Anti-GALNT13 antibodies are used in the immunodetection of the protein polypeptide N-acetylgalactosaminyltransferase 13. In humans, the canonical protein has a reported length of 556 amino acid residues and a mass of 64.1 kDa. Its subcellular localization is in the Golgi. Up to 3 different isoforms have been reported for this protein. It is notably expressed in neuronal cells. A member of the Glycosyltransferase 2 protein family, GALNT13 is known to catalyze the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine (GalNAc) residue from UDP-GalNAc to a serine or threonine residue on the protein receptor. Synonyms for this target antigen include UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 13, UDP-N-acetyl-alpha-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase 13 (GalNAc-T13), polypeptide GalNAc transferase 13, and GalNAc transferase 13. GALNT13 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the GALNT13 antibodies listed below. ELISA and Immunofluorescence are also common applications.
