ABSTRACT
Directly modulating the activity of genome-editing proteins has the potential to increase their specificity by reducing activity following target locus modification. We developed Cas9 nucleases that are activated by the presence of a cell-permeable small molecule by inserting an evolved 4-hydroxytamoxifen-responsive intein at specific positions in Cas9. In human cells, conditionally active Cas9s modify target genomic sites with up to 25-fold higher specificity than wild-type Cas9.
