Function

3′,5′-cyclic nucleotide phosphodiesterases (PDEs) are enzymes that hydrolyse 3',5'-phosphodiester bonds in two of the most important cell signalling molecules, cyclic-adenosine monophosphates (cAMPs) and cyclic-guanosine monophosphates (cGMPs). PDEs are essential for the inactivation of cAMP and or cGMP to regulate their intracellular concentrations and maintain cellular homeostasis ^[1]. PDEs directly modulate these messenger molecules by degrading cAMP or cGMP when concentrations are elevated beyond the cellular threshold ^[2].
