Tropomyosin is a progression of long string-like polypeptides joined start to finish that matches every F actin strand, strengthens and solidifies the F dynamic strands, and capacities to either cover up or uncover the "dynamic sites" on each globular actin molecule.
One single tropomyosin atom is sufficiently long to cover the dynamic restricting destinations on seven G-actin particles.
These are where actin atoms tie with the thicker myosin particles.
