basic FUNCTION	may be involved in blood group lewis determination
	FUT3 is the key enzyme driving sialyl Lewis A (sLe(a)) biosynthesis in human intestinal epithelial cells (IECs)
	selection of mutualistic microorganisms of the intestinal microbiota is controlled by the FUT2 and FUT3 genes that encode fucosyltransferases, enzymes responsible for the synthesis of fucosylated glycan structures of mucins and milk oligosaccharides
	FUT3/FUT6 has an essential role in cancer cell adhesion to endothelial cells by upregulation of sialyl Lewis antigens and also by enhancement of cancer cell migration through TGFB1-mediated EMT
