NOVEL HIGH FIDELITY RNA-PROGRAMMABLE ENDONUCLEASE SYSTEMS AND USES THEREOF

Abstract:

Described herein are novel systems for targeting, editing or manipulating DNA in a cell, using novel M-SmallCas9 nucleases and variants thereof. The M-SmallCas9 nucleases are derived from wildtype or parental small type II CRISPR Cas9 endonucleases, and display improved fidelity compared to parental type II CRISPR Cas9 enzymes in combination with a simple PAM sequences and are small endonuclease size.
