Fig. 2: Structures of α7nAChR TMD + ICD.
From: Structures of highly flexible intracellular domain of human α7 nicotinic acetylcholine receptor
a Side view of a pentameric structure with marked residues (Cα atom shown in VDW) for measuring ICD dimensions. b A single subunit color-coded with secondary structures (cyan for α helix, blue for 310-helix, orange for turn, and silver for coil). c A bottom view of the pentameric structure. d Intensity (peak height) distribution of TMD + ICD residues obtained from a HNCOCA NMR spectrum. Missing bars are due to overlapping residues or prolines. Note that the distinctly high and low intensities for residues in loop regions and TMD or long ICD helices are indication of faster and slower motions, respectively. Source data are provided as a Source Data file.
