How do troponin and tropomyosin work together?

Troponin and tropomyosin work together as part of the thin filament of muscle cells. Tropomyosin is a rod-like protein that is wrapped around actin filaments, and it blocks the myosin binding sites on the actin. Troponin is a small protein that binds to the tropomyosin and changes its shape, allowing the myosin binding sites to be exposed so that contraction can occur. This occurs when calcium is released in response to a muscle signal.
