Abstract excerpt
Prime editing (PE) enables precise nucleotide changes but has limited utility in high-throughput functional screening due to low editing efficiency. Here, we developed EvoPRIME, a PE3-based screening platform that integrates Csy4-mediated processing of Pol II-driven guide RNAs with a fluorescence-based enrichment strategy. EvoPRIME achieves comparable efficiency to state-of-the-art prime editing systems without...
