Analysis of a mitotic role of Cdc42

Abstract:
Rho GTPases including Rho, Rac, and Cdc42 determine the cell shape by regulating the actin and microtubule dynamics. Through these actions on cytoskeleton, Rho GTPases also regulate cell cycle progression. Specifically, Rho, Rac, and Cdc42 regulate G1-S progression, and Rho regulates cytokinesis. However, involvement of these GTPases in nuclear division has not been definitely shown. This seems to be due to the lack of standard procedures examining mitosis-specific functions of these GTPases. Recently, we have found a mitosis-specific role of Cdc42 by enrichment of cells in mitosis by cell cycle synchronization and interfering with functions of Rho GTPases. This chapter describes the procedures we used in these studies.

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
