ABSTRACT
G-protein-coupled receptors (GPCRs) integrate extracellular cues into intracellular signals to modulate the cellular state. Owing to their diverse modulatory functions, GPCRs represent one of the major drug targets of the pharmaceutical industry. Until now, the characterization and control of GPCRs and their intracellular signalling cascades have mainly relied on chemical compounds, which either activate or inhibit GPCR pathways, albeit with limited receptor and cell-type specificity. Recently, new approaches have been developed to control signalling cascades in cell- and receptor-type-specific ways. The chemical approach focuses on GPCR design and activation by an inert chemical compound, whereas the physical approach uses designer GPCRs and activation by physical stimuli, such as light.
