Anti-MFNG antibodies are used in the immunodetection of the protein MFNG O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase. In humans, the canonical protein has a reported length of 321 amino acid residues and a mass of 36.2 kDa. Its subcellular localization is in the Golgi. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Glycosyltransferase 31 protein family, MFNG is a reported glycosyltransferase that initiates the elongation of O-linked fucose residues attached to EGF-like repeats in the extracellular domain of Notch molecules. Synonyms for this target antigen include O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase, and beta-1,3-N-acetylglucosaminyltransferase manic fringe. MFNG gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Some MFNG antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
