CFTR (Cystic Fibrosis Transmembrane Conductance Regulator)

CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) is a protein found in cell membranes that helps regulate the transport of chloride ions across cells, which is essential for maintaining the balance of salt and water in tissues. Proper functioning of CFTR is crucial for producing thin, healthy mucus in organs like the lungs and digestive system. In cystic fibrosis, mutations in the CFTR gene impair this protein's function, leading to thick, sticky mucus buildup that causes respiratory and digestive issues. Understanding CFTR is key for developing treatments for cystic fibrosis and related conditions.
