TOR signalling

TOR (target of rapamycin) signalling is a cell signalling pathway. TOR and its mammalian ortholog mTOR are serine-threonine kinases that sense growth factor, nutrient or oxygen status and promote appropriate changes in cell growth and proliferation, cell survival, and protein synthesis. TOR signalling has key roles in cancer and autophagy.

    Nutrient availability and the cell cycle are known to affect chromatin accessibility. A fundamental question is which mechanisms are involved in connecting nutrient levels, the cell cycle and chromatin regulation. In this issue, Zhang et al. reveal a signalling cascade whereby nutrient-sensing mTORC1 activates the cell-cycle regulator CDK2, thus leading to nuclear translocation of the metabolic enzyme triosephosphate isomerase 1 (TPI1). In the nucleus, TPI1 alters the levels of acetate and global histone acetylation through the metabolite dihydroxyacetone phosphate.

    Maintaining plasma membrane tension is important for eukaryotic cells. How altered membrane tension is sensed and relayed to downstream factors, such as the target of rapamyin complex 2 (TORC2), is poorly understood. Reorganization of a signalling lipid into discrete membrane domains is now shown to inactivate TORC2 in yeast.
