Figure 10. Schematic of RNG2 location within the apical complex.
(A) Inferred positions of the N and C termini of RNG2 (labeled N-RNG2 and RNG2-C, respectively), conoid marker CAM1, and apical polar ring marker RNG1 within the structures of the apical complex, and with the conoid either retracted (subpellicular microtubules removed) or extruded. (B) Spatial model of RNG2 (orange and yellow), based on locations of protein termini, forming a collar between the apical polar ring and conoid. The collar is inverted upon conoid extrusion, potentially turning inside-out. See Figure 1 for full labeling of structures.
