"FUNCTION: Cyclic nucleotide phosphodiesterase with a dual- specificity for the second messengers cAMP and cGMP, which are key regulators of many important physiological processes. Involved in oocyte maturation. CATALYTIC ACTIVITY: Nucleoside 3',5'-cyclic phosphate + H(2)O = nucleoside 5'-phosphate. COFACTOR: Binds 2 divalent metal cations per subunit. Site 1 may preferentially bind zinc ions, while site 2 has a preference for magnesium and/or manganese ions (By similarity). ENZYME REGULATION: Inhibited by cGMP (By similarity). BIOPHYSICOCHEMICAL PROPERTIES: Kinetic parameters: KM=0.2 uM for cAMP; SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein (Potential). SIMILARITY: Belongs to the cyclic nucleotide phosphodiesterase family. PDE3 subfamily. GENE SYNONYMS:Pde3a.
