Abstract

Proper spatial and temporal regulation of the small GTPase RhoA at the equatorial cortex represents a critical step in the specification of the division plane in eukaryotes. Despite increased understanding of the mechanisms whereby RhoA becomes active following chromosome segregation, far less is known about how RhoA is spatially regulated so that it concentrates precisely at the division site. In the April 1, 2009, issue of Genes & Development, Yoshida and colleagues (pp. 810-823) uncovered two genetically separable mechanisms whereby Rho1 is recruited to the bud neck in the budding yeast Saccharomyces cerevisiae to facilitate cytokinesis.
