Listed are ELISA Kits for the detection of GALNT20, an alias name of polypeptide N-acetylgalactosaminyltransferase 17. The human protein, encoded by the gene GALNT17, is 598 amino acid residues long and has a mass of 67,751 daltons. It is an enzyme of the polypeptide N-acetylgalactosaminyltransferase class and is a member of the Glycosyltransferase 2 family, GalNAc-T subfamily. The gene is associated with Williams-Beuren syndrome (WBS). This target may also be known as: UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase-like protein 3, galNAc-T-like protein 3, polypeptide N-acetylgalactosaminyltransferase WBSCR17, and polypeptide N-acetylgalactosaminyltransferase-like 3.
