Alpha-(1,6)-fucosyltransferase, eukaryotic type (IPR015827)

Short name: Alpha1_6FUT_euk

Family relationships



Members of this group have enzymatic activity EC: They transfer fucose on glycoproteins to the innermost asparagine-linked N-acetylglucosamine of the chitobiose disaccharide-core unit [PMID: 10089206]. Core alpha 1,6-fucosylation is a conserved feature of animal N-linked oligosaccharides, being present in both invertebrates and vertebrates [PMID: 15604090].

All known fucosyltransferases are type II transmembrane proteins with four distinct domains: cytoplasmic, transmembrane, hypervariable, and catalytic. The catalytic domain resides in the luminal side of the trans-Golgi compartment [PMID: 2681181]. Members of this group share the conserved three alpha-6-motifs that are also present in the bacterial 6-alpha fucosyltransferases (IPR008716) [PMID: 9451017].

Disruption of the 6-alpha fucosyltransferase gene from a Chinese hamster ovary cell line has been shown to produce completely defucosylated recombinant antibodies [PMID: 15352059].

All members contain an SH3 domain (IPR001452) near the carboxyl end, but its function is unknown.
