eIF2α integrates proteotoxic signals both from ER and cytoplasm: Hsp70-Bag3 module regulates HRI-dependent phosphorylation of eIF2α
S. Patel, S. Kumar, A. Hesin…·M. Y. Sherman
The paper shows that JG-98, an Hsp70 inhibitor, causes cell death by activating the eIF2α phosphorylation pathway through the Hsp70-Bag3 complex, linking ER and cytoplasmic proteotoxicity.
