摘要:
The present invention provides a recombinant vector pBI-3D-hGalT or pBI-35S-hGalT containing a human β1,4-galactosyltransferase gene; a cell line transformed with a recombinant vector pMYN414 containing a cytotoxic T-lymphocyte anti-gen A-immunoglobulin (CTLA4Ig) fusion protein gene and the recombinant vector pBI-3D-hGalT or pBI-355-hGalT; and a method for producing a plant-derived recombinant human CTLA4Ig (CTLA4Igp) fusion protein with a human glycan structure using the same. The plant cell-derived recombinant human CTLA4Ig fusion protein (CTLA4Igp), which has a human glycan structure and is produced according to the present invention, exhibits an improved in vivo half life as compared to conventional plant-derived proteins, due to the presence of a human-like glycan structure. Consequently, the present invention using the plant expression system enables low-cost mass production of a CTLA4Igp fusion protein having an immunosuppressive activity comparable to that of the CTLA4IgM fusion protein expressed in conventional animal cell expression systems.

Provided is a method for producing a target protein via cultivation of transgenic plant cells comprising a promoter capable of expressing the protein under sugar-free conditions or in response to the depletion of sugar and a gene encoding the target protein, without exchange of a cell growth medium with a sugar-depleted medium. The method comprises 1) culturing transgenic plant cells in a sugar-rich medium to grow plant cells; and 2) culturing the transgenic plant cells with addition of an amino acid mixture to the culture of Step 1 without exchange of a cell growth medium with a sugar-depleted medium, thereby expressing a target protein. The method of the present invention enables commercial-scale production of recombinant proteins via establishment of optimized culture conditions by addition of an amino acid mixture to induce protein expression without exchange of a cell growth medium with a sugar-free medium, and addition of pyruvic acid during the induction period of protein expression to thereby enhance the production yield of target proteins.
