Abstract: The present invention concerns a method for modulating double-strand break-induced homologous recombination through the identification of effectors that modulate said double-strand break-induced homologous recombination by uses of interfering agents; these agents are capable of modulating double-strand break-induced homologous recombination through their respective actions on said effectors. The present invention also concerns the uses of these effectors and interfering agents and derivatives, respectively, by introducing them in an eukaryotic cell in order to modulate and more particularly to increase double-strand break-induced homologous recombination and gene targeting efficiency. The present invention also relates to specific derivatives of identified effectors and interfering agents, vectors encoding them, compositions and kits comprising such derivatives in order to modulate and more particularly to increase double-strand break-induced homologous recombination and gene targeting efficiency.
