RGS (Regulators of G protein signaling) are protein structural domains that activate GTPases for heterotrimeric G-protein alpha-subunits.GTPase-accelerating RGS proteins have multiple functions, including promoting GTP hydrolysis by heterotrimeric G protein alpha subunits, which inactivates the G protein and quickly cuts off G protein-coupled receptor signaling pathways. Heterotrimeric G proteins exchange GDP for GTP when GPCRs activate them. They are then freed from the receptor and split into an active, free GTP-bound alpha subunit and a beta-gamma dimer, which both trigger downstream effectors.The alpha subunit's hydrolysis of GTP ends the response, allowing it to bind both the receptor and the beta-gamma dimer. RGS proteins stabilize the G protein transition state, thereby significantly reducing the lifetime of GTP-bound alpha subunits. A component of every RGS protein called the RGS-box, or RGS domain, is necessary for its function. RGS1 and RGS4, two tiny RGS proteins, are essentially just RGS domains, but others have extra domains that add extra functionality.
