methylation-deactivated and demethylase-activated CRISPR-Cas12a guide RNA strategy
RNA ElementThe methylation-deactivated and demethylase-activated CRISPR-Cas12a guide RNA strategy is an RNA-level control system in which m6A or m1A modification of the Cas12a guide RNA suppresses CRISPR-Cas12a activity, while demethylation restores function. It was reported as a way to regulate Cas12a for controllable gene editing, gene expression regulation, and demethylase imaging in living cells.
