Biological function summary
Phosphodiesterase 3A plays an important role in cardiac and vascular functions. It forms part of a signaling complex responsible for regulating cardiovascular responses. PDE3A manages intracellular cAMP and cGMP concentrations impacting vascular smooth muscle relaxation and platelet aggregation. The modulation of these signaling molecules by PDE3A contributes to maintaining normal heart rhythms and influencing blood pressure.
Pathways
Phosphodiesterase 3A is central to the cAMP and cGMP signaling pathways. PDE3A activity connects to the cardiac contractility pathway where it works alongside proteins like protein kinase A (PKA) which depends on cAMP levels. In the vascular system PDE3A activity is interlinked with the nitric oxide (NO) pathway where it modulates the effects of cGMP-dependent protein kinase (PKG). Together they orchestrate vascular actions such as smooth muscle contraction and vasodilation.

General info
Function
Cyclic nucleotide phosphodiesterase with specificity for the second messengers cAMP and cGMP, which are key regulators of many important physiological processes (PubMed : 1315035, PubMed : 25961942, PubMed : 8155697, PubMed : 8695850). Has also activity toward cUMP (PubMed : 27975297). Independently of its catalytic activity it is part of an E2/17beta-estradiol-induced pro-apoptotic signaling pathway. E2 stabilizes the PDE3A/SLFN12 complex in the cytosol, promoting the dephosphorylation of SLFN12 and activating its pro-apoptotic ribosomal RNA/rRNA ribonuclease activity. This apoptotic pathway might be relevant in tissues with high concentration of E2 and be for instance involved in placenta remodeling (PubMed : 31420216, PubMed : 34707099).
Sequence similarities
Belongs to the cyclic nucleotide phosphodiesterase family. PDE3 subfamily.
