Gene Name PDE5A
Uniprot ID PDE5A_HUMAN
KEGG Pathway hsa:8654
Protein Family Cyclic nucleotide phosphodiesterase family
Protein 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 (PubMed:9714779, PubMed:15489334). Specifically regulates nitric-oxide-generated cGMP (PubMed:15489334).
