Function

The protein encoded by this gene belongs to the cyclic nucleotide phosphodiesterase (PDE) family, and PDE4 subfamily. This PDE hydrolyzes the secondary messenger, cAMP, which is a regulator and mediator of a number of cellular responses to extracellular signals. Thus, by regulating the cellular concentration of cAMP, this protein plays a key role in many important physiological processes.^[6] Recently, it has been shown through the use of PDE4A knock out mice that PDE4A may play a role in the regulation of anxiety and emotional memory.^[7]

Clinical significance

PDE4A inhibition is a target of a number of drugs including:^[8][9][10]

• rolipram (antidepressant and antiinflammatory) and cilomilast (antiinflammatory) – inhibits PDE4A isoforms 1, 2, 6, and 7
• roflumilast (antiinflammatory) – inhibits PDE4A isoforms 1, 2, and 6
• tofisopam (anxiolytic with alleged antiinflammatory properties) – inhibits PDE4A isoform 1, PDE-10A1, PDE-3, and PDE-2A3
