gRNA for dCas9-VP64 targeting synthetic activation promoter pMLPm

Ribozyme flanked gRNA compatible for dCas9-VP64. gRNA sequence complements 3 different loci in the synthetic promoter pMLPm (2), and gRNA dCas9 complex can promote transcription downstream of syntetic promoter. It has a hammerhead ribozyme on its 5' and an HDV ribozyme on its 3' end. Upon transcription the ribozymes should cleave the mRNA at specific locations to release the mature gRNA (1).

Usage and Biology

guide RNA is a hundred base-long molecule with a unique two dimensional structure which binds Cas9 and guides it to a dsDNA sequence complementary to 21-22 base pairs on the 5' end of the molecule. The gRNA was also assembled into a AAV vector, under the control of human survivin promoter. gRNA scaffold sequence for SaCas9 was used (3). In order to utilize the cancer specific promoter hyperactivation we used an RGR (Ribozyme gRNA Ribozyme). This design allows for gRNAs to be transcribed and processed using RNA polymerase II promoters, since these are the main promoters controlling gene activation (1).
