Abstract

Limiting mTORC1: The mTORC1 protein kinase complex has important functions linking metabolism to cell growth and its functions are disrupted in common diseases, including cancer and diabetes. Bar-Peled et al. (p. 1100 ; see the Perspective by Shaw ) discovered regulatory components that help turn down signaling by mTORC1 when cells are deprived of amino acids. Two complexes of proteins, GATOR1 and GATOR2, have opposite effects on activity and cellular localization of mTORC1. Components of the GATOR1 complex negatively regulate mTORC1 and appear to function as tumor supressors. Cancers with loss of GATOR1 function may be particularly amenable to therapeutic strategies that limit activity of mTORC1.

  • CG12090 is the Drosophila ortholog of mammalian DEPDC5, which was found to be part of the GATOR1 complex that inhibits the Tor pathway.

    “These include CG12090, the Drosophila ortholog of mammalian DEPDC5, which was found to be part of the GATOR1 complex that inhibits the Tor pathway during the protracted course of our studies.”

    From Functional unknomics: Systematic screening of conserved genes of unknown function (2023) · cites this paper as [54]

    The paper identifies DEPDC5 as a GATOR1 component (passage 7, section labeled Abstract) and reports that loss of dDEPDC5 prevents normal inactivation of Drosophila TORC1 during amino acid deprivation (passage 1, same section). Our copy does not identify dDEPDC5 as CG12090, so it does not verify that specific gene-to-ortholog mapping. (LLM, conf=0.86)

  • WDR59 and WDR24 are both subunits of GATOR2 complex, which functions as a positive regulator of amino-acid-mediated mTORC1 activation.

    “WDR59 and WDR24 are both subunits of GATOR2 complex, which functions as a positive regulator of amino‐acid‐mediated mTORC1 activation (Bar‐Peled et al., 2013), and WDR24 modulates mTOR through the previously described changes in lysosome cellular positioning and dynamics (Korolchuk et al., 2011) and thus indirectly modulates autophagic flux (Cai et al., 2016).”
  • Mutants in GATOR1 subunits promote cell growth by increasing Tor activity.

    “Mutants in GATOR1 subunits promote cell growth by increasing Tor activity [54,55].”
  • At the Ragulator, the Rag heterodimer interacts with GATOR, an octomeric complex that controls the activity of the Rag proteins.

    “At the Ragulator, the Rag heterodimer interacts with GATOR (GAP Activity Towards Rags), an octomeric complex that controls the activity of the Rag proteins [22].”

    From Using Molecular Biology to Maximize Concurrent Training (2014) · cites this paper as [22]

  • Upstream regulation of the Rag GTPases features at least four large protein complexes: GATOR1, a GAP for RagA/RagB/Gtr1; FLCN-FNIP, a GAP for RagC/RagD/Gtr2; GATOR2, an inhibitor of GATOR1; and KICSTOR, which is thought to regulate the GATOR complexes.

    “Upstream regulation of the Rag GTPases is more baroque, featuring at least four large protein complexes including: GATOR1, a GAP for RagA/RagB/Gtr1 (Neklesa and Davis, 2009; Bar-Peled et al., 2013; Panchaud et al., 2013a); FLCN-FNIP (Lst4-Lst7 in yeast), a GAP for RagC/RagD/Gtr2 (Péli-Gulli et al., 2015; Petit et al., 2013; Tsun et al., 2013); GATOR2, an inhibitor of GATOR1 (Bar-Peled et al., 2013”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
