Yeast cells polarize, bud, and divide in either of two genetically programmed patterns: axial or bipolar. The Saccharomyces cerevisiae gene BUD1 (also known as RSR1) encodes a Ras-related GTPase critical for selection of a bud sites in these patterns. To distinguish between possible mechanisms of Bud1p action, we have examined the function and subcellular localization of Bud1p in a variety of mutant situations.
