Engineered nucleases are capable of efficiently modifying complex genomes through introduction of targeted double-strand breaks. However, mammalian genome engineering remains limited by low efficiency of heterologous DNA integration at target sites, which is typically performed through homologous recombination, a complex, ineffective and costly process. In this study, we developed a multiplexable and universal nuclease-assisted vector integration system for rapid generation of gene knock outs using selection that does not require customized targeting vectors, thereby minimizing the cost and time frame needed for gene editing. Importantly, this system is capable of remodeling native mammalian genomes through integration of DNA, up to 50 kb, enabling rapid generation and screening of multigene knockouts from a single transfection. These results support that nuclease assisted vector integration is a robust tool for genome-scale gene editing that will facilitate diverse applications in synthetic biology and gene therapy.
