Abstract excerpt

BACKGROUND: Rho family small GTPases have been shown to be involved in various cellular activities, including the organization of actin cytoskeleton in eukaryotic cells. There are six rho genes in the fission yeast Schizosaccharomyces pombe. Cdc42 is known to control the polarity of the cell. Rho1, Rho2 and Rho3 play important roles in controlling cell shape and septation. On the other hand, Rho4 and Rho5 have...
