BRIL)β2 nicotinic acetylcholine receptor (nAChR): The design of expression constructs and protein expression are as follows—all human α4 (Uniprot P43681) and β2 (Uniprot P17787) constructs were synthesized at Genewiz and sub-cloned into pcDNA3.1(+) (Life Technologies). They include the signal peptide and encode residues 1–338 and 556–601 of the α4 subunit, and residues 1–326 and 417–477 of the β2 subunit (numbering reflects mature protein after signal peptide cleavage). A Glu-Arg linker was inserted in the MX–M4 junction, between Phe559 and Ser560 in the α4 subunit and between Gln420 and Ser421 in the β2 subunit. For purification purposes, a Strep-tag was inserted at the C terminus of the β2 subunit preceded by a Ser-Ala linker. Additionally, BRIL-fusion constructs were designed (Supplementary Table 6) for both the α4 and β2 subunits. Endotoxin free plasmid DNA was generated for all constructs (Qiagen). Kabsch, W.

Fabs enable single particle cryoEM studies of small proteins. Structure 20, 582–592 (2012). The thermal stability of the membrane proteins (wt YiiP and the YiiP-BRIL chimera) was determined using the thiol-specific fluorochrome N-[4-(7-diethylamino-4-methyl-3-coumarinyl)phenyl]maleimide (CPM) 18 in a HORIBA Fluorolog-3 fluorimeter.

We and others have shown that antibodies (Fabs) can be powerfully used as fiducial marks by adding mass (50 kDa) to the particle and assisting in its orientation 6, 7, 8, 9, 10, 11, 12. Fabs have been generated by traditional hybridoma approaches, but generally recombinant-based library display methods, such as phage, yeast or ribosome display are more broadly used 13, 14, 15. These display methods allow for the flexibility to tune affinities, epitopes and conformational state 16, 17. However, the use of Fabs remains restricted because they have to be produced for each individual system. While the display methods are in common practice, they are not yet turnkey for generation of high-affinity binders of the type needed for structural analyses, especially for membrane proteins.

BRIL)β2-nAChR/BAK5 complex: 3.5 μL of 3 mg/ml α4(BRIL)β2-nAChR/BAK5 complex was applied to glow-discharged (0.39 mbar, −30 mA, 30 secs, in air) Quantifoil R1.2/1.3 200 mesh Au grids and vitrified using a Vitrobot Mark IV (ThermoFisher Scientific) at 100% RH and 4 °C. Frozen grids were loaded into a Titan Krios G2 transmission electron microscope (ThermoFisher Scientific) operating at 300 keV equipped with a Gatan K2 Summit direct electron detector. Images were recorded using SerialEM in super-resolution mode at a pixel size of 0.53 Å over a defocus range of −1.2 to 2.4 μm. Data were collected using a dose rate of 5.9 electrons per physical pixel per second, for 10.5 s total exposure, dose fractionated at 0.3 sec/frame (35 frames) corresponding to a total dose of 52 e −/Å 2.
