Function
Predominantly fucosylates the innermost N-acetyl glucosamine (GlcNAc) residue in biantennary N-glycan acceptors. Postulated to generate core alpha(1->3)-fucose epitope within the chitobiose unit of biantennary N-glycans, providing for a recognition signal to reorient aberrantly folded glycoproteins for degradation . Involved in biosynthesis of Lewis X-carrying biantennary N-glycans that regulate neuron stem cell self-renewal during brain development (By similarity).; [Isoform 1]: Catalyzes the transfer of fucosyl moiety from GDP-beta-L-fucose to the innermost GlcNAc residue in biantennary N-glycan acceptors. Does not fucosylate GlcNAc within type 2 lactosamine unit.; [Isoform 4]: Catalyzes the transfer of fucosyl moiety from GDP-beta-L-fucose to the innermost GlcNAc residue in biantennary N-glycan acceptors. Does not fucosylate GlcNAc within type 2 lactosamine unit.; [Isoform 5]: Catalyzes the transfer of fucosyl moiety from GDP-beta-L-fucose to the innermost GlcNAc residue in biantennary N-glycan acceptors. Does not fucosylate GlcNAc within type 2 lactosamine unit.
