Anti-GALNT15 antibodies are used in the immunodetection of the protein polypeptide N-acetylgalactosaminyltransferase 15. In humans, the canonical protein has a reported length of 639 amino acid residues and a mass of 73.1 kDa. Its subcellular localization is in the Golgi. It is widely expressed across many tissue types. A member of the Glycosyltransferase 2 protein family, GALNT15 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. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase-like protein 2, UDP-N-acetyl-alpha-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase 15, and UDP-GalNAc transferase T15. GALNT15 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some GALNT15 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.
