Descriptions

PDE5A plays a role in signal transduction by regulating the intracellular concentration of cyclic nucleotides. PDE5A contains a catalytic domain that hydrolyzes cGMP and a regulatory (R) domain (1-539) that contains two GAFs, a and b. The R domain binds cGMP allosterically, provides for dimerization, and is phosphorylated at a site regulated by allosteric cGMP binding. The sequence containing GAF b and its flanking amino acids (403-539) autoinhibits the cGMP-binding affinity of GAF a.

4 GO annotations of biological process

Name Definition
cAMP-mediated signaling Any intracellular signal transduction in which the signal is passed on within the cell via cyclic AMP (cAMP). Includes production of cAMP, and downstream effectors that further transmit the signal within the cell.
metabolic process The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
negative regulation of cAMP-mediated signaling Any process which stops, prevents, or reduces the frequency, rate or extent of cAMP-mediated signaling.
negative regulation of cGMP-mediated signaling Any process that decreases the rate, frequency or extent of cGMP-mediated signaling.
