WebJan 12, 2024 · Cystic fibrosis transmembrane conductance regulator (CFTR) protein maintains the balance of salt and water on many surfaces of the body. CFTR protein is an ion channel that is shaped like a tunnel, with a gate through which chloride ions flow out of the cells, attract water and maintain the right consistency of mucus and other fluids in the … WebThe CFTR gene is a protein that functions as a chloride channel. A chloride channel helps maintain the proper balance of salt and water within a cell. A mutation in CFTR causes a dysfunction of the salt and water balance. This causes dehydration of the secretions (thick mucous) and excessive loss of salt in sweat. What is a carrier?
