Anti-GALNT12 antibodies are used in the immunodetection of the protein polypeptide N-acetylgalactosaminyltransferase 12. In humans, the canonical protein has a reported length of 581 amino acid residues and a mass of 66.9 kDa. Its subcellular localization is in the Golgi. Up to 2 different isoforms have been reported for this protein. It is found to be widely expressed at different levels of expression. A member of the Glycosyltransferase 2 protein family, GALNT12 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. The GALNT12 gene has been associated with the disease, Colorectal cancer. Synonyms for this target antigen include UDP-N-acetyl-alpha-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase 12 (GalNAc-T12), colorectal cancer, susceptibility to 1, polypeptide GalNAc transferase 12, and UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 12. Some GALNT12 antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Immunohistochemistry experiments, among other applications.
