整合膜蛋白占人类蛋白质组的约25%。然而,我们对它们的分子生理学的理解仍处于起步阶段。这可以归因于两个因素:膜蛋白的复杂化学性质带来的实验挑战,以及它们的活性与其天然环境之间的关系不清楚。因此,需要采取新的办法来应对这些挑战。质谱的最新发展表明,在无溶剂环境中研究膜蛋白是可能的,并为复杂的相互作用,配体结合和折叠过程提供详细的见解。有趣的是,不仅洗涤剂胶束,而且脂质双层纳米盘或bicelles可以作为膜蛋白在气相中温和去溶剂化的手段。以这种方式,以及通过直接添加脂质,有可能研究不同的膜组分对蛋白质组分的结构和功能的影响,使我们能够将功能数据添加到蛋白质组中最难获得的部分。
Integral membrane proteins comprise ∼25% of the human proteome. Yet, our understanding of their molecular physiology is still in its infancy. This can be attributed to two factors: the experimental challenges that arise from the difficult chemical nature of membrane proteins, and the unclear relationship between their activity and their native environment. New approaches are therefore required to address these challenges. Recent developments in mass spectrometry have shown that it is possible to study membrane proteins in a solvent-free environment and provide detailed insights into complex interactions, ligand binding and folding processes. Interestingly, not only detergent micelles but also lipid bilayer nanodiscs or bicelles can serve as a means for the gentle desolvation of membrane proteins in the gas phase. In this manner, as well as by direct addition of lipids, it is possible to study the effects of different membrane components on the structure and function of the protein components allowing us to add functional data to the least accessible part of the proteome.
