WebSep 19, 2024 · G-protein coupled receptors are a diverse family of receptors found in a huge range of tissues throughout the body. They function to respond to a wide variety of extracellular signals, such as hormones or neurotransmitters, and trigger intracellular signalling cascades, which regulate a wide range of bodily functions. WebHow are G protein coupled receptors activated? Upon activation by a ligand, the receptor binds to a partner heterotrimeric G protein and promotes exchange of GTP for GDP, leading to dissociation of the G protein into α and bγ subunits that mediate downstream signals.
