FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene belongs to the cyclic nucleotide phosphodiesterase (PDE) family, and PDE8 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 found for this gene.[provided by RefSeq, Jul 2011]
PHENOTYPE: Targeted disruption of this gene results in a 4-fold increase in basal release of testosterone in isolated Leydig cells as well as a significant increase in the sensitivity to luteinizing hormone, measured as testosterone released into the media. [provided by MGI curators]
