Biochem/physiol Actions


Tropomyosin together with troponin, regulates the binding of myosin to actin. Tropomyosin is a dimeric coiled-coil protein forming continuous polymers along the myosin-binding groove of actin. Various tropomyosin isoforms help confer structure and function to actins in the cytoskeleton and striated muscle function. Dimeric protein that assumes an α-helical coiled-coil conformation. In the absence of Ca2+, it inhibits muscle contractility by blocking the myosin binding sites on actin.
