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.

Name Definition
cAMP metabolic process The chemical reactions and pathways involving the nucleotide cAMP (cyclic AMP, adenosine 3',5'-cyclophosphate).
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.
cGMP metabolic process The chemical reactions and pathways involving cyclic GMP, guanosine 3',5'-phosphate.
