WebThe protein encoded by this gene belongs to the cyclic nucleotide phosphodiesterase (PDE) family, and PDE4 subfamily. This PDE hydrolyzes the secondary messenger, cAMP, which is a regulator and mediator of a number of cellular responses to extracellular signals. WebCyclic-AMP is broken down by an enzyme called cAMP-dependent phosphodiesterase (PDE). The isoform of this enzyme that is targeted by currently used clinical drugs is the type 3 form (PDE3). Inhibition of this enzyme prevents cAMP breakdown and thereby increases its intracellular concentration .

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.
