G-protein-coupled receptors (GPCRS) all have a similar structure with seven transmembrane
domains. When a GPCR binds an extracellular signal, an intracellular G protein, composed
of BLANK subunits, becomes activated. BLANK of the G-protein subunits are tethered to
the plasma membrane by short lipid tails. When unstimulated, the a subunit contains
BLANK, which is exchanged for BLANK on stimulation. The intrinsic BLANK activity of
the a subunit is important for inactivating the G protein. BLANK inhibits this activity of the
a subunit, thereby keeping the subunit in an active state.
