High affinity cAMP-specific and IBMX-insensitive 3',5'-cyclic phosphodiesterase 8A (PDE8A)

Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes (PubMed:18983167). May be involved in maintaining basal levels of the cyclic nucleotide and/or at the cAMP regulation of germ cell development (PubMed:18983167).

Binding to RAF1 reduces RAF1'Ser- 259' inhibitory-phosphorylation and stimulates RAF1-dependent EGF- activated ERK-signaling (PubMed:23509299). Protects against cell death induced by hydrogen peroxide and staurosporine (PubMed:23509299).
