Anti-RFNG antibodies are used in the immunodetection of the protein RFNG O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase. In humans, the canonical protein has a reported length of 331 amino acid residues and a mass of 36.4 kDa. Its subcellular localization is in the Golgi. A member of the Glycosyltransferase 31 protein family, RFNG 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. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase, radical fringe homolog, and beta-1,3-N-acetylglucosaminyltransferase radical fringe. RFNG gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is a widely used application for the RFNG antibodies listed below. In addition, ELISA is also a common application.
