Official Full Name PDE4B phosphodiesterase 4B, cAMP-specific
Background Cyclic nucleotide phosphodiesterases (PDEs) catalyse the hydrolytic inactivation of the common intracellular second messengers cyclic adenosine and guanosine 3, 5monophosphate (cAMP and cGMP). Thus, these enzymes play a critical role in the regulation of a wide range of physiological processes modulated by cyclic nucleotide signalling.The PDE4 enzyme belongs to a family of cAMPdependent PDEs that provide the major means of inactivating the key intracellular second messenger, cAMP. Four genes (4A, 4B, 4C, and 4D) encode around 20 distinct isoform members of the PDE4 family. Each isoform is characterized by a unique Nterminal region
