Background: cAMP
Adenosine 3,5-cyclic monophosphate (cAMP) is one of the most important intracellular second messengers. Several hormones are known to activate cAMP and subsequent signaling cascades via their indirect influence on adenylate cyclase, the enzyme responsible for the conversion of ATP to cAMP.
