Fucosyltransferase 4; Galactoside 3-L-Fucosyltransferase; Alpha (1,3) Fucosyltransferase, Myeloid-Specific; ELAM-1 Ligand Fucosyltransferase; ELAM Ligand Fucosyltransferase; Fucosyltransferase IV; FUC-TIV; FucT-IV; FCT3A; ELFT; Stage-Specific Embryonic Antigen 1

The product of this gene transfers fucose to N-acetyllactosamine polysaccharides to generate fucosylated carbohydrate structures. It catalyzes the synthesis of the non-sialylated antigen, Lewis x (CD15).
