Abstract

The cystic fibrosis transmembrane conductance regulator (CFTR) is a Cl-selective anion channel expressed in epithelial tissues. Mutations in CFTR lead to the genetic disease cystic fibrosis (CF). Within each epithelial cell, CFTR interacts with a large number of transient macromolecular complexes, many of which are involved in the trafficking and targeting of CFTR. Understanding how these complexes regulate the trafficking and fate of CFTR, provides a singular insight not only into the patho-physiology of cystic fibrosis, but also provides potential drug targets to help cure this debilitating disease.

摘要

囊性纤维化跨膜传导调节因子(CFTR)是一种在上皮组织中表达的Cl⁻选择性阴离子通道。CFTR的突变会导致遗传性疾病囊性纤维化(CF)。在每个上皮细胞内,CFTR与大量瞬时大分子复合物相互作用,其中许多复合物参与CFTR的运输和靶向。了解这些复合物如何调节CFTR的运输和命运,不仅能为囊性纤维化的病理生理学提供独特见解,还能为帮助治愈这种使人衰弱的疾病提供潜在的药物靶点。
