PDE1B Proteins and Enzymes

PDE1B, a variant of PDE1, is a Ca2+-calmodulin-stimulated phosphodieterase (PDE) preferentially hydrolyzing cGMP. Cyclic nucleotides are hydrolyzed and compartmentalized by a family of enzymes called phosphodieterases. In mammals at least 11 different families of PDEs can be discriminated (PDE1-11) based on their kinetic properties and inhibition to various pharmacological agents. Three different PDE1 genes have been identified (PDE1A, PDE1B, PDE1C). The enzymes of the PDE1A and PDE1B have ...
