Cyclic nucleotide phosphodiesterase

3'5'-cyclic nucleotide phosphodiesterases are a family of phosphodiesterases. Generally, these enzymes hydrolyze some nucleoside 3',5'-cyclic phosphate to some nucleoside 5'-phosphate thus controlling the cellular levels of the cyclic second messengers and the rates of their degradation.Some examples of nucleoside 3',5'-cyclic phosphate include: 3'5'-cyclic nucleotide phosphodiesterases are a family of phosphodiesterases. Generally, these enzymes hydrolyze some nucleoside 3',5'-cyclic phosphate to some nucleoside 5'-phosphate thus controlling the cellular levels of the cyclic second messengers and the rates of their degradation.Some examples of nucleoside 3',5'-cyclic phosphate include: There are 11 distinct phosphodiesterase families (PDE1–PDE11) with a variety in isoforms and splicing having unique three-dimensional structure, kinetic properties, modes of regulation, intracellular localization, cellular expression, and inhibitor sensitivities.
