PDE1A (Phosphodiesterase 1A) is a Protein Coding gene. Among its related pathways are Calcium signaling pathway and DAG and IP3 signaling. Cyclic nucleotide phosphodiesterases (PDEs) play a role in signal transduction by regulating intracellular cyclic nucleotide concentrations through hydrolysis of cAMP and/or cGMP to their respective nucleoside 5-prime monophosphates.
