Localization of the Rsr1/Bud1 GTPase involved in selection of a proper growth site in yeast.

The Journal of biological chemistry - 26 Jul 2002

Park Hay-Oak, Kang Pil Jung, Rachfal Amy Wilson

Abstract excerpt

Yeast cells organize their actin cytoskeleton in a highly polarized manner during vegetative growth. The Ras-like GTPase Rsr1/Bud1 and its regulators are required for selection of a specific site for growth. Here we showed that Rsr1/Bud1 was broadly distributed on the plasma membrane and highly concentrated at the incipient bud site and polarized growth sites. We also showed that localization of Cdc24, a guanine...
