How do receptors activate G proteins? - PubMed

G proteins and their receptors (GPCRs) form one of the most prevalent signalling systems in mammalian cells, regulating systems as diverse as sensory perception, cell growth and hormonal regulation. At the cell surface, the binding of ligands such as hormones and neurotransmitters to a GPCR activates the receptor by causing a conformational change, which in turn activates the bound G protein on the intracellular-side of the membrane. The activated receptor promotes the exchan… Webb. G-alpha dissociates from the G-beta/gamma subunits. c. G-alpha releases GDP and binds GTP. d.
