WebCyclic nucleotide levels are largely regulated through catabolic processes directed by phosphodiesterases (PDEs). The PDE superfamily is large and complex, with over 60 distinct isoforms that preferentially hydrolyze cAMP, cGMP, or both. PDEs contribute to compartmentalized cyclic nucleotide signaling. WebAbstract By catalyzing hydrolysis of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP), cyclic nucleotide phosphodiesterases are critical regulators of their intracellular concentrations and their biological effects.
