Small Molecule-Inducible RNA-Targeting Systems for Temporal Control of RNA Regulation in Vivo



RNA regulation is critical for gene expression control, but tools to temporally manipulate RNA regulatory mechanisms are lacking. Here, we present small molecule-inducible RNA-targeting effectors based on our previously developed CRISPR/Cas-inspired RNA targeting system (CIRTS), which can trigger RNA editing, degradation, or translation on target transcripts. We go on to show the inducible CIRTS editor can be deployed for RNA base editing in vivo, providing a new set of tools to probe RNA regulatory dynamics and control gene expression.
