WebThe second messenger cGMP has three major effector systems within the cell: cGMP-regulated ion channels, cGMP-regulated phosphodiesterases and PKGs. PKG I mediates cGMP-induced smooth muscle cell relaxation and inhibition of platelet aggregation. These effects correlate at least partly with an inhibition of calcium release from intracellular ... WebCyclic guanosine monophosphate ( cGMP) is a cyclic nucleotide derived from guanosine triphosphate (GTP). cGMP acts as a second messenger much like cyclic AMP. Its most likely mechanism of action is activation of intracellular protein kinases in response to the binding of membrane -impermeable peptide hormones to the external cell surface.

WebDec 18, 2024 · cGMP signaling is conveyed by several effectors including PKG, cGMP-gated ion channels and phosphodiesterases. A major cGMP effector is PKG-I, which plays a key role in the regulation of smooth vascular and cardiac function (Hofmann 2024 ). PKG-I is a homodimeric enzyme that is expressed as two isoforms, PKG-Iα and Iβ. WebThe elevated intracellular cGMP level exerts its physiological action through two forms of cGMP-dependent protein kinase (PKG), cGMP-regulated phosphodiesterases (PDE2, PDE3) and cGMP-gated cation channels, among which PKGs might be the primary mediator.
