Background
This gene encodes a cGMP-binding, cGMP-specific phosphodiesterase, a member of the cyclic nucleotide phosphodiesterase family. This phosphodiesterase specifically hydrolyzes cGMP to 5'-GMP. It is involved in the regulation of intracellular concentrations of cyclic nucleotides and is important for smooth muscle relaxation in the cardiovascular system. Alternative splicing of this gene results in three transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008],
Function
catalytic activity:Guanosine 3',5'-cyclic phosphate + H(2)O = guanosine 5'-phosphate.,cofactor:Divalent cations. Zinc ions yields maximum activity. Manganese, magnesium and cobalt also support catalysis but at much higher concentrations.,domain:Composed of a C-terminal catalytic domain containing two putative divalent metal sites and an N-terminal regulatory domain which contains two homologous allosteric cGMP-binding regions, A and B.,enzyme regulation:Sildenafil (Viagra) is a highly selective and potent inhibitor of PDE5A and is effective in the treatment of penile erectile dysfunction. Also inhibited by zaprinast.,function: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.,pathway:Purine metabolism; cGMP degradation; GMP from cGMP: step 1/1.,PTM:Phosphoryla
