WebThin Filaments. Thin filaments are a polymer of actin with tightly bound regulatory proteins troponin and tropomyosin ( Fig. 39.4 ). When the cytoplasmic Ca 2+ concentration is low, troponin and tropomyosin inhibit the actin-activated adenosine triphosphatase (ATPase) of myosin. Tropomyosin, a 40-nm long coiled-coil of two α-helical ... WebEach protein in your cells consists of one or more polypeptide chains.
