- Cyclic nucleotide signaling and cAMP phosphodiesterases
Cyclic adenosine monophosphate (cAMP) is a ubiquitous second messenger that regulates a myriad of physiological processes. Its cellular concentration is determined by the rate of its synthesis by adenylyl cyclases and the rate of its degradation by cyclic nucleotide phosphodiesterases (PDEs). The mammalian PDEs encompass a large number of isoenzymes grouped into eleven families. Our laboratory explores the structure, regulation and physiological functions of Type 4 PDEs (PDE4s), the largest and most widely expressed PDE family.
