ligand-activated and ligand-deactivated sgRNAs
RNA ElementLigand-activated and ligand-deactivated sgRNAs are engineered single-guide RNAs that place CRISPR-Cas9-based gene repression under small-molecule control. In the reported 2019 Nature Communications study, sgRNA function was activated or deactivated in a dose-dependent manner by two different ligands, with regulation acting directly at the level of each target-specific sgRNA.
