ABSTRACT:
The present invention discloses a method for modulating the production of a protein from a polynucleotide in a CHO cell by replacing at least one codon of the polynucleotide with a synonymous codon that has a higher or lower translation efficiency in the CHO cell than the codon it replaces, or by introducing into the CHO cell a polynucleotide that codes for an iso-tRNA which limits the rate of production of the polypeptide and which corresponds to a codon of the first polynucleotide. The present invention also discloses the use of a protein-encoding polynucleotide whose codon composition has been modified for enhanced production of the protein in CHO cells.
