Function
Involved in the fucosylation of N-glycans (PubMed:15364955, PubMed:17369288, PubMed:23754284, PubMed:26538210, PubMed:26002521). Preferentially catalyzes the addition of fucose in alpha 1-3 linkage to the distal GlcNAc residue in N-glycans (PubMed:23754284). Catalyzes the transfer of fucose to Gal-beta-1-4-GlcNAc-alpha-pNP (LN-pNP) and Gal-beta-1-4-GlcNAc-beta-1-3-Gal-beta-1-4-Glc (LNnT) (PubMed:17369288). Unlike alpha-(1,3)-fucosyltransferase fut-1, does not transfer fucose to Man-alpha-1-3-(Man-alpha-1-6)-Man-beta-1-4-GlcNAc-beta-1-4-GlcNAc-beta-1-Asn (M3), Man-alpha-1-3-(Man-alpha-1-6)-Man-beta-1-4-GlcNAc-beta-1-4-(Fuc-alpha-1-6)-GlcNAc-beta-1-Asn (M3F6) and GlcNAc-beta-1-2-Man-alpha-1-3-(GlcNAc-beta-1-2-Man-alpha-1-6)-Man-beta-1-4-GlcNAc-beta-1-4(Fuc-alpha-1-6)-GlcNAc-beta-1-Asn (GnM3F6) (PubMed:17369288).
