It is involved in intra- and inter-cellular signaling in organisms as diverse as bacteria, slime mold, fruit fly and humans.
Cyclic AMP is produced from ATP by the enzyme adenylate cyclase (AC) and is hydrolyzed by cyclic AMP phosphodiesterases. Activation of these enzymes allows for the tight control over the levels of cAMP inside the cell. 详细>
