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 کاملGlycosylation of human receptor guanylyl cyclase C
Background Post translational modifications regulate several signalling pathways and glycosylation is emerging as a key player in this regulatory process. Glycosylation of cell surface receptors modulate the downstream signalling pathway and when altered causes a change in the normal physiology of the cell [1]. Guanylyl cyclase C (GC-C) belongs to a group of membrane bound receptors that produc...
متن کاملTitle: The Role of Guanylyl Cyclase C During Intestinal Adaptation
Introduction: Following a proximal small bowel resection (SBR), the intestine adapts by increased crypt depth and villus height compared to sham operated mice (transection and reanastomosis only). The epidermal growth factor receptor (EGFR) is a known mediator of intestinal adaptation and results in activation of the GTPase Rac. This activates PAK (p21-activated protein kinase) which may activa...
متن کاملOlfaction and Odor Discrimination Are Mediated by the C. elegans Guanylyl Cyclase ODR-1
Animals in complex environments must discriminate between salient and uninformative sensory cues. Caenorhabditis elegans uses one pair of olfactory neurons called AWC to sense many different odorants, yet the animal can distinguish each odorant from the others in discrimination assays. We demonstrate that the transmembrane guanylyl cyclase ODR-1 is essential for responses to all AWC-sensed odor...
متن کاملPharmacological characterization of receptor guanylyl cyclase reporter cell lines
Receptor guanylyl cyclases are implicated in a growing number of pathophysiologies and, therefore, represent an important target class for drug development. We report here the generation and pharmacological characterization of three particulate guanylyl cyclase (pGC) reporter cell lines. Plasmid constructs encoding the natriuretic peptide receptors GC-A and GC-B, and the heat-stable enterotoxin...
