Abstract: The application belongs to the technical field of biotechnology, and specifically relates to a site-specifically labeled transmembrane protein nanodisc, and a preparation method and use thereof. The preparation method for a site-specifically labeled transmembrane domain (TMD) as provided in this disclosure involves introducing a cysteine mutation into the TMD gene of a transmembrane protein. This mutated TMD is then conjugated with a chemical compound to achieve site-specifical labeling. Subsequently, the site-specifically labeled TMD and an extracellular domain (ECD) are expressed separately. The TMD is incorporated into a nanodisc, which closely mimics the physiological environment, and then ligated to the ECD. This process results in the formation of a site-specifically labeled transmembrane protein nanodisc.
