Abstract

This disclosure provides an engineered system comprising: a first nucleic acid molecule encoding a CasX nuclease, and a guide RNA (gRNA) or a second nucleic acid molecule encoding the gRNA, where the first nucleic acid molecule is codon optimized for a eukaryotic cell, and where the gRNA is designed to hybridize with a target site in the eukaryotic cell. Further, this disclosure provides a method of modifying at least one target site in a eukaryotic genome comprising: providing a eukaryotic cell with a CasX nuclease or a first nucleic acid molecule encoding the CasX nuclease, and providing the eukaryotic cell with a guide RNA (gRNA) or a second nucleic acid molecule encoding the gRNA, where the gRNA and the CasX nuclease form a complex, where the gRNA hybridizes to the target site, and where the complex generates a modification at the target site.
