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.

Abstract

ShowHide

The mTORC1 kinase promotes growth in response to growth factors, energy levels, and amino acids, and its activity is often deregulated in disease. The Rag GTPases interact with mTORC1 and are proposed to activate it in response to amino acids by promoting mTORC1 translocation to a membrane-bound compartment that contains the mTORC1 activator, Rheb. We show that amino acids induce the movement of mTORC1 to lysosomal membranes, where the Rag proteins reside.

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.
