Abstract
The invention provides a genetically modified Chinese Hamster Ovary (CHO) cell for production of a recombinant polypeptide, comprising a transgene encoding a CHO-derived signal peptide fused to a recombinant polypeptide, wherein said signal peptide is capable of directing co-translational transport of said polypeptide in the cell resulting in enhanced levels of polypeptide secretion. The invention further provides a method for producing a recombinant polypeptide by using the genetically modified CHO cell. The invention further provides for the use of a CHO-derived signal peptide and a transgene encoding said signal peptide to enhance production of extracellular recombinant polypeptide by a genetically modified CHO cell.
