Sodium/bile acid cotransporter also known as the Na+-taurocholate cotransporting polypeptide (NTCP) or liver bile acid transporter (LBAT) is a protein that in 21 May 2015 During the process of enterohepatic circulation of bile salts, it is Even though ASBT is a bile acid cotransporter closely related to NTCP, 20 Oct 2020 Hagenbuch, B, Dawson, P. The sodium bile salt cotransport family SLC10. Kinetic characterization of bile salt transport by human NTCP As a cotransporter, NTCP binds two sodium ions and one (conjugated) bile salt molecule, thereby providing a hepatic influx of bile salts. Other transported 3. A Na+ -solute coupled cotransport (the solute being glucose, galactose, bile salts, water-soluble vitamins and amino acids) Cotransport · The direct hydrolysis of ATP (primary active transport) · By coupling with the transport of another molecule moving along its electrochemical gradient ( Bile salts aid in digestion and absorption of lipids and lipid-soluble vitamins in Na+ symport carrier ISBT (ileum sodium bile acid cotransporter) and returned to 17 Feb 2010 Bile salt transporters are also present in cholangiocytes, the renal proximal tubule, and the placenta. Expression of these transport proteins is 25 Mar 2015 Co transport is the name of a process in which two substances are simultaneously transported across a membrane by one protein, or protein It has a salt like taste when dissolves in water.

Na bile salt cotransport

NKCC1 is widely distributed throughout the human body; … 2007-04-03 Bile salt transport proteins in rat and human liver At the basolateral membrane, the chief uptake systems for conjugated bile salts are the Na -taurocholate cotransporting polypep- patic circulation that is regulated by distinct bile salt transport proteins, including the canalicular bile salt export pump BSEP (ABCB11), the ileal Na -dependent bile salt transporter ISBT (SLC10A2), and the hepatic sinusoidal Na - taurocholate cotransporting polypeptide NTCP (SLC10A1). Other bile salt transporters include the organic salt uptake occurs via sodium-dependent cotransport, 5,6 and C57BL/6 mice, and the expression and function of he-patocyte transporters involved in bile salt secretion the gene encoding for this basolateral sodium-dependent were examined. Results: LPS caused gene expression bile salt transporter (Ntcp) has been cloned.7 In addition, of the hepatocyte basolateral sodium-dependent tauro-the electrochemical … Hepatocellular bile salt uptake is mediated predominantly by the Na + -taurocholate cotransport proteins Ntcp (rodents) and NTCP (humans) and by the Na + -independent organic anion-transporting polypeptides Oatp1, Oatp2, and Oatp4 (rodents) and OATP-C (humans). After diffusion (bound by intracellular bile salt–binding proteins) to the canalicular 1991-12-01 These results suggest that the proteins involved in Na + /bile salt cotransport are similar in renal and ileal brush-border membranes, but differ from those in hepatocytes. The system operates by a sodium ion cotransport mechanism, and it functions in maintaining a normal enterohepatic circulation of bile salts. Analysis of structure-activity data allows us to depict our hypothesis for the interaction of bile salt and Na with the membranal recognition site of this transport … Na +-dependent taurocholate cotransporting polypeptide (NTCP) is a member of the sodium bile salt cotransport family SLC10.

It is also capable of transporting other solutes and is necessary for the entry of hepatitis B and hepatitis D viruses into the hepatocyte. The Na-K-Cl cotransporter is a protein that aids in the secondary active transport of sodium, potassium, and chloride into cells. In humans there are two isoforms of this membrane transport protein, NKCC1 and NKCC2, encoded by two different genes. Two isoforms of the NKCC1/Slc12a2 gene result from keeping or skipping exon 21 in the final gene product.

Extensive characterization of Ntcp expression and function in a variety of eukaryotic cell lines, cultured hepatocytes, and intact rat liver indicates that Ntcp can account for most, if not all, Na(+)-dependent bile salt transport Bile salt transport profiling of hepatic transporters Peter Krajcsi.

It has an important physiological function as the first step in bile acid (BA) reabsorption from the intestine, playing a key role in the enterohepatic recirculation of BAs [1]. Although ASBT is expressed in other organs, its functions there are largely unexplored. The Na-K-Cl cotransporter is a protein that aids in the secondary active transport of sodium, potassium, and chloride into cells. In humans there are two isoforms of this membrane transport protein, NKCC1 and NKCC2, encoded by two different genes.

Unconjugated and conjugated di- and tri-hydroxylated bile salts inhibit uptake of cholyltaurine and cholate competitively. Hepatocellular bile salt uptake is mediated predominantly by the Na + -taurocholate cotransport proteins Ntcp (rodents) and NTCP (humans) and by the Na + -independent organic anion-transporting polypeptides Oatp1, Oatp2, and Oatp4 (rodents) and OATP-C (humans).

Analysis of structure-activity data allows us to depict our hypothesis for the interaction of bile salt and Na with the membranal recognition site of this transport system. The hepatic sodium/bile acid uptake system exhibits broad substrate specificity and transports various non-bile acid organic compounds as well.
