  • Patent number: 11905623
    Abstract: Some aspects of the present disclosure provide methods for evolving recombinases to recognize target sequences that differ from the canonical recognition sequences. Some aspects of this disclosure provide evolved recombinases, e.g., recombinases that bind and recombine naturally-occurring target sequences, such as, e.g., target sequences within the human Rosa26 locus. Methods for using such recombinases for genetically engineering nucleic acid molecules in vitro and in vivo are also provided. Some aspects of this disclosure also provide libraries and screening methods for assessing the target site preferences of recombinases, as well as methods for selecting recombinases that bind and recombine a non-canonical target sequence with high specificity.
