The CFTR protein is known to acts as a chloride (Cl -) channel expressed in the exocrine glands of several body systems where it also regulates other ion channels, including the epithelial sodium (Na +) channel (ENaC) that plays a key role in salt absorption.

By understanding how the protein is made, scientists have been able to develop treatments that target the protein and restore its function. The location of the CFTR protein, which is found in several organs, determines where the symptoms of CF occur. The chloride is derived from the efflux of chloride through CFTR. The CFTR protein also regulates the function of other channels, such as those that transport positively charged particles called sodium ions across cell membranes.

Groman JD, Meyer ME, Wilmott RW, Zeitlin PL, Cutting GR. Unique to CFTR is an additional regulatory (R) region, as well as long N- and C-terminal extensions about 80 and 30 residues in length, respectively ( Hunt et al., 2013 ). In: Adam MP, Everman DB, Mirzaa GM, Pagon RA, Wallace SE, CFTR functions as an ATP-gated, phosphorylation-regulated Cl- channel that mediates agonist-stimulated apical membrane epithelial Cl- and bicarbonate secretion and also regulates a variety of other transport proteins and cellular processes. 2005 Apr;39(4 Suppl 2):S70-7. FOIA CFTR folding is intrinsically complex and involves insertion of 12 transmembrane helices into the lipid bilayer, individual folding of soluble domains, and assembly of these domains into the. Normal CFTR facilitates the transport of adenosine triphosphate (ATP), an energy-carrying molecule, to the outside of the cell, activating ORCC. Other respiratory problems, including several conditions that partially block the airways and interfere with breathing, are also associated with CFTR mutations.

They obtained thousands of detailed data sets from these, and were able to fit all this into coherent structural models, the best of which are below 3 resolution. Epithelial cells are composed of two membranes with distinct functions depending on the tissue and on their ion channels, exchangers, cotransporters, or pumps.

Structural studies of the cystic fibrosis transmembrane conductance regulator (CFTR) protein are critical to understand molecular mechanisms involved in gating of the apical anion channel as well as the way in which the gating is regulated, especially by the regulatory region (R region). Men with congenital bilateral absence of the vas deferens are unable to father children (infertile) unless they use assisted reproductive technologies.

The airways are covered with a thin, layer of liquid called airway surface liquid (ASL) and a mucus gel layer. As shown in Figure 2, the CFTR plays a major role in electrolyte and fluid secretion and absorption.

Derek Lowes commentary on drug discovery and the pharma industry. This mutation is caused by a deletion of three nucleotides (CTT) in the CFTR gene, which codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The CFTR gene is transcribed into a single strand of RNA within the cell nucleus (2); regions that are not needed to make the protein are spliced out, producing the final messenger RNA (mRNA) (3).

CFTR is a 1480-residue long membrane protein, with the typical ABC transporter architecture of 2 TMDs, and 2 NBDs ( Higgins, 1992 ). While the basolateral membrane is in contact with the interstitial tissue, the apical membrane is in contact with the external environment and thus also acts as a barrier to prevent potential pathogens or toxic compounds from reaching the bloodstream.
