title: Mum, this bud's for you: where do you want it? Roles for Cdc42 in controlling bud site selection in Saccharomyces cerevisiae.
abstract: The generation of asymmetric cell shapes is a recurring theme in biology. In budding yeast, one form of cell asymmetry occurs for division and is generated by anisotropic growth of the mother cell to form a daughter cell bud. Previous genetic studies uncovered key roles for the small GTPase Cdc42 in organizing the actin cytoskeleton and vesicle delivery to the site of bud growth, but a recent paper has also raised questions about how control of Cdc42 activity is integrated into a proposed hierarchical regulatory pathway that specifies a unique site of bud formation.
