The noncoding genome affects gene regulation and disease, yet we lack tools for rapid identification and manipulation of noncoding elements. We develop a CRISPR screen employing ~18,000 sgRNAs targeting >700 kb surrounding the genes NF1, NF2, and CUL3, which are involved in BRAF inhibitor resistance in melanoma. We find that noncoding locations that modulate drug resistance also harbor predictive hallmarks of noncoding function. With a subset of regions at the CUL3 locus, we demonstrate that engineered mutations alter transcription factor occupancy and long-range and local epigenetic environments, implicating these sites in gene regulation and chemotherapeutic resistance. Though our expansion of the potential of pooled CRISPR screens we provide tools for genomic discovery and for elucidating biologically relevant mechanisms of gene regulation. Pooled CRISPR mutagenesis identifies functional elements in the noncoding genome.
