Research Abstract

We investigated the role of Drs/GADD34 in cell responses under various stress conditions by using gene knockout cells and found that Drs plays critical roles for the control of cell responses in energy deprivation, hypoxia, energy metabolism and viral infection. Drs binds to GADD34 to regulate mTOR pathway via TSC1/2 phosphorylation control
