The Nature and Significance of ATP-Induced Contraction of Microtubule Gels
Among the most essential, and dramatic, events in the life of a cell are the processes of cell motility. Cytoplasmic microtubules (we will not consider flagella and cilia microtubules in the present discussion) are a key element in cellular motility (for a review, see Hyams and Stebbings 1979). They appear to be involved in such diverse phenomena as chromosome movement during mitosis, transport of vesicles in axons (Allen et al. 1985) and other cells (Hayden et al. 1983), and elongation of retina cells (Warren and Burnside 1978). Although extensively investigated little is known about either the process controlling microtubule organization in cells, or about the mechanism by which they produce movement.
