucin-type biosynthesis. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include LINC01336, beta-1,3-galactosyl-O-glycosyl-glycoprotein beta-1,6-N-acetylglucosaminyltransferase 4, core 2 beta-1,6-N-acetylglucosaminyltransferase 3, and C2GNT3. GCNT4 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Western Blot is a widely used application for the GCNT4 antibodies listed below. In addition, Immunofluorescence is also a common application.
