Summaries for PDE4A Gene

Entrez Gene Summary for PDE4A Gene

  • 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. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.[provided by RefSeq, Jul 2011]

GeneCards Summary for PDE4A Gene

PDE4A (Phosphodiesterase 4A, CAMP-Specific) is a Protein Coding gene. Diseases associated with PDE4A include vasculogenic impotence and jejunoileitis. Among its related pathways are Signaling by GPCR and G Protein Signaling Pathways. GO annotations related to this gene include 3,5-cyclic-nucleotide phosphodiesterase activity and 3,5-cyclic-AMP phosphodiesterase activity. An important paralog of this gene is PDE7A.

UniProtKB/Swiss-Prot for PDE4A Gene

  • Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes.

Tocris Summary for PDE4A Gene

  • Phosphodiesterases (PDEs) are a family of phosphohydrolyases that catalyze the hydrolysis of 3' cyclic phosphate bonds in adenosine and/or guanine 3',5' cyclic monophosphate (cAMP and/or cGMP). PDEs regulate the second messengers by controlling their degradation.
