Proteomics and Beyond: Cell Decision-Making Shaped by Reactive Electrophiles

Revolutionary proteomic strategies have enabled rapid profiling of the cellular targets of electrophilic small molecules. However, precise means to directly interrogate how these individual electrophilic modifications at low occupancy functionally reshape signaling networks have until recently been largely limited. We highlight here new methods that transcend proteomic platforms to forge a quantitative link between protein target-selective engagement and downstream signaling. We focus on recent progress in the study of non-enzyme-assisted signaling mechanisms and crosstalk choreographed by native reactive electrophilic species (RES). Using this as a model, we offer a long-term vision of how these toolsets together with fundamental biochemical knowledge of precision electrophile signaling may be harnessed to assist covalent ligand-target matching and ultimately amend disease-specific signaling dysfunction.
