FUT3, 35-361aa, Human, His tag, E.coli

Fucosyltransferase 3, also known as FUT3, may catalyze alpha-1,3 and alpha-1,4 glycosidic linkages involved in the expression of Vim-2, Lewis A, Lewis B, sialyl Lewis X and Lewis X/SSEA-1 antigens. This protein may be involved in blood group Lewis determination; Lewis-positive (Le+) individuals have an active enzyme while Lewis-negative (Le-) individuals have an inactive enzyme. Also acts on the corresponding 1,4-galactosyl derivative, forming 1,3-L-fucosyl links. Recombinant human FUT3 protein, fused to His-tag at N-terminus, was expressed in E.coli.
