ADRB2 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.
GsaL is the long splice variant of the alpha-subunit of the heterotrimeric G-protein Gs. Gs activates the effector adenylate cyclase. GsaL differs from the short splice variant by a 15 amino acid insert between the ras-like domain and the alpha-helical domain.
