How do G-protein-coupled receptors work?

G protein-coupled receptors activates the G proteins. The primary of GPCR function is to transduce extracellular stimuli into intracellular signals. When an external signaling molecule binds to a GPCR, it causes a conformational change in the GPCR. This change then triggers the interaction between the GPCR and a nearby G protein.
