Anti-GALNT17 antibodies are used in the immunodetection of the protein polypeptide N-acetylgalactosaminyltransferase 17. In humans, the canonical protein has a reported length of 598 amino acid residues and a mass of 67.8 kDa. Its subcellular localization is in the Golgi. It is reported to be highly expressed in the brain and heart. A member of the Glycosyltransferase 2 protein family, GALNT17 is believed 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 3, UDP-N-acetyl-alpha-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase 16, and UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase-like 3. GALNT17 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. ELISA, Western Blot, and Immunohistochemistry are common applications for GALNT17 antibodies.
