Abstract

The present invention is based on the finding that the combination of a specific 5′UTR polynucleotide sequence (see SEQ ID NO 1) and the hCD33 secretory leader sequence in an expression cassette for expressing a polypeptide of interest results in a surprisingly better expression level of the polypeptide of interest compared to prior art expression cassettes. Based on this finding, the present invention inter alia provides novel expression cassettes, expression vectors and methods for producing a polypeptide of interest with high yield.
