Mechanisms of chromosome biorientation and bipolar spindle assembly analyzed by computational modeling

June 4, 2019

We develop a computational model of fission-yeast mitosis using a course-grained Brownian Dynamic framework in conjunction with a force-dependent kinetic Monte Carlo algorithm to replicate the biorientation and segregation of chromosomes.

Contributions of microtubule dynamic instability and rotational diffusion to kinetochore capture

June 24, 2016

Recent work has found that microtubule rotational diffusion about minus-end attachment points contributes to kinetochore capture in fission yeast, but the relative contributions of dynamic instability and rotational diffusion are not well understood.

Kinesin-8 effects on mitotic microtubule dynamics contribute to spindle function in fission yeast

April 28, 2016

To better understand the role of kinesin-8 proteins in mitosis, we have studied the effects of deletion of the fission-yeast kinesin-8 proteins Klp5 and Klp6 on chromosome movements and spindle length dynamics.

Regulation of chromosome speeds in mitosis

Sept. 6, 2013

When chromosomes are being separated in preparation for cell division, their motions are slow relative to the speed at which many motor enzymes can move their cellular cargoes and at which microtubules depolymerize.
