Structural highlights
FunctionMFNG_MOUSE Glycosyltransferase that initiates the elongation of O-linked fucose residues attached to EGF-like repeats in the extracellular domain of Notch molecules (PubMed:10935626). Modulates NOTCH1 activity by modifying O-fucose residues at specific EGF-like domains resulting in inhibition of NOTCH1 activation by JAG1 and enhancement of NOTCH1 activation by DLL1 via an increase in its binding to DLL1 (PubMed:10935626, PubMed:28089369).[1] [2] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedFringe proteins are beta1,3-N-acetylglucosaminyltransferases that modify Notch receptors, altering their ligand-binding specificity to regulate Notch signaling in development. We present the crystal structure of mouse Manic Fringe bound to UDP and manganese. The structure reveals amino acid residues involved in recognition of donor substrates and catalysis, and a putative binding pocket for acceptor substrates. Mutations of several invariant residues in this pocket impair Fringe activity in vivo.
