Anti-LFNG antibodies are used in the immunodetection of the protein LFNG O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase. In humans, the canonical protein has a reported length of 379 amino acid residues and a mass of 41.8 kDa. Its subcellular localization is in the Golgi. Up to 4 different isoforms have been reported for this protein. It is notably expressed in many tissues, such as the adrenal gland and cerebral cortex. A member of the Glycosyltransferase 31 protein family, LFNG 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 SCDO3 and beta-1,3-N-acetylglucosaminyltransferase lunatic fringe. LFNG gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some LFNG antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
