Abstract

Fission yeast has two TOR kinases, Tor1 and Tor2. Recent studies have indicated that this microbe has a TSC/Rheb/TOR pathway like higher eukaryotes. Two TOR complexes, namely TORC1 and TORC2, have been identified in this yeast, as in budding yeast and mammals. Fission yeast TORC1, which contains Tor2, and TORC2, which contains Tor1, apparently have opposite functions with regard to the promotion of G1 arrest and sexual development. Rapamycin does not inhibit growth of wild-type fission yeast cells, unlike other eukaryotic cells, but precise analyses have revealed that rapamycin affects certain cellular functions involving TOR in this yeast. It appears that fission yeast has a potential to be an ideal model system to investigate the TOR signaling pathways.
