cGMP-specific 3',5'-cyclic phosphodiesterase (PDE5A)

Plays a role in signal transduction by regulating the intracellular concentration of cyclic nucleotides. This phosphodiesterase catalyzes the specific hydrolysis of cGMP to 5'- GMP (PubMed:9714779, PubMed:15489334).

Specifically regulates nitric-oxide-generated cGMP (PubMed:15489334). .
