Function
Mediates the transfer of fucose to the terminal galactose on glycan chains of cell surface glycoproteins and glycolipids (PubMed:11323419, PubMed:27161092). The resulting epitope plays a role in cell-cell interaction including host-microbe interaction (PubMed:19706747, PubMed:27161092). Mediates interaction with intestinal microbiota influencing its composition (PubMed:19706747, PubMed:27161092). Creates a soluble precursor oligosaccharide FuC-alpha ((1,2)Galbeta-) called the H antigen, which is an essential substrate for the final step in the blood group antigen synthesis pathway (PubMed:11323419).
