G(i) Proteins Regulate Adenylyl Cyclase Activity Independent of Receptor Activation

BACKGROUND AND PURPOSE: Despite the view that only β(2)- as opposed to β(1)-adrenoceptors (βARs) couple to G(i), some data indicate that the β(1)AR-evoked inotropic response is also influenced by the inhibition of G(i). Therefore, we wanted to determine if G(i) exerts tonic receptor-independent inhi...
