High affinity cGMP-specific 3',5'-cyclic phosphodiesterase 9A

Gene

Pde9a

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Specifically hydrolyzes the second messenger cGMP, which is a key regulator of many important physiological processes (PubMed:9624145). Highly specific: compared to other members of the cyclic nucleotide phosphodiesterase family, has the highest affinity and selectivity for cGMP. Specifically regulates natriuretic-peptide-dependent cGMP signaling in heart, acting as a regulator of cardiac hypertrophy in myocytes and muscle. Does not regulate nitric oxide-dependent cGMP in heart (PubMed:25799991). Additional experiments are required to confirm whether its ability to hydrolyze natriuretic-peptide-dependent cGMP is specific to heart or is a general feature of the protein (Probable). In brain, involved in cognitive function, such as learning and long-term memory (PubMed:22328573, PubMed:24746365).Curated4 Publications

Catalytic activityi

Guanosine 3',5'-cyclic phosphate + H2O = guanosine 5'-phosphate.1 Publication

Cofactori

Protein has several cofactor binding sites:
  • Zn2+By similarityNote: Binds 1 Zn2+ ion per subunit. Binds 2 divalent metal cations per subunit: site 1 preferentially binds zinc, while site 2 has a preference for magnesium. Tightly binds zinc.By similarity
  • Mg2+By similarityNote: Binds 1 Mg2+ ions per subunit. Binds 2 divalent metal cations per subunit: site 1 preferentially binds zinc, while site 2 has a preference for magnesium. Binds magnesium less tightly than zinc.By similarity

Enzyme regulationi

Inhibited by SCH 51866 and moderately, by zaprinast. Specifically inhibited by PF-04447943 (6-[(3S,4S)-4-methyl-1-(pyrimidin-2-ylmethyl)pyrrolidin-3-yl]-1-(tetrahydro-2H-pyran-4-yl)-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one) (PubMed:22328573).2 Publications

    Pathwayi: 3',5'-cyclic GMP degradation

    This protein is involved in step 1 of the subpathway that synthesizes GMP from 3',5'-cyclic GMP.
    Proteins known to be involved in this subpathway in this organism are:
    1. cGMP-specific 3',5'-cyclic phosphodiesterase (Pde5a), High affinity cGMP-specific 3',5'-cyclic phosphodiesterase 9A (Pde9a), cAMP and cAMP-inhibited cGMP 3',5'-cyclic phosphodiesterase 10A (Pde10a)
    This subpathway is part of the pathway 3',5'-cyclic GMP degradation, which is itself part of Purine metabolism.
