Anti-GALNT5 antibodies are used in the immunodetection of the protein polypeptide N-acetylgalactosaminyltransferase 5. In humans, the canonical protein has a reported length of 940 amino acid residues and a mass of 106.3 kDa. Its subcellular localization is in the Golgi. It is notably expressed in many tissues, such as the appendix and colon. A member of the Glycosyltransferase 2 protein family, GALNT5 is known to catalyze the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. Synonyms for this target antigen include GALNACT5, UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 5, UDP-N-acetyl-alpha-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase 5 (GalNAc-T5), and GALNAC-T5. GALNT5 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is a widely used application for the GALNT5 antibodies listed below. In addition, Immunohistochemistry is also a common application.
