Combining with epinephrine or norepinephrine to initiate a change in cell activity. Combining with epinephrine or norepinephrine to initiate a change in cell activity via activation of a G protein, with pharmacological characteristics of alpha-adrenergic receptors. A receptor that binds an extracellular ligand and transmits the signal to a heterotrimeric G-protein complex. These receptors are characteristically seven-transmembrane receptors and are made up of hetero- or homodimers. Combining with epinephrine or norepinephrine to initiate a change in cell activity via activation of a G protein, with pharmacological characteristics of beta-adrenergic receptors; the activity involves transmitting the signal to the Gs alpha subunit of a heterotrimeric G protein. A receptor that binds an extracellular amine and transmits the signal to a heterotrimeric G-protein complex. These receptors are characteristically seven-transmembrane receptors and are made up of hetero- or homodimers.
