Fig. 4. Mechanical regulation of actin dynamics.

Fig. 4

(A) G-actin and F-actin form more pronounced catch-slip bonds (red) than that between two G-actins (green). (B) Catch bonds of G-actin–F-actin remain the same in the presence of actin end-binding proteins, Tmod3 (magenta) or CapZ (blue). (C) Hypothesized transition of G-actin–F-actin catch-slip bond (red) to pure slip bond (purple) in the presence of an actin end-binding protein.
