FUT3

Metabolic System · Glycosylation & Glycan Biosynthesis

How can FUT3 influence the Lewis blood-group system?

FUT3 makes an enzyme that adds fucose sugars to selected molecules. These modifications help form Lewis antigens, which can circulate in body fluids and become associated with red blood cells.

Common Gene Name: fucosyltransferase 3 (Lewis blood group)
NCBI Gene ID: 2525
Chromosome: 19
