Producing intact recombinant membrane proteins for structural studies is an inherently challenging task due to their requirement for a cell-lipid environment. Most of the procedures developed involve isolating the protein by solubilization with detergent and further reconstitutions into artificial membranes. These procedures are highly time consuming and suffer from further drawbacks, including low yields and high cost. We describe here an alternative method for rapidly obtaining recombinant cell-surface membrane proteins displayed on extracellular vesicles (EVs) derived from cells in culture. Interaction between these membrane proteins and ligands can be analyzed directly on EVs. Moreover, EVs can also be used for protein structure determination or immunization purposes.

细胞外囊泡作为研究细胞表面膜蛋白的平台

生产用于结构研究的完整重组膜蛋白是一项固有的挑战性任务,因为它们需要细胞-脂质环境。大多数开发的程序涉及通过用去污剂溶解来分离蛋白质,并进一步重组为人造膜。这些程序非常耗时,并且还有其他缺点,包括低产量和高成本。我们在这里描述了一种替代方法,用于快速获得在来自培养细胞的细胞外囊泡 (EV) 上展示的重组细胞表面膜蛋白。这些膜蛋白和配体之间的相互作用可以直接在 EV 上进行分析。此外,EV 还可用于蛋白质结构测定或免疫目的。
