CC -!- FUNCTION: Catalyzes the transfer of L-fucose, from a guanosine
CC diphosphate-beta-L-fucose, to the terminal galactose residue of
CC glycoconjugates through an alpha(1,2) linkage leading to H antigen
CC synthesis that is an intermediate substrate in the synthesis of ABO
CC blood group antigens. H antigen is essential for maturation of the
CC glomerular layer of the main olfactory bulb, in cell migration and
CC early cell-cell contacts during tumor associated angiogenesis (By
CC similarity). Preferentially fucosylates soluble lactose and to a lesser
CC extent fucosylates glycolipids gangliosides GA1 and GM1a (By
CC similarity). {ECO:0000250|UniProtKB:O09160,
CC ECO:0000250|UniProtKB:P19526}.
