Ragulator-Rag complex targets mTORC1 to the lysosomal surface and is necessary for its activation by amino acids
What this study shows
Established WHERE mTORC1 gets switched on: the lysosome surface. Identified Ragulator as the lysosomal dock that recruits the Rag GTPases and drags mTORC1 to the membrane where its activator Rheb lives. Amino acids work by controlling this translocation.
At a glance
| Evidence type | M Molecular — cells, biochemistry, structure Marked M because it is molecular or in-vitro work (model: Human cells + Drosophila) rather than a whole-organism health-outcome study. That is often exactly where causal biology gets established -- the code says which system the finding was shown in, and nothing about how good the work is. |
