The ATP-binding cassette (ABC) transporter family includes the CFTR (Cystic Fibrosis Transmembrane Conductance Regulator), which functions as a channel for small anions like chloride and bicarbonate. Two identical halves of CFTR, each with a transmembrane (TMD) and a nucleotide binding domain (NBD), make up the entire structure. The cytosolic regulatory (R) domain of CFTR is phosphorylated, and ATP is bound and hydrolyzed at two NBDs to control CFTR activity.
Although CFTR is expressed in a wide variety of cell types throughout the body, it is primarily found in the secretory serous cells of the submucosal glands in the airways. The cytosolic nucleotide binding domains of CFTR are coupled with the transmembrane (TM) domains to form the pathway for anion permeation, and ATP binding and hydrolysis on these domains controls transitions between open and closed states. CFTR activity is typically tightly regulated because dysregulation can result in fatal conditions like cystic fibrosis and secretory diarrhoea.
