Compartmentalized Regulation of CFTR Chloride Channel Function in Apical Epithelia
Author(s): Chunying LiChunying Li
The cystic fibrosis transmembrane conductance regulator (CFTR), a chloride channel that is located primarily at the apical plasma membrane of polarized epithelial cells, plays a crucial role in transepithelial fluid homeostasis. Tight regulation of CFTR function is critical, as either hypofunctioning or hyperfunctioning of CFTR activity may result in life-threatening disorders. Accumulating evidence has suggested that the regulation of CFTR channel function is highly compartmentalized, i.e., CFTR function is tightly fine-tuned in localized microdomains, in which CFTR-containing multiprotein complexes play a critical role. A growing number of proteins has been reported to interact directly or indirectly with CFTR, implying that CFTR is coupled functionally and/or physically to a wide variety of interacting partners including ion channels, receptors, transporters, scaffolding proteins, ..
