http://www.signalingpathways.org/index.jsf WebThe PKA activation pathway is an example of a signal transduction cascade, in which tying several signaling events together amplifies the original signal inside the cell. For each activated GPCR molecule, many G-proteins can be activated, and each active G-protein can synthesize many cAMP molecules, continuing the cascade to PKA and further downstream.
