Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes . May be involved in maintaining basal levels of the cyclic nucleotide and/or in the cAMP regulation of germ cell development .

Protects against cell death induced by hydrogen peroxide and staurosporine .
