Webnumber of models to explain kinesin motion have since been entertained, which predict that the 8-nm step should be com-posed of substeps of one form or another. Substeps are by no means unreasonable to contemplate, for a variety of plausible reasons (see below). Two studies have claimed to identify substeps within the kinesin cycle.

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. …
