Data are presented as mean ± SEM. *P≤0.05, **P≤0.01, ^#P≤0.0001 Significantly different from F-Act88F^WT+Tpm. Significant differences between filament types ± Tpm at each myosin concentration were assessed using a two-way ANOVA with Bonferroni post-tests. Source data are provided as a Source Data file.
