Abstract

How cells keep going in the face of adversity When cells experience stresses that affect their ability to process newly synthesized proteins, they turn down their rates of translation to help them survive the stress. They also turn on the translation of proteins that will help them cope with the misfolded proteins generated during stress. How do they turn down translation in general, but maintain or increase translation of specific proteins? Starck et al. developed an approach that allowed them to look at the translation of specific messenger RNAs that were not down-regulated by stress. They identified a motif that helped keep chaperone protein synthesis going. Science , this issue p. 10.1126/science.aad3867
