The clustered, regularly interspaced short palindromic repeats‐associated protein 9 endonuclease (CRISPR‐Cas9) and the nuclease‐deactivated Cas9 (dCas9) systems have revolutionized our ability to precisely engineer and regulate genomes. Inducible CRISPR‐dCas9‐based transcriptional systems have been rapidly developed to conditionally control genetic manipulation. Current strategies mainly focus on conditional control of gRNA function and dCas9 protein using exogenous and endogenous triggers, including external light, small molecules, synthetic and intracellular oligonucleotides. These strategies have established novel platforms for the spatiotemporal regulation of genome activation and repression, epigenome editing, and so on. Herein, we summarize the recent progress in conditionally controlling CRISPR‐dCas9 transcriptional systems through gRNA modulation and dCas9 protein engineering.
