A family of contractile proteins, present in striated muscle and most eukaryotic cells that combines with actin to form actomyosin, and which in striated muscle gives the A-bands their dark color. This is myosin II (a two-headed, tailed variety). Myosin I (a single-headed, tailless variety) is involved in cell locomotion. Myosin moves actin filaments by virtue of ATP-fuelled structural changes. <\/p>\n
