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 glyc...
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 (PubMed:19088067). Involved in biosynthesis of Lewis X-carrying biantennary N-glycans that regulate neuron stem cell self-renewal during brain development (By similarity). {ECO:0000250|UniProtKB:Q5F2L2, ECO:0000269|PubMed:19088067}.; FUNCTION: [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. {ECO:0000269|PubMed:19088067}.; FUNCTION: [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. {ECO:0000269|PubMed:19088067}.; FUNCTION: [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. {ECO:0000269|PubMed:19088067}.
