Anti-MGAT2 antibodies are used in the immunodetection of the protein alpha-1,6-mannosyl-glycoprotein 2-beta-N-acetylglucosaminyltransferase. In humans, the canonical protein has a reported length of 447 amino acid residues and a mass of 51.6 kDa. Its subcellular localization is in the Golgi. It is notably widely expressed in many tissue types. A member of the Glycosyltransferase 16 (GT16) protein family, MGAT2 is known to play an important role in protein N-glycosylation. Post-translational modifications have been described, including glycosylation. The MGAT2 gene has been associated with the disease, Congenital disorder of glycosylation. Synonyms for this target antigen include CDGS2, GLCNACTII, GNT-II, GNT2, and CDG2A. MGAT2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
