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 . Binding to RAF1 reduces RAF1 'Ser-259' inhibitory-phosphorylation and stimulates RAF1-dependent EGF-activated ERK-signaling . Protects against cell death induced by hydrogen peroxide and staurosporine .
Expressed in most tissues except thymus and peripheral blood leukocytes. Highest levels in testis, ovary, small intestine and colon.
