Abstract:
Bacteria have evolved a variety of effector proteins to facilitate their survival and proliferation within the host environment. Continuous competition at the host-pathogen interface has empowered these effectors with unique mechanism and high specificity toward their host targets. The rich repertoire of bacterial effectors has thus provided us an attractive toolkit for investigating various cellular processes, such as signal transductions. With recent advances in protein chemistry and engineering, we now have the capability for on-demand control of protein activity with high precision. Herein, we review the development of chemically engineered bacterial effectors to control kinase-mediated signal transductions, inhibit protein translation, and direct genetic editing within host cells. We also highlight future opportunities for harnessing diverse prokaryotic effectors as powerful tools for mechanistic investigation and therapeutic intervention of eukaryotic systems.
