The Neck Region of the Myosin Motor Domain Acts as a Lever Arm to Generate Movement

The myosin head consists of a globular catalytic domain that binds actin and hydrolyzes ATP and a neck domain that consists of essential and regulatory light chains bound to a long α -helical portion of the heavy chain. The swinging neck-lever model assumes that a swinging motion of the neck relativ...
