WebMay 27, 2024 · CRISPRi and CRISPRa utilize catalytically inactive Cas9 and transcriptional activators and repressors to modulate gene expression (dCas9 KRAB and dCas9 VP64, respectively). In the endogenous context, multiple transcription factors and cofactors work in synchrony to stimulate gene transcription. WebA catalytically inactive Cas9 (dCas9) is fused to FokI nuclease. When FokI dimerizes, it generates a double-strand break (DSB) at a specific sequence. Two unique gRNAs, …
WebThe catalytic domains of Cas9 are mutated to generate the inactive dCas9 (nuclease – dead mutants of Cas9) lacking the endonuclease activity but instead, it still can be in conjunction with the sgRNA (Jinek et al., 2012). Consequently, the dCas9-sgRNA complex specifically binds to the target gene at the promoter or coding sequence and acts as ...
