G proteins are molecular switches that are activated by receptor-catalyzed GTP for GDP exchange on the G protein alpha subunit, which is the rate-limiting step in the activation of all downstream signaling.eterotrimeric G proteins couple the activation of heptahelical receptors at the cell surface to the intracellular signaling cascades that mediate the physiological responses to extracellular stimuli.
Receptors that activate transmembrane ion channels. These channels are called 'ligand-gated ion channels'. Receptors that use as their transducer the 'G-protein'. Often these receptors can couple promiscuously with several different G-proteins, who are in turn not particularly faithful to a single receptor.
