Guanylyl cyclase (also known as guanylate cyclase) is an enzyme that catalyzes the synthesis of cyclic guanosine 3′,5′-monophosphate (cGMP) from guanosine 5' triphosphate (GTP). Guanylyl cyclase exists in both a membrane-bound and soluble form in the cell. The membrane-bound form is a plasma membrane receptor, while soluble forms of guanylyl cyclase undergo activation by nitric oxide ...

Receptors are cellular proteins whose activation causes the cell to modify what it is currently doing. In contrast, an antagonist blocks the action of the agonist, while an inverse agonist causes an action opposite to that of the agonist.
