Methods for improving recombinant protein expression
Disclosed are materials and methods which allow for increased expression of a transfected gene of interest in a recombinant host cell. The method involves culturing the host cell comprising a first heterologous polynucleotide sequence encoding the heterologous protein under conditions that allow for protein expression, the first polynucleotide encoded on a vector, the host cell further comprising a second polynucleotide sequence having a protein coding sequence for a selectable marker protein, the second polynucleotide having a sequence modification compared to a wild-type polynucleotide encoding the selectable marker protein, the sequence modification reducing translation efficiency of mRNA encoded by the second polynucleotide, the second polynucleotide having the sequence modification and the wild-type polynucleotide encoding identical amino acid sequences for the selectable marker protein. The method provides means of increasing selection pressure on a vector thereby increasing vector-associated heterologous protein expression.
