CC -!- FUNCTION: Catalyzes the transfer of L-fucose, from a guanosine
CC diphosphate-beta-L-fucose, to the terminal galactose on both O- and N-
CC linked glycans chains of cell surface glycoproteins and glycolipids and
CC the resulting epitope regulates several processes such as cell-cell
CC interaction including host-microbe interaction, cell surface expression
CC and cell proliferation. Preferentially fucosylates gangliosides GA1 and
CC GM1 in the antrum, cecum and colon and in the female reproductive
CC organs. Fucosylated host glycoproteins or glycolipids mediate
CC interaction with intestinal microbiota influencing its composition.
CC Creates a soluble precursor oligosaccharide FuC-alpha ((1,2)Galbeta-)
CC called the H antigen which is an essential substrate for the final step
CC in the soluble ABO blood group antigen synthesis pathway.
CC {ECO:0000250|UniProtKB:Q9JL27}.
