MAR20122012DPinned down the direct mTORC1-TFEB link: mTORC1 (docked at the lysosome via Ragulator) phosphorylates TFEB on Ser211, which traps it in the cytosol via 14-3-3 proteins. Inhibit mTORC1 and TFEB rushes
ZON20112011DShowed amino acid sensing starts INSIDE the lysosome: amino acids accumulate in the lumen and the v-ATPase relays that signal outward ('inside-out') to Ragulator-Rag. A surprising twist on where the c
