Catalyzes the transfer of L-fucose, from a guanosine diphosphate-beta-L-fucose, to the terminal galactose on both O- and N-linked glycans chains of cell surface glycoproteins and glycolipids and the resulting epitope regulates several processes such as cell-cell interaction including host-microbe interaction, cell surface expression and cell proliferation (PubMed:11341836, PubMed:11179967). Preferentially fucosylates gangliosides GA1 and GM1 in the antrum, cecum and colon and in the female reproductive organs. Fucosylated host glycoproteins or glycolipids mediate interaction with intestinal microbiota influencing its composition (By similarity). 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 soluble ABO blood group antigen synthesis pathway (PubMed:11179967). a beta-D-galactosyl-(1->3)-N-acetyl-beta-D-glucosaminyl derivative + GDP-beta-L-fucose = an alpha-L-Fuc-(1->2)-beta-D-Gal-(1->3)-beta-D-GlcNAc derivative + GDP + H(+) a beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl derivative + GDP-beta-L-fucose = an alpha-L-Fuc-(1->2)-beta-D-Gal-(1->4)-beta-D-GlcNAc derivative + GDP + H(+) ganglioside GM1 (d18:1(4E)) + GDP-beta-L-fucose = gangliosideFuc-GM1 (d18:1(4E)) + GDP + H(+) GDP-beta-L-fucose + globoside GalGb4Cer (d18:1(4E)) = GDP + globoside Globo-H (d18:1(4E)) + H(+) a neolactoside nLc4Cer + GDP-beta-L-fucose = a neolactoside IV(2)-alpha-Fuc-nLc4Cer + GDP + H(+) a neolactoside nLc4Cer(d18:1(4E)) + GDP-beta-L-fucose = a neolactoside IV(2)-alpha-Fuc-nLc4Cer(d18:1(4E)) + GDP + H(+) ganglioside GM1 + GDP-beta-L-fucose = ganglioside Fuc-GM1 + GDP + H(+) ganglioside GA1 + GDP-beta-L-fucose = ganglioside Fuc-GA1 + GDP + H(+) GDP-beta-L-fucose + Lc4Cer = alpha-L-fucosyl-(1->2)-beta-D-galactosyl-(1->3)-N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D-galactosyl-(1->4)-beta-D-glucosyl-(1<->1')-ceramide + GDP + H(+) a beta-D-Gal-(1->3)-beta-D-GlcNAc-(1->3)-beta-D-Gal-(1->4)-beta-D-Glc-(1<->1')-Cer(d18:1(4E)) + GDP-beta-L-fucose = alpha-L-fucosyl-(1->2)- beta-D-galactosyl-(1->3)-N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D-galactosyl-(1->4)-beta-D-glucosyl-(1<->1')-N-acylsphing-4-enine + GDP + H(+) ganglioside GD1b + GDP-beta-L-fucose = ganglioside Fuc-GD1b + GDP + H(+) a lactoside III(4)-a-Fuc-Lc4Cer + GDP-beta-L-fucose = a lactoside IV(2),III(4)-a-[Fuc]2-Lc4Cer + GDP + H(+) beta-D-galactosyl-(1->3)-N-acetyl-D-galactosamine + GDP-beta-L-fucose = alpha-L-fucosyl-(1->2)-beta-D-galactosyl-(1->3)-N-acetyl-D-galactosamine + GDP + H(+) Protein modification; protein glycosylation. Membrane-bound form in trans cisternae of Golgi. Specifically expressed in gut. In rat, there are three genes (Fut1/Fta, Fut2/Ftb and Ftc) which encode galactoside 2-L-fucosyltransferase. They are expressed in a tissue-specific manner and Ftc may have no enzymatic activity. Belongs to the glycosyltransferase 11 family.
