WebSummary. Tropomyosin is a regulatory protein that plays its role in muscle contraction as well as intracellular transport of substances. It is found in muscle cells as a component of actin filaments as well as in the cytoskeleton of non-muscle cells. Its synthesis involves the transcription of tropomyosin genes and the translation of mRNA. WebTroponin is a central regulatory protein of striated muscle contraction, and together with tropomyosin, is located on the actin filament. Troponin consists of 3 subunits: TnI, which is the inhibitor of actomyosin ATPase; TnT, which contains the binding site for tropomyosin; and TnC, the protein encoded by this gene. The binding of calcium to TnC abolishes the … chevy tag plates

"WebLet's discuss each myofilament in turn. Each actin molecule is composed of two strands of fibrous actin (F-actin) and a series of troponin and tropomyosin molecules. Each F-actin is formed by two strings of globular actin (G-actin) wound together in a double helical structure, much like twisting two strands of pearls with each other.
