Membrane proteins (MP) are stable in their native lipid environment. To enable structural and functional investigations, MP need to be extracted from the membrane. This is a critical step that represents the main obstacle for MP biochemistry and structural biology. General guidelines and rules for membrane protein solubilization remain difficult to establish. This review aims to provide the reader with a comprehensive overview of the general concepts of MP solubilization and stabilization as well as recent advances in detergents innovation. Understanding how solubilization and stabilization are intimately linked is key to facilitate MP isolation toward fundamental structural and functional research as well as drug discovery applications. How to manage the tour de force of destabilizing the lipid bilayer and stabilizing MP at the same time is the holy grail of successful isolation and investigation of such a delicate and fascinating class of proteins.
膜蛋白(MP)在其天然脂质环境中稳定。为了进行结构和功能研究,需要从膜中提取 MP。这是一个关键步骤,也是 MP 生物化学和结构生物学的主要障碍。通用的膜蛋白溶解指南和规则仍然难以建立。本综述旨在为读者提供膜蛋白溶解和稳定的一般概念的全面概述,以及去污剂创新的最新进展。了解溶解和稳定是如何紧密联系的,对于促进 MP 的分离,进行基础结构和功能研究以及药物发现应用至关重要。如何同时破坏脂质双层并稳定 MP,这是成功分离和研究如此脆弱而迷人的蛋白质的关键。
