Some myosins are involved in musclecontraction. These myosins interact with other myosin proteins, forming thick filaments. In muscle cells, thick filaments

Calcium ion released from Troponin, covers binding site New calcium ion approaches next Troponin molecule How myosin interacts with actin to generate force is a subject of considerable controversy. The major debate centers on understanding at what point in force generation the inorganic phosphate is released with respect to the lever arm swing, or powerstroke. Resolving the controversy is essential for understanding how force is produced as well as the mechanisms underlying disease-causing Actin takes part in the regulation of chromatin structure, interacting with RNA polymerase I, II and III. In Pol I transcription, actin and myosin (MYO1C, which binds DNA) act as a molecular motor. For Pol II transcription, β-actin is needed for the formation of the preinitiation complex.

The key difference between actin and myosin is that actin exists as thin, short filaments while myosin exists as thick, long filaments in myofibrils of the muscle fibers. Actin-myosin contractile system is the main contractile system of all muscular tissues, and it works based on the interactions between the two proteins – the actin and myosin.
The myosin head now binds to the actin myofilament. Energy in the head of the myosin myofilament moves the head, which slides the actin past; hence ADP is released. ATP presents itself (as the presence of the calcium ions activates the myosin's ATPase), and the myosin heads disconnect from the actin to grab the ATP.
