Defining E3 ligase–substrate relationships through multiplex CRISPR screening

Abstract excerpt

Abstract Specificity within the ubiquitin–proteasome system is primarily achieved through E3 ubiquitin ligases, but for many E3s their substrates—and in particular the molecular features (degrons) that they recognize—remain largely unknown. Current approaches for assigning E3s to their cognate substrates are tedious and low throughput. Here we developed a multiplex CRISPR screening platform to assign E3 ligases...
