WebFeb 26, 2014 · In a manner similar to cAMP and as depicted in Figure 1C, cGMP is formed through the activity of guanylyl cyclase (GC) enzymes from its precursor GTP. One distinct difference from cAMP signaling is that GC enzymes are more evenly dispersed between the membrane and the cytosol of cells and are directly activated by their stimuli [ 3 ]. WebGuanylyl cyclases are usually classified as being either soluble (sGCs) or transmembrane receptors (rGCs), sometimes called transmembrane particulate (pGC) [11, 12]. Soluble GCs are activated by NO only when they are heterodimeric and comprised of an α-and a β-subunit. By contrast, the rGCs function as homodimers [12]. Each rGC polypeptide ...
