Western blotting for SpCas9 and T7 RNAP was described previously 13 (link). To determine regulation of target protein expression by the TetR- or TetR-DOZI-aptamer system, parasites cultured with 0 nM or 50 nM aTc for 72 h were saponin-lysed, washed with 1 × PBS, and proteins solubilized in lysis buffer containing 4% sodium dodecyl sulfate (SDS) and 0.5% Triton X-114 in 1 × PBS. Protein extracts were mixed with loading buffer containing SDS and dithiothreitol (DTT) and loaded onto Mini-PROTEAN TGX Precast Gels (4–15% gradient; Bio-Rad 4,561,084) in Tris–Glycine buffer. After separation by polyacrylamide gel electrophoresis (PAGE), proteins were transferred to a polyvinylidene fluoride (PVDF) membrane using the Mini Trans-Blot Electrophoretic Transfer Cell system (Bio-Rad) per the manufacturer’s instructions and blocked with 100 mg/mL skim milk in 1 × TBS/Tween 20. PVDF membrane-bound proteins were first probed with mouse anti-HA (1:3000; Sigma, H3663) and rabbit anti-GAPDH (1:5000; Abcam, AB9485) primary antibodies and anti-mouse (1:5000; Thermo Fisher Scientific, 62–6520) and anti-rabbit (1:5000; Cell Signaling, 7074S) horseradish peroxidase (HRP)-conjugated secondary antibodies. Following incubation in SuperSignal West Pico Chemiluminescent substrate (Thermo Fisher Scientific, PI34080), protein blots were imaged and analysed using the ChemiDoc MP System and Image Lab 5.2.0 (Bio-Rad).

The D381C E2 protein (E2) was prepared as previously described.13 (link) D381C is an E2 mutant with a non-native cysteine introduced to the internal cavity of the nanoparticle for site-directed functionalization. Briefly, proteins were expressed in E. coli, cells were lysed, and soluble cell lysates were applied to a HiPrep Q Sepharose anion exchange column (GE Healthcare) followed by a Superose 6 (GE Healthcare) size exclusion column for purification. The purified proteins were analyzed by dynamic light scattering (Zetasizer Nano ZS, Malvern) for size measurements. Electrospray ionization mass spectrometry and SDS-PAGE were performed for molecular weight and purity confirmation. Final protein preparations were stored in 50 mM potassium phosphate at pH 7.4 with 100 mM NaCl at 4°C for short-term and −80°C for long-term storage.
Lipopolysaccharide (LPS), a component of gram-negative bacterial cell walls, is recognized by Toll-like receptor 4 expressing immune cells (e.g. DCs), causing potentially unwanted immune activation. Residual LPS was removed following the method described by Aida and Pabst.51 (link) Briefly, Triton X-114 (Sigma) was added to the purified protein at 1% (v/v), chilled to 4°C, vortexed vigorously, and heated to 37°C. The mixture was then centrifuged at 18,000 × g and 37°C for 30 seconds, and the protein-containing aqueous portion was separated from the detergent. This total process repeated ≥ 8 times. Residual Triton was removed with detergent removal spin columns (Pierce). LPS levels were below 8 EU (0.8 ng) per milligram of E2 protein (LAL ToxinSensor gel clot assay, Genscript), significantly lower than levels that activate DCs in our assays.

Flagellar isolation using the dibucaine method and flagellar amputation by pH shock were performed as previously described by Witman (1986) (link) and Lefebvre (1995) (link), respectively. Isolated flagella were extracted with 1% NP-40 Alternative (EMD) for 20 min on ice, and the suspension was separated by centrifugation into a pellet containing the axonemes and a supernatant consisting of the membrane-plus-matrix. For MS quantitation of BBS1 and IFT81 in the membrane-plus-matrix, the AQUA peptide technique was used (see Quantitative MS and Fig. S4). The membrane-plus-matrix was further separated by sucrose gradient centrifugation (36,000 rpm for 12.5 h at 4°C on an SW41 rotor [Beckman Coulter]), and fractions were analyzed by SDS-PAGE and Western blotting. For phase partitioning, isolated flagella were extracted using 1% Triton X-114 for 20 min on ice; after removal of the axonemes by centrifugation (Witman, 1986 (link)), the supernatant was incubated briefly at 37°C, and phases were separated by centrifugation (3,300 g for 10 min at RT). The AP was treated with 1% Triton X-114, the DP was diluted with buffer, and the phase separation was repeated to yield the final APs and DPs.

