Signaling via guanylyl cyclase C: cGMP, Src and p21
Background Guanylyl cyclase C (GC-C) is a receptor expressed in intestinal epithelial cells and activation of GCC by its ligands elevates intracellular cGMP which results in an inhibition of cell proliferation [1]. Multiple regulatory mechanisms operate in GC-C to modulate its activity, and include ligand binding to the extracellular domain, ATP binding to the kinase homology domain and additio...
متن کاملNO signalling in mice lacking the NO receptor guanylyl cyclase
NO-sensitive guanylyl cyclase (NO-GC) is accepted to be the major receptor for the signaling molecule NO. NO-GC catalyzes the production of the intracellular second messenger cGMP and thereby has a key regulatory function regarding various physiological processes. NO-GC is made up of one β subunit and one α subunit. On the protein level, there are two α subunits (α1 and α2) and one β subunit (β...
متن کاملGuanylyl cyclase sees the light
Cyclic guanosine monophosphate (cGMP) is a critical second messenger that regulates cardiovascular function and vision in humans. Two recent papers, including one in BMC Structural Biology, have revealed atomic structures of the enzymes that catalyze the synthesis of cGMP providing new clues about the molecular basis of substrate specificity and allosteric regulation in nucleotide cyclases.
متن کاملCharacterization of a cGMP-response element in the guanylyl cyclase/natriuretic peptide receptor A gene promoter.
Previous studies have shown that atrial natriuretic peptide (ANP) can inhibit transcription of its receptor, guanylyl cyclase A, by a mechanism dependent on cGMP and have suggested the presence of a putative cGMP-response element (cGMP-RE) in the Npr1 gene promoter. To localize and characterize the putative cis-acting element, we have subcloned a 1520-bp fragment of the rat Npr1 promoter in an ...
متن کاملRapid desensitization of the nitric oxide receptor, soluble guanylyl cyclase, underlies diversity of cellular cGMP responses.
A major receptor for nitric oxide (NO) is the cGMP-synthesizing enzyme, soluble guanylyl cyclase (sGC), but it is not known how this enzyme behaves in cells. In cerebellar cells, NO (from diethylamine NONOate) increased astrocytic cGMP with a potency (EC(50) </= 20 nM) higher than that reported for purified sGC. Deactivation of NO-stimulated sGC activity, studied by trapping free NO with hemogl...
