CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): abundance and location was examined in the gills of Atlantic salmon (Salmo salar) during seawater acclimation and smolting. Insulin is one of the regulators involved in Na+ reabsorption in kidney. Immunocytochemical studies of the Na-K-Cl cotransporter of shark kidney. Blocking apical NKCC2, but not basolateral NKCC1, by bumetanide inhibited secretagogue-induced gastric acid secretion, during which the membrane trafficking of NKCC2 may be necessary. Two variations of the Na-K-2Cl symporter exist and are known as NKCC1 and NKCC2. The purpose of this study is to understand the regulation of NKCC2 as a candidate for Na+ movement across the kidney cell in response . Later in development expression of NKCC1 is reduced, while expression of a KCC2 K-Cl cotransporter increased, thus bringing internal chloride concentration in neurons down to adult values.[7]. Na(+)-K(+)-2Cl(-) cotransporter abundance and location was examined in the gills of Atlantic salmon (Salmo salar) during seawater acclimation and smolting. NKCC proteins are membrane transport proteins that transport sodium (Na), potassium (K), and chloride (Cl) ions across the cell membrane. Na +-K +-2Cl-cotransporter (NKCC) is expressed at exceptionally high levels in gastric parietal cells. The energy required to move solutes across the cell membrane is provided by the electrochemical gradient of sodium. Status. Surface expression in response to cAMP. Background.

In euryhaline fish, NKCC is important in maintaining a plasma osmolarity of ~300 mOsmol/l NKCC2 regulation is poorly understood because of its restricted distribution and difficulties with its expression in mammalian cell cultures. The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. Increased NKCC2 activity aids in water reabsorption in the collecting duct through aquaporin 2 channels by creating a hypo-osmotic filtrate. Here, we investigated the cotransporters' functional dependence on membrane rafts. This site needs JavaScript to work properly. The role of NKCC2 is essential for renal volume regulation. [1] In humans there are two isoforms of this membrane transport protein, NKCC1 and NKCC2, encoded by two different genes (SLC12A2 and SLC12A1 respectively). Many erythrocyte processes and pathways, including glycolysis, the pentose phosphate pathway (PPP), KCl cotransport, ATP release, Na+/K+-ATPase activity, ankyrin-band 3 interactions, and nitric oxide (NO) release, are regulated by changes in O2 pressure that occur as a red blood cell (RBC) transits between the lungs and tissues. furosemide, bumetanide and torasemide) compete with chloride ions on this transporter to inhibit sodium . It thus serves both in sodium absorption and in tubuloglomerular feedback. Forbush B The Journal of biological chemistry 278.29 (2003 Jul 18): 26946-51. The bumetanide-sensitive Na(+)-K(+)-2Cl(-) cotransporter NKCC2, located in the thick ascending limb of Henle's loop, plays a critical role in the kidney's ability to concentrate urine. Found insideThe text presents as well how the study of the kidney and body fluids have captured the interest of physiologists and other individuals interested in this discipline. We undertook the present study to determine whether the O 2 dependence of Na + /K + /2Cl - cotransport (catalyzed by Na + /K + /2Cl - cotransporter 1 [NKCC1]) might similarly originate from competition between deoxyHb and a protein involved in NKCC1 regulation for a common binding site on band 3. Thus, we sought in this study to determine if the distribution of NKCC1 correlates with that of AQP1 in the leptomeningeal vasculature. The Na & Cl concentration gradients favor the net reabsorption of sodium and chloride by the electroneutral Na/K/2Cl cotransporter (Hropot et al, 1985). It was found to encode 1055 amino acids containing conserved AA-permease and SLC12 motifs. Since NKCC proteins use sodium's gradient, their activity is indirectly dependent on ATP; for this reason, NKCC proteins are said to move solutes by way of secondary active transport. 2010;298:C85-97 pubmed publisher Hearing Res. 30 The alteration in ion transport within the TAL significantly affects the Ca 2+ and Mg 2 .

Adverse effects of site 1 diuretics. Western blots revealed three bands centered at 285, 160, and 120 kDa. Unreviewed - Annotation score: Annotation score:1 out of 5. The downregulation of NKCC2 and VAMP2 may be related to the reduced gastric acid secretion induced by LPS. The outward Cl - gradient that provides the driving force for Cl - efflux might be generated and maintained by the Na +, K +, 2Cl - cotransporter (NKCC) that keeps intracellular Cl - concentration above electrochemical equilibrium. The Na-K-2Cl Cotransporter is vital in salt secretion in secretory epithelia cells along with renal salt reabsorption. In order to elucidate its function, and regulatory mechanisms, in salinity acclimation, the complete cDNA sequence of NKCC (4218 bp) from Portunus trituberculatus (PtNKCC) was first cloned and characterized. Cotransporters, WNKs and hypertension: an update. Using the gradient for Na + generated by the Na +-K +-ATPase pump, NKCC1 cotransporter protein conveys Na +, K +, and Cl − into cells under physiological conditions (9-11). The thick ascending limb of the loop of Henle begins at the deeper portion of the renal outer medulla.

We undertook the present study to determine whether the O2 dependence of Na+/K+/2Cl- cotransport (catalyzed by Na+/K+/2Cl- cotransporter 1 [NKCC1]) might similarly originate from competition between deoxyHb and a protein involved in NKCC1 regulation for a common binding site on band 3. Inhibition of NKCC1, as with furosemide or other loop diuretics, can result in deafness. Secretagogue-dependent and -independent transport of zinc hydration forms in rat parietal cells. The O2 dependence of glycolysis, PPP, and ankyrin-band 3 interactions (affecting RBC rheology) are controlled by O2-dependent competition between deoxyhemoglobin (deoxyHb), but not oxyhemoglobin (oxyHb), and other proteins for band 3. Immunocytochemical studies of the Na-K-Cl cotransporter of shark kidney. Upon histamine stimulation, the majority of NKCC2 was targeted to the apical membrane in the gastric mucosa and in primary cultured parietal cells. With higher internal chloride concentrations, outward driving force for this ions increases, and thus channel opening leads to chloride leaving the cell, thereby depolarizing it. Na:K:2Cl cotransporter (NKCC) of intestinal epithelial cells. The outward Cl - gradient that provides the driving force for Cl - efflux might be generated and maintained by the Na +, K +, 2Cl - cotransporter (NKCC) that keeps intracellular Cl - concentration above electrochemical equilibrium. The Na +-K +-2Cl − cotransporter was colocalized with Na +-K +-ATPase to chloride cells on both the primary filament and secondary lamellae. A dramatic upregulation (15- to 20-fold) of acinar Na(+)-K(+)-2Cl- cotransporter activity was induced by muscarinic, alpha 1-adrenergic and peptidergic stimuli.
