Figure 1. High-resolution solid-state NMR of mammalian TSPO in a lipid bilayer.

Figure 1

(a) Schematic representation of mammalian TSPO embedded into liposomes. Cholesterol is marked in red and cyan, the TSPO-ligand DAA1106 in orange/yellow. (b) CD spectrum of the membrane-embedded mTSPO/DAA1106 complex. (c) High-resolution 13C–13C proton-driven spin diffusion spectrum of mTSPO bound to DAA1106. (d) Secondary structure analysis of liposome-embedded mTSPO in complex with DAA1106. Positive δCα-δCβ values are indicative of α-helix and identify five transmembrane helices and a short cytosolic helix following transmembrane helix I.
