The intracellular signal transduction pathway that utilizes cyclic AMP as a key messenger was the first such pathway to be described and has served as a model for many other transducing systems. Now Iyengar illustrates how this classic pathway has yet another function—in a number of different biological systems, the cyclic AMP pathway appears to gate (either negatively or positively) other signal transduction pathways.
