Myosin II is found in the myofibers of skeletal, smooth, and cardiac muscle tissue where the protein forms the thick filaments. The myosin of the thick filaments has the ability to bind the thin filaments, composed of actin. The myosin head then rotates and pulls the two filaments past one another providing the basis for muscle contraction. | Myosin II is found in the myofibers of skeletal, smooth, and cardiac muscle tissue where the protein forms the thick filaments.

Myosin contains many polar side chains on the surface of the protein, but there are also a large number of nonpolar molecules on the surface. The following <scene name='Sandbox10/Hydrophobic/1'>scene</scene> shows a contrast between hydrophobic (gray) and hydrophilic molecules on the surface of the protein. | |||
