    摘要: This invention pertains to mutant Cas9 nucleic acids and proteins for use in CRISPR/Cas endonuclease systems, and their methods of use. In particular, the invention pertains to an isolated mutant Cas9 protein, wherein the isolated mutant Cas9 protein is active in a CRISPR/Cas endonuclease system, wherein the CRISPR/Cas endonuclease system displays reduced off-target editing activity and maintained on-target editing activity relative to a wild-type CRISPR/Cas endonuclease system. The invention also includes isolated nucleic acids encoding mutant Cas9 proteins, ribonucleoprotein complexes and CRSPR/Cas endonuclease systems having mutant Cas9 proteins that display reduced off-target editing activity and maintained on-target editing activity relative to a wild-type CRISPR/Cas endonuclease system.
