. "SEQUENCE 331 AA; 36424 MW; 986270FFA7C13573 CRC64;"^^ . "FUNCTION: Glycosyltransferase that initiates the elongation of O- linked fucose residues attached to EGF-like repeats in the extracellular domain of Notch molecules. May be involved in limb formation and in neurogenesis (By similarity). CATALYTIC ACTIVITY: Transfers a beta-D-GlcNAc residue from UDP-D- GlcNAc to the fucose residue of a fucosylated protein acceptor. COFACTOR: Manganese (By similarity). SUBCELLULAR LOCATION: Golgi apparatus membrane; Single-pass type II membrane protein (Potential). SIMILARITY: Belongs to the glycosyltransferase 31 family.
