Abstract
The present invention provides polynucleotide vectors for high expression of heterologous genes. Some vectors further comprise novel transposons and transposases that further improve expression. Further disclosed are vectors that can be used in a gene transfer system for stably introducing nucleic acids into the DNA of a cell. The gene transfer systems can be used in methods, for example, gene expression, bioprocessing, gene therapy, insertional mutagenesis, or gene discovery.
Claims15
A method of integrating a transposon into a eukaryotic cell, the method comprising (a) introducing into the cell a transposon comprising SEQ ID NO:
- 7 and SEQ ID NO:
- 8 as left and right ends respectively flanking a heterologous polynucleotide encoding a polypeptide;
- (b) introducing into the cell a transposase, the sequence of which is at least 90% identical to SEQ ID NO:782, wherein the transposase transposes the transposon to produce a genome comprising SEQ ID NO:7 and SEQ ID NO:8 flanking the heterologous polynucleotide at left and right ends respectively;
- and (c) expressing the polypeptide from the heterologous polynucleotide within the genome.
