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.
