Abstract
The present disclosure provides variant Cas9 proteins, nucleic acids encoding the variant Cas9 proteins, and host cells comprising the nucleic acids. The present disclosure provides systems that include a subject variant Cas9 protein (and/or a nucleic acid encoding the variant Cas9 protein) and a Cas9 guide RNA. In some cases, a subject system includes a PAMmer and/or a donor polynucleotide. The variant Cas9 proteins and the nucleic acids encoding the variant Cas9 proteins are useful in a wide variety of methods, which are also provided. In some embodiments, a variant Cas9 protein includes a RuvC domain, an HNH domain, and a disrupted RuvC/HNH linker region that reduces the RuvC cleavage activity of the protein. In some embodiments, a variant Cas9 protein includes a deletion (of all or a part of the HNH domain) or an insertion (within the HNH domain) that reduces the HNH cleavage activity of the protein.
