== Function ==
[https://www.uniprot.org/uniprot/PDE5A_HUMAN PDE5A_HUMAN] 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.[https://www.uniprot.org/uniprot/PDE4B_HUMAN PDE4B_HUMAN] Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes. May be involved in mediating central nervous system effects of therapeutic agents ranging from antidepressants to antiasthmatic and anti-inflammatory agents.<ref>PMID:10846163</ref> <ref>PMID:15003452</ref>
