(57) [summary] The present invention provides a useful glycoprotein having a human-type sugar chain. The invention relates to a method for producing a glycoprotein having a human-type sugar chain, into plant cells, by introducing a gene of a gene and a heterologous glycoprotein glycosyltransferases, obtaining a transformed plant cell, and obtained comprising the step of culturing a transformed plant cells. The glycosyltransferase is capable of performing a transfer reaction of a galactose residue to a non-reducing terminal acetylglucosamine residues. Glycoprotein with the human-type sugar chain comprises a core sugar chain and an outer sugar chain, this core sugar chain comprises a plurality of mannose and acetylglucosamine, and this outer sugar chain, the terminal sugar with a non-reducing terminal galactose It comprises a chain portion, with a straight chain structure or a branched structure. Glycoprotein having the human-type sugar chains, because it contains no fucose or xylose, show no antigenicity against humans.
