| Research Abstract |
TOR protein kinase forms two different complexes, one of which is TOR complex 2 (TORC2) that phosphorylates and activates the oncogene product Akt. Akt is known to play key roles in cell proliferation of mammalian early development as well as that of cancerous cells. In addition, the TORC2-Akt pathway mediates insulin signaling to induce glucose uptake in muscle and fat cells. Because TORC2 is highly conserved between human and the fission yeast Schizosaccharomyces pombe, this study utilized fission yeast as a model system to examine the regulatory mechanisms of TORC2 activity. Our results strongly suggest that small GTPases are involved in activation of TORC2. In addition, candidates of novel TORC2 activators have been identified through genetic screens.
