蛋白质组学分析已被证明是一个重要的工具,了解遗传性疾病的复杂性,如囊性纤维化(CF),通过定义与野生型和突变蛋白相关的细胞蛋白质环境(蛋白质组)。蛋白质组学筛选鉴定了CF跨膜传导调节因子(CFTR)的蛋白质组,为研究CFTR生理功能的关键组分提供了基础信息。同时,CFTR突变体的小分子校正剂的高通量筛选为治疗提供了有希望的候选者。大多数CF病例是由核苷酸缺失(ΔF508 CFTR; >75%)引起的,导致CFTR错误折叠,或插入提前终止密码子(约10%),导致mRNA不稳定和功能失调的截短CFTR水平降低。在这篇文章中,我们回顾了蛋白质组学筛选的最新结果,在确定最常见的CFTR突变体校正的发展,并评论如何整合从这些研究中获得的知识可能有助于找到治愈CF和其他一些遗传疾病。
Proteomic analysis has proved to be an important tool for understanding the complex nature of genetic disorders, such as cystic fibrosis (CF), by defining the cellular protein environment (proteome) associated with wild-type and mutant proteins. Proteomic screens identified the proteome of CF transmembrane conductance regulator (CFTR), and provided fundamental information to studies designed for understanding the crucial components of physiological CFTR function. Simultaneously, high-throughput screens for small-molecular correctors of CFTR mutants provided promising candidates for therapy. The majority of CF cases are caused by nucleotide deletions (ΔF508 CFTR; >75%), resulting in CFTR misfolding, or insertion of premature termination codons (~10%), leading to unstable mRNA and reduced levels of truncated dysfunctional CFTR. In this article, we review recent results of proteomic screens, developments in identifying correctors for the most frequent CFTR mutants, and comment on how integration of the knowledge gained from these studies may aid in finding a cure for CF and a number of other genetic disorders.
