Recent studies on cultured neurons have demonstrated that microtubules are transported down the axon in the form of short polymers. The transport of these microtubules is bidirectional, intermittent, asynchronous, and occurs at the fast rate of known motors. The majority of the microtubule mass in the axon exists in the form of longer immobile microtubules. We have proposed a model called 'cut and run', in which the longer microtubules are mobilized by enzymes that sever them into shorter mobile polymers. In this view, the molecular motors that transport microtubules are not selective for short microtubules but rather impinge upon microtubules irrespective of their length. In the case of the longer microtubules, these motor-driven forces do not transport the microtubules in a rapid and concerted fashion but presumably affect them nonetheless. Here, we discuss the mechanisms by which the short microtubules are transported and suggest possibilities for how analogous mechanisms may align and organize the longer microtubules and functionally integrate them with each other and with the actin cytoskeleton.
