The RNA-guided nuclease Cas9 can be reengineered as a programmable transcription
factor. However, modest levels of gene activation have limited potential
applications. We describe an improved transcriptional regulator obtained through
the rational design of a tripartite activator, VP64-p65-Rta (VPR), fused to
nuclease-null Cas9. We demonstrate its utility in activating endogenous coding
and noncoding genes, targeting several genes simultaneously and stimulating
neuronal differentiation of human induced pluripotent stem cells (iPSCs).
