Opposite Effects of Tor1 and Tor2 on Nitrogen Starvation Responses in Fission Yeast

Abstract excerpt

The TOR protein kinases exhibit a conserved role in regulating cellular growth and proliferation. In the fission yeast two TOR homologs are present. tor1(+) is required for starvation and stress responses, while tor2(+) is essential. We report here that Tor2 depleted cells show a phenotype very similar to that of wild-type cells starved for nitrogen, including arrest at the G(1) phase of the cell cycle, induction...
