Rhb1 (a fission yeast homolog of Rheb) regulates amino acid uptake as well as response to nitrogen starvation. In this study, we generated two mutants, rhb1-DA4 and rhb1-DA8, and characterized them genetically. The V17A mutation within the G1 box defined for the Ras-like GTPases was responsible for rhb1-DA4 and Q52R I76F within the switch II domain for rhb1-DA8. In fission yeast, two events--the induction of the meiosis-initiating gene mei2+ and cell division without cell growth--are a typical response to nitrogen starvation. Under nitrogen-rich conditions, Rheb stimulates Tor kinase, which, in turn, suppresses the response to nitrogen starvation. While amino acid uptake was prevented by both rhb1-DA4 and rhb1-DA8 in a dominant fashion, the response to nitrogen starvation was prevented only by rhb1-DA4. rhb1-DA8 thereby allowed genetic dissection of the Rheb-dependent signaling cascade. We postulate that the signaling cascade may branch below Rhb1 or Tor2 and regulate the amino acid uptake and response to nitrogen starvation independently."xsd:string |