The design-specific staple strands were purchased from IDT Technologies in 250 μM scale. The sequence of the staple strands and the design is reported in the Supplementary Information. The p7308 scaffold strand was produced from M13 phage replication in Escherichia coli and was endotoxin-purified using Triton X-114 as described previously13 (link).
For the synthesis of DNs, 10 nM p7308 scaffold was mixed with tenfold excess of staples in TE buffer (5 mM Tris and 1 mM EDTA) containing 10–20 mM MgCl2. The amount of MgCl2 varied with the structure: DN1 (10 mM), DN2 (6 mM), DN3 (10 mM), DN4 (10 mM), DN5 (10 mM), DN6 (12 mM), DN7 (14 mM), DN8 (12 mM) and DN9 (6 mM). The solutions were subjected to a thermal annealing ramp on a Tetrad 2 Peltier thermal cycler (Bio-Rad) according to the following schedule: incubate at 65 °C for 15 min, decrease to 50 °C, incubate at 50 °C for 6 h 30 min and decrease to 40 °C at 6 h 30 min °C−1. The quality of folding was analysed by AGE. Solutions of folded DN were concentrated tenfold using a 30k MWCO Amicon Ultra centrifugal filter device (Millipore) and then purified by glycerol gradient ultracentrifugation30 (link). The 45% and 15% glycerol solutions were made in 1 × TE buffer containing the same levels of MgCl2 as required for folding. The glycerol fractions containing nanostructures was concentrated and buffer exchanged to remove glycerol using a 30k MWCO Amicon Ultra centrifugal filter device. Following purification, the stock solution was diluted appropriately for TEM imaging to verify quality. The stock concentration was determined by ultraviolet absorbance at 260 nm on a Nanodrop spectrophotometer (Thermo Scientific), assuming that A260=1 for 50 μg ml−1 DNs. Stock solutions were stored at 4 °C until use.

Bacterial protein expression plasmids were transformed into E. coli Rosetta2 strain (Novagen, Gibbstown, NJ) and the protein was expressed in ZY autoinduction media. E. coli were grown to 0.6–0.8 of OD600 at 37°C 150rpm, then switched to 19°C for 16–20h shaking. Afterwards, bacteria were pelleted down at 5000g for 15min at 4°C, resuspended in lysis buffer (500mM NaCl, 50mM Tris, 5% glycerol, 1mM DTT, complete Protease Inhibitor Cocktail, pH 8.0). The resuspended bacteria were frozen by liquid nitrogen and then thawed. The thawed lysates were sonicated and centrifuged at 21,000g for 45mins at 4°C. The supernatant was filtered through 0.45μm filters and incubated with Sepharose 4B beads (Cytiva, Marlborough, MA) overnight at 4°C. GST-tagged proteins were eluted from Sepharose beads by incubating with L-reduced glutathione (20mM, pH 8.0) and exchanged to cleavage buffer (50mM Tris, 150mM NaCl, 1mM DTT, 1mM EDTA, pH 7.2) using a Vivaspin column (Cytiva, Marlborough, MA). The cleavage of GST was performed by PreScission Protease (Cytiva, Marlborough, MA) overnight at 4°C. The cleaved PNMA2 protein was run through a HiLoad 16/600 Superdex 200 pg (Cytiva, Marlborough, MA) size-exclusion column in the capsid assembly buffer (500mM phosphate, 50mM Tris, 0.5mM EDTA, pH 7.5) to further purify PNMA2 and facilitate capsid formation. For protein purified for mice immunization, Triton X-114 was used to wash GST-tagged protein bound to Sepharose beads to remove endotoxin.
