Ras proteins in budding yeasts initially appeared to regulate initiation of the cell cycle in response to nutrient availability. More recent work, while clarifying the mechanisms of Ras-mediated signal transduction, bas undermined our notion of the signal Ras transmits. We now suspect that Ras helps to coordinate cellular metabolism and mass accumulation, but what Ras responds to is not clear.
