Abstract

The native cell membrane nanoparticles (NCMN) system utilizes membrane-active polymers specifically designed and optimized to extract and stabilize membrane proteins in the form of NCMN particlesfor biochemical and biophysical characterization. The NCMN system is a genuine and advanced detergent-free approach inspired by the membrane activity of the styrene–maleic acid copolymers (SMA), distinguishing it from the nanodisc technology, Salipro technology, and Peptidisc technology. This review introduces the current advancements in the NCMN system, including the development of NCMN polymers, the application of the NCMN system for single-particle cryo-EM analysis, and the functional characterization of membrane proteins.

期刊介绍： Current Opinion in Structural Biology (COSB) aims to stimulate scientifically grounded, interdisciplinary, multi-scale debate and exchange of ideas. It contains polished, concise and timely reviews and opinions, with particular emphasis on those articles published in the past two years. In addition to describing recent trends, the authors are encouraged to give their subjective opinion of the topics discussed. In COSB, we help the reader by providing in a systematic manner: 1. The views of experts on current advances in their field in a clear and readable form. 2. Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications. [...] The subject of Structural Biology is divided into twelve themed sections, each of which is reviewed once a year. Each issue contains two sections, and the amount of space devoted to each section is related to its importance. -Folding and Binding- Nucleic acids and their protein complexes- Macromolecular Machines- Theory and Simulation- Sequences and Topology- New constructs and expression of proteins- Membranes- Engineering and Design- Carbohydrate-protein interactions and glycosylation- Biophysical and molecular biological methods- Multi-protein assemblies in signalling- Catalysis and Regulation
