[[Troponin]] (Tn) is a regulatory protein in muscle contraction. It contains 3 subunits: TnC causes conformational change in TnI when it binds to calcium ions. TnT binds to [[Tropomyosin|tropomyosin]] and TnI binds to actin which is found in thin muscle filaments. The images at the left and at the right correspond to one representative Tn, ''i.e.'' the crystal structure of complex Troponin C/Troponin I/Troponin T ([[1yv0]]).
