Conformation of troponin core domain and tropomyosin positions. The high and low Ca²⁺ models 6KN8 (green) and 6KN7 (blue) were docked into our thin filament reconstruction and compared to our zebrafish model (yellow). A & B: the core domains of Tn1 and Tn2. Regions of empty density are indicated with *. B: ɑ (45°) & (35°) the angle the TnI helix 1 makes with the horizontal in the two states C & D: the tropomyosin overlap region where TnT1 domain is located of Tn1 and Tn2 respectively. E,F, & G: Pairwise comparison of the position of tropomyosin from the three models
