Myosin is a superfamily of motor proteins that, together with actin proteins, form the basis for the contraction of muscle fibers. Myosin is termed a motor protein as it is a type of enzyme that converts chemical energy into mechanical energy. Myosins (/ ˈmaɪəsɪn, - oʊ -/) are a superfamily of motor proteins best known for their roles in muscle contraction and in a wide range of other motility processes in eukaryotes. They are ATP -dependent and responsible for actin -based motility. This myosin forms polar bonds with actin monomers, giving rise to a configuration that looks like arrows with feather fletchings along its shaft, where the shaft is the actin and the fletchings are the myosin. Myosin II is the motor protein of the sarcomeric thick filament that transduces the chemical energy of ATP hydrolysis and release of ADP and Pi into mechanical energy that drastically alters the conformation of the protein.

They control the voluntary muscular movements of the body in concert with the regulatory proteins known as tropomyosin, troponin, and meromyosin. Actin and myosin proteins form filaments arranged in the myofibrils in a longitudinal manner.

The motor proteins that transport materials along the acting microfilaments are similar in some ways, such as the globular head group that binds and hydrolyzes ATP, yet different in other ways, such as the motion catalyzed by the ATP hydrolysis. Actin filaments, usually in association with myosin, are responsible for many types of cell movements. Myosin is the prototype of a molecular motor—a protein that converts chemical energy in the form of ATP to mechanical energy, thus generating force and movement. 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.

Magnesium and ADP released from Myosin head ends contraction.
