Galactoside 3(4)-L-fucosyltransferase is an enzyme that, in humans, is encoded by the FUT3 gene. [3] [4] [5]
The Lewis histo-blood group system comprises a set of fucosylated glycosphingolipids synthesized by exocrine epithelial cells and circulating in body fluids. These glycosphingolipids play essential roles in embryogenesis, tissue differentiation, tumor metastasis, inflammation, and bacterial adhesion. They are secondarily absorbed onto red blood cells, giving rise to the Lewis phenotype.
This gene is a member of the fucosyltransferase family, which catalyzes the addition of fucose to precursor polysaccharides during the final step of Lewis antigen biosynthesis. It encodes an enzyme with both alpha(1,3)-fucosyltransferase and alpha(1,4)-fucosyltransferase activities. Mutations in this gene are responsible for most Lewis antigen-negative phenotypes. Multiple alternatively spliced variants encoding the same protein have been identified for this gene. [5]
The Lewis antigen system is a human blood group system. It is based upon two genes on chromosome 19: FUT3, or Lewis gene; and FUT2, or Secretor gene. Both genes are expressed in glandular epithelia. FUT2 has a dominant allele which codes for an enzyme and a recessive allele which does not produce a functional enzyme. Similarly, FUT3 has a functional dominant allele (Le) and a non-functional recessive allele (le).

Galactoside 2-alpha-L-fucosyltransferase 2 is an enzyme that in humans is encoded by the FUT2 gene. It affects the secretor status of ABO antigens.
Alpha-(1,3)-fucosyltransferase is an enzyme that in humans is encoded by the FUT7 gene.
Galactoside 2-alpha-L-fucosyltransferase 1 is an enzyme that in humans is encoded by the FUT1 gene.
Beta-1,3-galactosyl-O-glycosyl-glycoprotein beta-1,6-N-acetylglucosaminyltransferase is an enzyme that in humans is encoded by the GCNT1 gene.
3-beta-glucuronosyltransferase 1 (B3GAT1) is an enzyme that in humans is encoded by the B3GAT1 gene, whose enzymatic activity creates the CD57 epitope on other cell surface proteins. In immunology, the CD57 antigen is also known as HNK1 or LEU7. It is expressed as a carbohydrate epitope that contains a sulfoglucuronyl residue in several adhesion molecules of the nervous system.
Alpha-(1,3)-fucosyltransferase is an enzyme that in humans is encoded by the FUT6 gene.
Alpha-(1,6)-fucosyltransferase is an enzyme that in humans is encoded by the FUT8 gene.
Alpha-(1,3)-fucosyltransferase is an enzyme that in humans is encoded by the FUT9 gene.
UDP-GlcNAc:betaGal beta-1,3-N-acetylglucosaminyltransferase 2 is an enzyme that in humans is encoded by the B3GNT2 gene.
Beta-1,4-galactosyltransferase 7 also known as galactosyltransferase I is an enzyme that in humans is encoded by the B4GALT7 gene. Galactosyltransferase I catalyzes the synthesis of the glycosaminoglycan-protein linkage in proteoglycans. Proteoglycans in turn are structural components of the extracellular matrix that is found between cells in connective tissues.
Prefoldin subunit 5 is a protein that in humans is encoded by the PFDN5 gene.
Lactosylceramide 4-alpha-galactosyltransferase is an enzyme that in humans is encoded by the A4GALT gene.
Alpha-N-acetylgalactosaminide alpha-2,6-sialyltransferase 1 is an enzyme that in humans is encoded by the ST6GALNAC1 gene. This enzyme adds a N-acetylneuraminic acid to an O-linked N-acetylgalactosamine (GalNAc) on a peptide/proteins with an α2-6 linkage to produce the sialyl-Tn antigen. It has been shown that the enzyme prefers threonine over serine containing GalNAc residues.
Histo-blood group ABO system transferase is an enzyme with glycosyltransferase activity, which is encoded by the ABO gene in humans. It is ubiquitously expressed in many tissues and cell types. ABO determines the ABO blood group of an individual by modifying the oligosaccharides on cell surface glycoproteins. Variations in the sequence of the protein between individuals determine the type of modification and the blood group. The ABO gene also contains one of 27 SNPs associated with increased risk of coronary artery disease.
Alpha-(1,3)-fucosyltransferase is an enzyme that in humans is encoded by the FUT5 gene.
Chondroitin sulfate N-acetylgalactosaminyltransferase 1 is an enzyme that in humans is encoded by the CSGALNACT1 gene.
Fucosyltransferase 4 , also known as FUT4, is an enzyme which in humans is encoded by the FUT4 gene.
