Title	TFEB regulates protein synthesis to sustain autophagy during starvation
Description	In response to starvation, cells undergo a metabolic shift to ensure their survival by shutting down protein synthesis and activating catabolic processes, including autophagy, to degrade proteins and recycle nutrients. These processes, however, do require protein synthesis. We asked how this fundamental conflict is resolved. Upon starvation, cells activate the Integrated Stress Response (ISR) and inhibit mammalian target of rapamycin complex 1 (mTORC1). The ISR inhibits protein translation through the phosphorylation of the alpha subunit of eukaryotic translation initiation factor 2 (eIF2), whereas mTORC1 inhibition induces activation of the transcription factors TFEB/TFE3. We discovered that PPP1R15A (aka GADD34), a member of the protein phosphatase 1 complex (PP1) is a direct and early target of TFEB. GADD34 recruits PP1 to dephosphorylate eIF2 and thus fine-tunes protein synthesis to enable translation of the transcriptional program induced by starvation leading to a sustained autophagic flux.
