Myosin is responsible for actin-based muscular mobility/contraction.

Myosin makes up the THICK filaments, and actin makes up the thin filaments of myofibrils.
Actin and myosin
The thick protein filaments in a cell are primarily made of a protein called myosin. Myosin filaments are involved in muscle contraction and various other cellular processes such as cell motility and cytokinesis.
Titin functions as a structural protein in muscle cells, providing elasticity and stability to sarcomeres. Nebulin helps regulate the length of actin filaments in muscle cells, playing a role in muscle contraction and relaxation.
Motor proteins are responsible for the movement of muscle fibers in all three types of muscle tissue - skeletal, cardiac, and smooth muscles. These motor proteins interact with actin and myosin filaments to generate force and cause muscle contraction. In skeletal muscle, these motor proteins are predominantly myosin, while in cardiac and smooth muscles, they mainly consist of myosin and actin as well.

Myosin
The release of ADP and P from the myosin heads causes the myosin heads to change shape.
ATP (adenosine triphosphate) is the main substance that causes the myosin head to change shape during muscle contraction. When ATP binds to the myosin head, it energizes the myosin molecule and allows it to detach from actin, resetting the myosin head for the next contraction cycle.
