چکیده

We present experimental and theoretical studies of the dynamics of molecular motors in microtubule arrays and asters. By solving a convection-diffusion equation we find that the density profile of motors in a two-dimensional aster is characterized by continuously varying exponents. Simulations are used to verify the assumptions of the continuum model. We observe the concentration profiles of kinesin moving in quasi-two-dimensional artificial asters by fluorescent microscopy and compare with our theoretical results.

Dynamic stability of spindles controlled by molecular motor kinetics

We analyze the role of the force-dependent kinetics of motor proteins in the stability of antiparallel arrays of polar filaments, such as those in the mitotic spindle. We determine the possible stable structures and show that there exists an instability associated to the collective behavior of motors that leads to the collapse of the structure. The agreement of our results and several experimen...

S. pombe Kinesins-8 Promote Both Nucleation and Catastrophe of Microtubules

The kinesins-8 were originally thought to be microtubule depolymerases, but are now emerging as more versatile catalysts of microtubule dynamics. We show here that S. pombe Klp5-436 and Klp6-440 are non-processive plus-end-directed motors whose in vitro velocities on S. pombe microtubules at 7 and 23 nm s(-1) are too slow to keep pace with the growing tips of dynamic interphase microtubules in ...

Microtubule motors in eukaryotic spindle assembly and maintenance.

The spindle is a microtubule-based structure that facilitates chromosome segregation during mitosis and meiosis. Spindle assembly from dynamic microtubule building blocks is a major challenge for the dividing cell and a process that critically requires microtubule motors. In this review we focus on the mechanisms by which microtubule motors shape the spindle. Specifically, we address how motors...

Single Molecule Imaging Reveals Differences in Microtubule Track Selection Between Kinesin Motors

Cells generate diverse microtubule populations by polymerization of a common alpha/beta-tubulin building block. How microtubule associated proteins translate microtubule heterogeneity into specific cellular functions is not clear. We evaluated the ability of kinesin motors involved in vesicle transport to read microtubule heterogeneity by using single molecule imaging in live cells. We show tha...

Poleward transport of Eg5 by dynein–dynactin in Xenopus laevis egg extract spindles

Molecular motors are required for spindle assembly and maintenance during cell division. How motors move and interact inside spindles is unknown. Using photoactivation and photobleaching, we measure mitotic motor movement inside a dynamic spindle. We find that dynein-dynactin transports the essential motor Eg5 toward the spindle poles in Xenopus laevis egg extract spindles, revealing a direct i...
