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.

DNA vectors, transposons and transposases for eukaryotic genome modification

The invention provides methods for introducing co-varying paired nucleic acids into a vector such under separate transcriptional control. An oligonucleotide is synthesized including the paired nucleic acids. The oligonucleotide is then assembled with a spacer nucleic acid encoding a promoter. After assembly the spacer nucleic acid is to one side of the oligonucleotide encoding the paired segments. However, on circularization of the assembled nucleic acid and cleavage between the DNA segments the spacer oligonucleotide and its components now occur between the paired segments. The resulting nucleic acid can now be cloned into a vector with a single step, such that each of the paired nucleic acid segments is linked to its own promoter. The present method can readily be extended to library screening without proportionately increasing the effort.

Methods for generating libraries with co-varying regions of polynuleotides for genome modification

The present invention provides polynucleotide vectors for high expression of heterologous genes, and methods for constructing such vectors. 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, but not limited to, gene expression, gene therapy, insertional mutagenesis, or gene discovery.
