PDE2A (Phosphodiesterase 2A): PDE2A is an enzyme that regulates cyclic nucleotide signaling by hydrolyzing cyclic AMP (cAMP) and cyclic GMP (cGMP). It plays a role in cellular signal transduction and is involved in processes such as smooth muscle contraction and cardiac function. PDE2A inhibitors are being explored for their potential in treating heart diseases and other conditions....
