The present invention relates to a cell into which an RNA capable of suppressing the function of an enzyme catalyzing a reaction which converts GDP-mannose into GDP-4-keto,6-deoxy-GDP-mannose is introduced; a process for producing a glycoprotein using the cell; a cell into which an RNA capable of suppressing the function of an enzyme relating to modification of a sugar chain in which 1-position of fucose is bound to 6-position of N-acetylglucosamine in the reducing end through ±-bond in the complex type N-glycoside-linked sugar chain, and an RNA capable of suppressing the function of an enzyme protein relating to synthesis of an intracellular sugar nucleotide, GDP-fucose, or an RNA capable of suppressing the function of a protein relating to transport of an intracellular sugar nucleotide, GDP-fucose, to the Golgi body are introduced; a process for producing a glycoprotein composition using the cell; and the like.
