Phosphodiesterase 3A - PDE3A

Target Class Non-Kinase Enzymes FamilyPhosphodiesterase
This gene encodes a member of the cGMP-inhibited cyclic nucleotide phosphodiesterase (cGI-PDE) family. cGI-PDE enzymes hydrolyze both cAMP and cGMP, and play critical roles in many cellular processes by regulating the amplitude and duration of intracellular cyclic nucleotide signals. The encoded protein mediates platelet aggregation and also plays important roles in cardiovascular function by regulating vascular smooth muscle contraction and relaxation. Inhibitors of the encoded protein may be effective in treating congestive heart failure. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

Enzyme and test compound are preincubated for 15 minutes at room temp before substrate addition. cAMP substrate (at a concentration equal to EC80) is added and incubated at room temperature for 30 minutes. Enzyme reaction is terminated by addition of 9 mM IBMX. Signal is detected using the HitHunter® cAMP detection kit.
