FUT9

FUT9

A gene on chromosome 6q16 that encodes an alpha-3-fucosyltransferase that catalyses the last step in Lewis antigen synthesis, adding  fucose to the precursor polysaccharide. FUT9 synthesises LeX oligosaccharide/CD15, which is expressed in organ buds during human embryogenesis.

Because other fucosyltransferases (FUT4, FUT6, FUT7, or FUT9) catalyze the Fuc [alpha]1,3 and [alpha]1,4 linkages to Gal residues of type 2 glycans, the [Le.sup.x], [sLe.sup.x], and [Le.sup.y] determinants are expressed in persons with mutated FUT3.
