What is the fine-grained topic of the following text: When stress signals are gone, the kinase activity of DYRK3 is required for the dissolution of SGs and mTORC1 relocation to the cytosol, and for phosphorylating PRAS40, which attenuates the binding of PRAS40 to the mTORC1 complex. Only return the topic.
