Open AccessA Type II-B Cas9 nuclease with minimized off-targets and reduced chromosomal translocations in vivo
Streptococcus pyogenes Cas9 (SpCas9) and derived enzymes are widely used as genome editors, but their promiscuous nuclease activity often induces undesired mutations and chromosomal rearrangements. Several strate...

Bridge helix arginines play a critical role in Cas9 sensitivity to mismatches
The RNA-programmable DNA-endonuclease Cas9 is widely used for genome engineering, where a high degree of specificity is required. To investigate which features of Cas9 determine the sensitivity to mismatches a...

Open AccessCRISPR-Switch regulates sgRNA activity by Cre recombination for sequential editing of two loci
CRISPR-Cas9 is an efficient and versatile tool for genome engineering in many species. However, inducible CRISPR-Cas9 editing systems that regulate Cas9 activity or sgRNA expression often suffer from significa...

CRISPR RNA maturation by trans-encoded small RNA and host factor RNase III
CRISPR/Cas systems constitute a widespread class of immunity systems that protect bacteria and archaea against phages and plasmids, and commonly use repeat/spacer-derived short crRNAs to silence foreign nuclei...
