    ADBR2 is a member of the G protein-coupled receptor superfamily. It is activated by the catecholamine epinephrine and couples to the G protein Gs to mediate adenylate cyclase activation. The beta-2-adrenergic receptor binds epinephrine with an approximately 30-fold greater affinity than it does norepinephrine. The G protein family of signal transducers includes 5 heterotrimers, which are most clearly distinguished by their different alpha chains; they have virtually identical beta chains and similar gamma chains. G protein alpha inhibitor chain 2 is a subunit of the G(i) G protein, whose role is in inhibiting adenylate cyclase activity in response to bound GTP. The G proteins possess GTPase activity and are components of a complex membrane signaling system that includes membrane bound receptors. The system exists to modulate extracellular signals as they are transmitted into the cell. GNB1 is a beta subunit. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction.
