Voltage-gated Ca channels have been reported to be regulated by membrane potential, phosphorylation and binding of specific agonists or antagonists such as dihydropyridines. We report here evidence that cyclic AMP (cAMP) modulates the activation of Ca-channel current by the dihydropyridine agonist B

Concentration-dependent effects of intracellular GTP on activation of the muscarinic K + channel were examined in inside-out patches of cardiac atrial myocytes. The pipette solution contained 0.i ~I ACh. GTP (0.01-30 ~M) and 0.5 mM MgCI 2 were applied to the inside side of the patch membrane. K + ch
