Description: EN6-mediated ATP6V1A modification decouples the v-ATPase from the Rags, leading to inhibition of mTORC1 signaling, increased lysosomal acidification and activation of autophagy. EN6 clears TDP-43 aggregates, a causative agent in frontotemporal dementia, in a lysosome-dependent manner. EN6 is a...

EN6 is an activator of autophagy. It inhibits mammalian target of rapamycin complex 1 (mTORC1) signaling by binding covalently to cysteine 277 of the ATP6V1A catalytic subunit of the lysosomal vacuolar ATPase (v-ATPase) and impairing v-ATPase coupling with Rag GTPases. It is selective for inhibition of mTORC1 over...
