Protein attributes

Sequence length	941 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Cyclic nucleotide phosphodiesterase with a dual-specificity for the second messengers cAMP and cGMP, which are key regulators of many important physiological processes.
Catalytic activity	Nucleoside 3',5'-cyclic phosphate + H2O = 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.
Subunit structure	Homodimer By similarity.
Subcellular location	Membrane; Peripheral membrane protein Potential.
Tissue specificity	Expressed in brain and to a lesser extent in heart, placenta, lung, skeletal muscle, kidney and pancreas.
Domain	GAF 1 functions as a dimerization domain, whereas GAF 2 binds cGMP, which causes activation of the catalytic activity of the enzyme By similarity.
Sequence similarities	Belongs to the cyclic nucleotide phosphodiesterase family. PDE2 subfamily. Contains 2 GAF domains.
