Structure of INF2-FFC and F-actin complexes. AFM image of INF2-FFC and F-actin complexes (at a 1:1 molar ratio) revealing ringlike binding around actin filaments. (a) Close-up of the INF2-FFC–F-actin complex displaying detailed orientations of adjacent INF2-FFC homodimer rings assembled around F-actin. Notably, there is 5–10° occasional bending of adjacent units, indicating flexibility or strain across the bound complex. (b) 3D side view (500×, 500 nm) showing the stacklike arrangement of INF2-FFC over F-actin. (c) Tubular structure spacing shown schematically.
