cGMP is second messenger for which hormone (s)
cGMP exist in two forms (Figure 2-29). One form has an extracellular amino-terminal domain that is a receptor, a single transmembrane domain, and a cytoplasmic poion with guanylyl cyclase catalytic activity. Three such guanylyl cyclases have been characterized. Two are receptors for atrial natriuretic peptide (ANP; also known as atrial natriuretic factor), and a third binds an Escherichia coli enterotoxin and the gastrointestinal polypeptide guanylin.(Ref: Ganong's review of medical physiology 23rd Edition page no.57)
