title: Cell polarity: connecting to the cortex.
abstract: A GTPase module controls growth-site selection in budding yeast cells. The GDP--GTP exchange factor of this module, Bud5, has now been localized to sites of cell division and shown to interact with a transmembrane protein that marks these sites.
