According to B. Alberts tropomyosin is an elongated protein, which stabilizes actin filaments by binding to seven adjacent actin subunits, thus preventing it from interacting with other proteins.[1] Tropomyosin, along with troponin play an important role in regulation of muscle contraction.[2] As tropomyosin binds to actin it follows its helical structure.[3] Fig.1
This figure describes the relative position of accesory proteins and actin in a thin filament. Troponin complex is bound to actin and tropomyosin, which lies in the groove of the actin helix.
