Selectively catalyzes the addition of fucose in alpha 1-2 linkage to Gal-beta-(1->4)-Xyl-beta-R, Gal-beta-(1->6)-GlcNAc-R, Gal-beta-(1->3)-Gal-beta-(1->4)-Glc and Gal-beta-(1->3)-Gal-beta-(1->4)-Xyl-R acceptors but not Gal-beta-(1->3)-GlcNAc-beta-(1->3)-Gal-beta-(1->4)-Glc. Unlike in mammals, unable to fucosylate Gal-beta-(1->4)-Glc-beta-R. Protein modification; protein glycosylation. Expression is restricted to the 20 intestinal cells in larvae and adult. Expressed throughout development and in adult. Belongs to the glycosyltransferase 11 family.
