Glycosylation of Pre-Notch by Fringe

Mouse Notch1 fragment containing EGF repeats 19-23, with a conserved O-fucosylation site in EGF repeat 20, was shown to be a direct target of manic fringe (Mfng) when both mouse Notch1 fragment and Mfng were exogenously expressed in a Chinese hamster ovary cell line (Moloney et al. 2000). Lunatic fringe was shown to directly act on Notch1 to modulate its signaling (Hicks et al. 2000). Fringe enzymes include lunatic fringe (Lfng), manic fringe (Mfng) and radical fringe (Rfng) in mammals. Fringe enzymes localize to Golgi membrane and function by extending O-fucosyl residues on fucosylated peptides, including Notch, by transferring a beta 1,3-linked N-acetyl glucosaminyl group. Since the exact preference, if any, of fringe enzymes for Notch O-fucose sites is not known, the extension of an O-fucosyl residue at unknown position is shown.
