Measurement of activity of rho GTPases during mitosis.
The members of Rho-family GTPases regulate progression through mitosis. Rho induces the contractile ring at the equatorial cortex of the dividing cell, and thus works as a molecular switch between nuclear division and cytokinesis. Cdc42 regulates the progression from prometaphase to metaphase by stabilizing microtubule attachment to the kinetochore. These results suggest that Rho GTPases are activated at specific points in mitosis and regulate each step. Here we describe the methods to analyze the activity and regulation of Rho GTPases during mitosis.
