How do cells determine whether to live or die after exposure to stressors that cause misfolding of intracellular proteins? Lin et al. find that the IRE1 signaling branch of the unfolded protein response plays a key role in promoting cell survival after protein misfolding in the endoplasmic reticulum (ER). Human cells shut off IRE1 signaling after prolonged ER protein misfolding in order to enhance cell survival.
