kinesin

Kinesins are a class of motor proteins found in cells. They are dimers (molecule pairs) reminiscent of feet on a rod. Kinesins move on the much larger microtubule cables powerered by the hydrolysis of ATP. They achieve this probably by sequentially swinging their head domains ("feet/hands") to the front (see below). The active movement of kinesins pulls attached cargo through the viscous cytoplasm to deliver it to the required location.
