Theophylline-induced synergic activation of guide RNA to control CRISPR/Cas9 function

Abstract

Ligand-induced activation of CRISPR/Cas9 function is achieved based on a synergic approach through the integration of the theophylline aptamer into protein-unrecognized regions of guide RNA. This design of allosteric regulation opens a new window towards the broad involvement of RNA aptamers for conditional control of CRISPR/Cas9 function.
