The CFTR chloride channel is one of the most well studied transport proteins in biology. Yet there remain many mysteries about the functional properties and biological roles of this ABC transporter. The Cystic Fibrosis Transmembrane Conductance Regulator addresses a select series of hot' topics that relate to the function of CFTR, and the links between CFTR dysfunction and human disease (i.e., cystic fibrosis). The timeliness of these topics distinguishes this collection from previous volumes of this type. Given the general interest in CFTR, this collection will appeal to a broad readership with interests in CFTR, cystic fibrosis, ion channels and ABC transporters.
