Direct cell extraction of membrane proteins for structure-function analysis

Sci Rep. 2023 Jan 25;13(1):1420. doi: 10.1038/s41598-023-28455-w.

Abstract

Membrane proteins are the largest group of therapeutic targets in a variety of disease areas and yet, they remain particularly difficult to investigate. We have developed a novel one-step approach for the incorporation of membrane proteins directly from cells into lipid Salipro nanoparticles. Here, with the pannexin1 channel as a case study, we demonstrate the applicability of this method for structure-function analysis using SPR and cryo-EM.
