 Quantifoil R2/1 COPPER 200 CARBON HOLEY GLOW DISCHARGE ETHANE
4 microliters of splayed axoneme sample were applied to glow-discharged Quantifoil R2/2 Cu grids. After removing excess liquid by blotting the grid from the backside with Whatman filter paper for 2-3 s, the grid was immediately plunge-frozen in liquid ethane using a home-made plunge freezer..

particles containing RS3 were manually picked (using the conserved spacing of RSs as guide) centering on the A-tubule of the DMT
 cryoSPARC 3.3.1 PHASE FLIPPING AND AMPLITUDE CORRECTION For the RS3 head, neck, and stalk, the AlphaFold2 models of mouse were used.
For the RS3 base, the PDB entry 8J07 was used as starting.
