| Outline of Final Research Achievements |
It is important to analyze in vivo functions of cis-regulatory modules during embryogenesis. However, quick and effective methods for such analysis have never been established. Therefore, I examined whether CRISPRi by a dead Cas9 protein (dCas9) can regulate activities of cis-regulatory modules using Xenopus embryos. Luciferase reporter assays were performed using both dCas9 mRNA and protein. The data showed that CRISPRi could not affect the reporter gene expression. This result suggests that endogenous transcriptional machineries can bump CRISPRi/dCas9 from DNA.
