(Biochemistry) a complex protein in skeletal muscle that is formed by actin and myosin and which, when stimulated, shortens to cause muscle contraction


(ˌæk təˈmaɪ ə sɪn)

a complex of the proteins actin and myosin that is a major constituent of muscle tissue and that interacts with ATP to cause muscular contraction.
