Description

G protein-coupled receptors (GPCRs) represent the largest family of cell surface proteins. Agonist binding to GPCRs activates G proteins regulating many cellular effectors. Classically, G protein activation occurs at the plasma membrane and is rapidly terminated by β-arrestin recruitment to the activated GPCRs, promoting G protein uncoupling from receptor, GPCR internalisation and signalling arrest. However, recent studies revealed that upon internalisation, some GPCRs continue to activate G proteins from internal compartments leading to sustained production of second messengers far from the plasma membrane. This different spatiotemporal signalling profile allow...
