dCas9-ω

An RNA polymerase ω subunit is fused to the C-terminal of dCas9.

Usage and Biology

The dCas9 is a Cas9 nuclease mutant. Mutations D10A and H840A in the RucC and HNH domains, respectively, abolish cleavage but do not impair DNA binding. The dCas9 provides a simple and robust technology for gene repression and activation, and can target almost any DNA sequence aided by the sgRNA. The ω subunit can activate transcription by recruiting the RNAP holoenzyme. The fusion between dCas9 and ω subunit can activate gene transcription downstream of the protospacer. The CRISPR interference inhibits transcription by sterically blocking the RNA polymerase(RNAP).
