mTORC1 (mammalian target of rampamycin complex 1) is a highly conserved protein complex regulating cell growth and metabolism via its kinase mTOR (mammalian target of rapamycin). The activity of mTOR is under the control of various GTPases, of which Rheb and the Rags play a central role. The presence of amino acids is a strict requirement for mTORC1 activity. The heterodimeric Rag GTPases localize mTORC1 to lysosomes by their amino-acid-dependent interaction with the lysosomal Ragulator complex… Expand
PtdIns3P controls mTORC1 signaling through lysosomal positioning
TLDR
It is concluded that PtdIns3P-dependent lysosome translocation to the cell periphery promotes mTORC1 activation. Expand
Amino Acid-Dependent mTORC1 Regulation by the Lysosomal Membrane Protein SLC38A9
TLDR
The findings of this study reveal SLC38A9 as a Rag-Ragulator complex member transducing amino acid availability to mTORC1 activity, and during amino acid starvation mTOR is retained at the lysosome upon SLC 38A9 depletion but fails to be activated. Expand
Signal integration in the (m)TORC1 growth pathway
TLDR
The current level of molecular understanding of the upstream components of the (m)TORC1 signalling pathway, recent progress on this key biochemical frontier, and the future studies necessary to establish a mechanistic understanding of this master-switch for eukaryotic cell growth are discussed.

HSP70 interacts with Rheb, inhibiting mTORC1 signaling.
  • Hyang-Hwa Ryu, S. Ha

TLDR
The findings suggest that HSP70 is a negative regulator of mTORC1 signaling via interaction with Rheb, and this degradation is proteasome-dependent. Expand
mTORC1 Signaling-Activated Increases in Muscle Protein Synthesis induced by leucine and Phosphatidic Acid: A Brief Review
The mammalian target of rapamycin (mTOR) is a signaling network that functions to regulate muscle protein synthesis (MPS). The effects of leucine and phosphatidic acid (PA) availability and growthExpand
p27 regulates the autophagy-lysosomal pathway via the control of Ragulator and mTOR activity in amino acid deprived cells
TLDR
It is reported that in amino acid deprived cells, p27 controls autophagy via an mTORC1-dependent mechanism, and a direct, coordinated regulation between the cell cycle and cell growth machineries is revealed. Expand
The Rheb-TORC1 signaling axis functions as a developmental checkpoint
TLDR
RHEB-1 and DAF-15/Raptor, components of the nematode TORC1 complex, are necessary for animals to progress through each stage of post-embryonic development. Expand
Evolving Perspectives of mTOR Complexes in Immunity and Transplantation
  • D. Fantus, A. Thomson
  • Biology, Medicine
  • American journal of transplantation : official journal of the American Society of Transplantation and the American Society of Transplant Surgeons
  • 2015
TLDR
Recent advances in understanding and evolving perspectives of the role of mTOR complexes and mTOR targeting in immunity, with extrapolation to transplantation are addressed. Expand
Recent progress in the study of the Rheb family GTPases.
TLDR
Rheb's role in activating mTORC1 signaling at the lysosome in response to stimuli has been further elucidated and Rheb has also been suggested to play roles in other cellular pathways including mitophagy and peroxisomal ROS response. Expand
A VPS33A-binding motif on syntaxin 17 controls autophagy completion in mammalian cells
TLDR
It is found that the Stx17 N-peptide appears to interact in a positionally conserved, but mechanistically divergent manner with VPS33A, providing a late "go, no-go" step for autophagic fusion via a phosphoserine master-switch. Expand

Ragulator-Rag Complex Targets mTORC1 to the Lysosomal Surface and Is Necessary for Its Activation by Amino Acids
TLDR
It is shown that amino acids induce the movement of m TORC1 to lysosomal membranes, where the Rag proteins reside, and Rag-Ragulator-mediated translocation of mTORC1 is the key event in amino acid signaling to mtorC1. Expand
The Rag GTPases Bind Raptor and Mediate Amino Acid Signaling to mTORC1
TLDR
It is found that the Rag proteins—a family of four related small guanosine triphosphatases (GTPases)—interact with mTORC1 in an amino acid–sensitive manner and are necessary for the activation of the m TORC1 pathway by amino acids. Expand
Proton-Assisted Amino Acid Transporter PAT1 Complexes with Rag GTPases and Activates TORC1 on Late Endosomal and Lysosomal Membranes
TLDR
It is demonstrated in Human Embryonic Kidney cells that PAT1 is primarily located on LELs, physically interacts with the Rag GTPases and is required for normal AA-dependent mTOR relocalisation, and a model in which PATs function as part of an AA-sensing engine that drives mTORC1 activation from LEL compartments is proposed. Expand
Ragulator Is a GEF for the Rag GTPases that Signal Amino Acid Levels to mTORC1
TLDR
Mechanistic insight is provided into how mTORC1 senses amino acids by identifying Ragulator as a guanine nucleotide exchange factor (GEF) for the Rag GTPases. Expand
Phospholipase D Mediates Nutrient Input to Mammalian Target of Rapamycin Complex 1 (mTORC1)*
TLDR
It is reported here that elevated PLD activity in human cancer cells is dependent on both amino acids and glucose and that amino acid- and glucose-induced increases in mTORC1 activity are dependent on PLD. Expand

TLDR
The findings reveal an unexpected interaction between two cascades in the mTOR signaling pathways and open up additional possibilities for targeting this important growth-regulating network for the development of anticancer drugs. Expand
Rheb Binds and Regulates the mTOR Kinase
TLDR
This work shows that Rheb binds to the TOR complex specifically, independently of its ability to bind TSC2, through separate interactions with the mTOR catalytic domain and with LST8, whose binding enables activation of the TOR kinase. Expand
Novel role of the small GTPase Rheb: its implication in endocytic pathway independent of the activation of mammalian target of rapamycin.
TLDR
It is identified that Rheb expression in cultured cells induces the formation of large cytoplasmic vacuoles, which are characterized as late endocytic (late endosomes- and lysosome-like) components, which suggest that R heb regulates endocytics trafficking pathway independent of the previously identified mTOR pathway. Expand
Rheb Binding to Mammalian Target of Rapamycin (mTOR) Is Regulated by Amino Acid Sufficiency*
TLDR
The binding of Rheb to endogenous and recombinant mTOR is reversibly inhibited by withdrawal of all extracellular amino acids or just leucine, and the binding of mTOR to RheB mutants that are unable to bind guanyl nucleotide in vivo is also inhibited by amino withdrawal. Expand
Specific Activation of mTORC1 by Rheb G-protein in Vitro Involves Enhanced Recruitment of Its Substrate Protein*
TLDR
It is suggested that Rheb induces alteration in the binding of 4E-BP1 with m TORC1 to regulate mTORC1 activation, and does not induce autophosphorylation of mTOR. Expand
