WebFeb 26, 2007 · The subsequent discovery of “limping” in kinesin, where the average kinetics of every other step switch between a faster and a slower stepping phase, proved that kinesin dimers advance through an asymmetric HoH motion, and that this motion is inconsistent with either the inchworm or symmetric HoH patterns.

WebMay 1, 2005 · Kinesin is a molecular walking machine that organizes cells by hauling packets of components directionally along microtubules. The physical mechanism that impels directional stepping is uncertain. WebKinesin-5 motor consists of two pairs of heads and tail domains, which are situated at the opposite ends of a common stalk. The two pairs of heads can bind to two antiparallel microtubules (MTs) and move on the two MTs independently towards the plus ends, sliding apart the two MTs, which is responsible for chromosome segregation during mitosis. …

WebApr 18, 2024 · Kinesin-1 is an ATP-driven, two-headed motor protein that transports intracellular cargoes (loads) along microtubules. The movement of kinesin-1 has generally been modeled according to its correlation with ATP cleavage (forward movement), synthesis (backward movement), or unproductive cleavage (futile consumption).
