Binding and incorporation of ATM-3507 into Tpm3.1/actin filaments. (a) Increasing amounts of 3H-ATM-3507 (0–22 µM) pre-incubated with Tpm3.1 do not affect formation of Tpm-actin filament. Protein fractions of the Tpm-actin from both pellets and supernatants after centrifugation of the Tpm-actin mixture with increasing concentrations of ATM-3507. Full-length gels are presented in Supplementary Fig. 1. (b) The molar ratio of ATM-3507 to the junction formed by the N-terminal and C-terminal ends of Tpm dimers as a function of ATM-3507 concentration; n = 3. (c) Incorporation of 3H-ATM-3507 into Tpm/actin filament under two different conditions of (i) pre-incubated (Pre, black squares) 3H-ATM-3507 with 5 μM Tpm3.1 prior to actin addition, or (ii) post-incubated (Post, gray circles) 3H-ATM-3507 with the Tpm3.1/F-actin filaments; n = 4 for each curve.
