Systematic interrogation of gene function requires the ability to perturb gene expression in a robust and generalizable manner. We describe structure-guided engineering of a CRISPR-Cas9 complex to mediate efficient transcriptional activation at endogenous genomic loci. We use these engineered Cas9 activation complexes to investigate sgRNA targeting rules for effective transcriptional activation, demonstrate multiplexed activation of 10 genes simultaneously, and upregulate long intergenic non-coding RNA (lincRNA) transcripts. We also synthesize a library consisting of 70,290 guides targeting all human RefSeq coding isoforms to screen for genes which, upon activation, confer resistance to a BRAF inhibitor. Expected and potentially novel resistance genes are enriched in the top hits and are validated using individual sgRNA as well as cDNA overexpression. The signature of our top screening hits is significantly correlated with gene expression data from clinical melanoma samples. These results collectively demonstrate the potential of Cas9-based activators as a powerful genetic perturbation technology.
