PDE3A is a member of the phosphodiesterase family of proteins that play a critical role in regulating intracellular levels of cAMP and cGMP. PDE3A has high affinity for both cAMP and cGMP and shows competitive inhibition of the cAMP hydrolytic activity by cGMP (1). Deletion of the N-terminus of PDE3A enhances the hydrolysis of cGMP relative to cAMP suggesting that the role of divergent N-termini of various PDEs could be to exert substrate specificity. Stimulation of platelets with thrombin increases PDE3A activity via Akt signaling pathway and this increase can be diminished by dephosphorylation of PDE3A by protein phosphatase 1 (2).
