cAMP-specific 3',5'-cyclic phosphodiesterase 4A is an enzyme that in humans is encoded by the PDE4A gene.^[1][2]

Function

The protein encoded by this gene belongs to the cyclic nucleotide phosphodiesterase (PDE) family, and PDE4 subfamily. This PDE hydrolyzes the second 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.^[2] 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.^[3]

Clinical significance

PDE4A is a target of a number of drugs including:<ref name=pmid"11306681">Rena G, Begg F, Ross A, MacKenzie C, McPhee I, Campbell L, Huston E, Sullivan M, Houslay MD (May 2001).

• rolipram (antidepressant and antiinflammatory) and cilomilast (antiinflammatory) – inhibits PDE4A isoforms 1, 2, 6, and 7
• roflumilast (antiinflammatory) – inhibits PDE4A isoforms 1, 2, and 6
