Among the many medically significant proteins in the ABC transporter family are the cystic fibrosis transmembrane regulator (CFTR) and a multidrug resistance protein (MDR) called P-glycoprotein. Answer: Normally, when there is too little water in the mucus lining the epithelial cells of the airways (e.g. The pancreatic duct cells also secrete bicarbonate into the intestine to neutralize stomach acid via the CFTR channel. In people with CF, mutations in the CFTR gene can cause the following problems with the CFTR protein: When any of these problems occur, the chloride ions are trapped inside the cell, and water is no longer attracted to the space outside the cell. Int J Mol Sci. Most of these mutations change single protein building blocks (amino acids) in the CFTR protein or delete a small amount of DNA from the CFTR gene. Hes worked for several major pharmaceutical companies since 1989 on drug discovery projects against schizophrenia, Alzheimers, diabetes, osteoporosis and other diseases. The TMDs form the channel of the CFTR protein, while the NBDs regulate its opening and closure. The CFTR protein reaches the cell surface butchloridetransportthrough the channel is defective. Derek Lowes commentary on drug discovery and the pharma industry. Mucus is a slippery substance that lubricates and protects the lining of the airways, digestive system, reproductive system, and other organs and tissues. Proinflammatory cytokine secretion is suppressed by TMEM16A or CFTR channel activity in human cystic fibrosis bronchial epithelia. Denning GM, Ostedgaard LS, Cheng SH, Smith AE, Welsh MJ. In addition, germs caught in the mucus are no longer expelled from the airway, allowing them to multiply and cause infections. 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. Because the 3-D shape of CFTR is so complex, it was not until early 2017 that the first high-resolution pictures were developed. Each domain has a special function when it comes to transporting chloride through the cell surface.
