    • It is intended to provide a gene encoding fucose transporter; a fucose transporter polypeptide; a method of screening a compound binding to the fucose transporter and a compound inhibiting the fucose-transporting activity; a cell suffering from the inhibition of fucose transporter function; and a cell suffering from the inhibition of fucose transporter expression. It is also intended to provide a method of producing a recombinant protein characterized by comprising lessening fucose contained in Golgi bodies in a host cell; a method of inhibiting the attachment of fucose to a protein characterized by comprising, in the production of a recombinant protein with the use of a host cell, lessening fucose contained in Golgi bodies in the host cell; a method of elevating the cytotoxic activity of an antibody characterized by comprising constructing the antibody in a cell in which fucose contained in Golgi bodies is lessened; and a cell having Golgi bodies in which fucose contained therein is lessened.
