Interaction analysis among actin, myosin, and tropomy-osin were performed at 298 K (degree kelvin) with a MicroCal Isothermal Titration Calorimeter ITC200 in-strument (Malvern, England). The investigations were performed according to a strictly standardized protocol [7–9].

Muscle contraction is resulted from the interaction of myosin with actin and ATP. The study of kinetics of binding of myosin subfragment 1 (S1) to F-actin revealed the two step binding, which were

Actin–myosin interaction and force The Cytoskeletal Network of the Trabecular Meshwork*. B. Tian, B. Geiger, in Encyclopedia of the Eye, 2010 Inherited Cardiomyopathies. Polakit The actin–myosin interaction produces two types of movements: force generation between actin filaments leading to contractions, such as in muscle contraction, cell motility, and cytokinesis; and transport of subcellular organelles and macromolecular complexes by myosin motors along actin filaments. The binding of myosin to actin can be weak or strong. The affinity, which changes over 5 orders of magnitude, is controlled by ATP binding to the myosin head at a position remote from the actin binding site. ATP binding produces “weak binding.” In the absence of ATP the binding is “strong.” The free calcium ions will interfere with tropomyosin/troponin regulation of myosin/actin binding. This allows myosin to bind to actin.

Actin myosin interaction

Actin-myosin interactions play crucial roles in the generation of cellular force and movement. The molecular mechanism involves structural transitions at the interface between actin and myosin's catalytic domain, and within myosin's light chain domain, which contains binding sites for essential (ELC) and regulatory light chains (RLC).
