Cystic fibrosis transmembrane conductance regulator

Cystic fibrosis transmembrane conductance regulator ( CFTR) is a membrane protein and chloride channel in vertebrates that is encoded by the CFTR gene. The CFTR gene codes for an ABC transporter -class ion channel protein that conducts chloride ions across epithelial cell membranes The cystic fibrosis transmembrane conductance regulator (CFTR) is defective in cystic fibrosis (CF). This protein is a channel that sits on the surface of cells and transports chloride and other molecules, such as bicarbonate. The gene that encodes the CFTR protein, which is also called CFTR, is located on chromosome 7 The CFTR gene provides instructions for making a protein called the cystic fibrosis transmembrane conductance regulator. This protein functions as a channel across the membrane of cells that produce mucus, sweat, saliva, tears, and digestive enzymes. The channel transports negatively charged particles called chloride ions into and out of cells

CFTR proteins help maintain fluid balance The cystic fibrosis transmembrane conductance regulator (CFTR) gene tells our cells how to make CFTR proteins. 1 This gene provides the instructions that get passed to other parts of the cell where the CFTR protein is made.. Once CFTR proteins have been processed and folded correctly inside the cell, they are transported to the cell surface (membrane) CF gene is on chromosome seven (instructs the cell to make the CFTR protein that forms the transmembrane chloride channel) However the sequence of bases in the DNA tells the cell which amino acids to link together to make the CFTR protein Each gene is a sequence of bases on a DNA molecule coding for a sequence of amino acids in a polypeptide chai The cystic fibrosis transmembrane conductance regulator (CFTR) is a 1480 amino acid membrane bound glycoprotein with a molecular mass of 170,000. It is a member of the ATP binding cassette (ABC) superfamily of proteins which includes several clinically important proteins such as P-glycoprotein (P-gp), multidrug resistance associated protein and the TAP transporters

Characteristics of CFTR gene

The CFTR gene produces the CFTR protein, which regulates the chloride ion content of epithelial cells that line the nasal cavity, lungs, and stomach. These cells secrete fluids such as sweat, mucus, and tears, which normally are thin and watery The encoded protein functions as a chloride channel, making it unique among members of this protein family, and controls ion and water secretion and absorption in epithelial tissues. Channel activation is mediated by cycles of regulatory domain phosphorylation, ATP-binding by the nucleotide-binding domains, and ATP hydrolysis We offer CFTR Peptides and CFTR Proteins for use in common research applications: Blocking/Neutralizing, Control, ELISA, Protein Array, Western Blot.

  3. Mutations in the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR) cause cystic fibrosis (CF) (Collins, 1992). Over 500 naturally occurring mutations have been identified in CF gene which are located in all of the domains of the protein (Kerem et al., 1990; Mercier et al., 1993; Ghanem et al., 1994; Fanen et al., 1992; Ferec et al., 1992; Cutting et al., 1990)
  4. CFTR (cystic fibrosis transmembrane conductance regulator) is an integral membrane protein that functions as an epithelial Cl − channel, which is rendered defective by inherited gene mutations in patients with cystic fibrosis (Riordan et al. 1989).Its function underlies fluid secretion in the airways, sweat ducts, pancreatic duct, and vas deferens, and it mediates the excessive intestinal.
  5. These are substances that affect specific mutations or groups of mutations of the CFTR gene. In general, they can be divided into CFTR correctors and potentiators, where CFTR correctors increase the amount of CFTR protein in the cell membrane, while CFTR potentiators improve its function
  6. The CFTR protein itself is regulated at the maturational level by chaperones and SNARE proteins and at the functional level by several protein kinases. Moreover, CFTR functions also as a regulator of other ion channels and of intracellular membrane transport processes. In order to be able to function as a protein with pleiotropic actions, CFTR seems to be linked with other proteins and with the cytoskeleton through interaction with PDZ-domain-containing proteins at the apical pole of the cell
  7. The CFTR inhibitory factor is a protein virulence factor secreted by the Gram-negative bacteria Pseudomonas aeruginosa and Acinetobacter nosocomialis. Discovered at Dartmouth Medical School, Cif is able to alter the trafficking of select ABC transporters in eukaryotic epithelial cells, such as the cystic fibrosis transmembrane conductance regulator, and P-glycoprotein by interfering with the host deubiquitinating machinery. By promoting the ubiquitin-mediated degradation of CFTR, Cif is able t

CFTR protein expression summary - The Human Protein Atla

Cystic fibrosis transmembrane conductance regulator (CFTR) is an ATP-binding cassette (ABC) transporter that functions as a chloride channel. Nucleotide-binding domain 1 (NBD1), one of two ABC domains in CFTR, also contains sites for the predominant CF-causing mutation and, potentially, for regulatory phosphorylation Some people make no CFTR protein at all. Amphotericin B is an antifungal medication that can form a channel to allow molecules in and out of the cell. To test whether amphotericin B can replace the function of defective CFTR protein, a team led by Dr. Martin D. Burke at the University of Illinois in Champaign tested the small molecule in an. The susceptibility of CFTR toward the expression background is also demonstrated by the variable phenotypes of ΔF508 CF mouse models, which exhibit prominent differences in cftr transcript and protein expression (53 - 55), resulting either in a CF phenotype that corresponds to a null mutation (53, 54) or in some residual chloride channel. Cystic fibrosis (CF) is an autosomal recessive disease caused by mutations in the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR) anion channel. The most common CF-associated mutation is Δ F508 , which deletes a phenylalanine in position 508. In vitro studies indicate that the resultant protein, CFTR-ΔF508, is misprocessed, although the in vivo consequences of. The human ATP-binding cassette (ABC) protein CFTR (cystic fibrosis transmembrane conductance regulator) is a chloride channel, whose dysfunction causes cystic fibrosis.
