WebThe specific second messenger pathway that is activated or suppressed by G-protein action depends on the type of alpha subunit. For example, norepinephrine can act on either alpha- or beta-adrenergic receptors. Beta-adrenergic GPCRs couple to a stimulatory G-protein, or G s, which initiates the cyclic AMP (cAMP) second messenger system by ... WebWhat are examples of secondary messengers? Examples of second messenger molecules include cyclic AMP, cyclic GMP, inositol triphosphate, diacylglycerol, and calcium.
