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.

The invention provides methods for genetically engineering T cells in vivo comprising administering to the subject a cytokine or nucleic acid molecule encoding a cytokine to recruit the subject's T cells to the administration site; followed by administration of a nucleic acid molecule encoding an antigen receptor. In some instances, the method also includes administering an integrase or nucleic acid molecule encoding an integrase to integrate the sequence encoding the antigen receptor into the DNA of the recruited T cells.
