    Dual function of the PI3K-Akt-mTORC1 axis in myelination of the peripheral nervous system

    Gianluca Figlia, Camilla Norrmén ... Ueli Suter
    High PI3K-Akt-mTORC1 activity inhibits Schwann cell differentiation, while after onset of myelination, residual PI3K-Akt-mTORC1 activity promotes myelin growth.

    Regulation of human mTOR complexes by DEPTOR

    Matthias Wälchli, Karolin Berneiser ... Timm Maier
    Structural and functional analysis reveals the mechanistic basis for mammalian target of rapamycin (mTOR)-dependent roles of DEP domain-containing mTOR interacting protein (DEPTOR) in cancer and metabolic regulation.

    A critical role for mTORC1 in erythropoiesis and anemia

    Zachary A Knight, Sarah F Schmidt ... Jeffrey M Friedman
    Transcription profiling of activated cells using Phospho-Trap, a new method for identifying activated cells, reveals a critical role for mTOR signaling in red blood cell development and the pathogenesis of anemia

    The mTORC1-mediated activation of ATF4 promotes protein and glutathione synthesis downstream of growth signals

    Margaret E Torrence, Michael R MacArthur ... Brendan D Manning
    ATF4 is a metabolic effector of mTORC1 signaling, co-opted to induce gene targets involved in amino acid synthesis, uptake, and tRNA charging, contributing to mTORC1-driven protein and glutathione synthesis.

    Bipartite binding and partial inhibition links DEPTOR and mTOR in a mutually antagonistic embrace

    Maren Heimhalt, Alex Berndt ... Roger L Williams
    The inhibitory protein DEPTOR make two widely separated interactions with mTOR that are both necessary for its unique partial mTOR inhibition, and DEPTOR is a more potent inhibitor of mutation- or RHEB-activated mTORC1 than basal mTORC1.

    LARP1 functions as a molecular switch for mTORC1-mediated translation of an essential class of mRNAs

    Sungki Hong, Mallory A Freeberg ... Ken Inoki
    LARP1 turns off and on the translation of an essential class of mRNAs by acting as a key effecter and regulator for mTORC1.

    High mTOR activity is a hallmark of reactive natural killer cells and amplifies early signaling through activating receptors

    Antoine Marçais, Marie Marotel ... Thierry Walzer
    Chronic engagement of Natural killer cell inhibitory receptors by MHC-I molecules maintains a high activity of the mTOR pathway allowing subsequent amplification of signaling through activating receptors upon acute stimulation.

    Hyperactivity of mTORC1- and mTORC2-dependent signaling mediates epilepsy downstream of somatic PTEN loss

    Erin R Cullen, Mona Safari ... Matthew C Weston
    Epilepsy caused by focal Pten deletion is only prevented when both mTOR complexes are simultaneously inhibited, but not alone, suggesting they play independent roles in the development of epilepsy.

    Genetic inactivation of mTORC1 or mTORC2 in neurons reveals distinct functions in glutamatergic synaptic transmission

    Matthew P McCabe, Erin R Cullen ... Matthew C Weston
    The crucial regulator of brain function, mTOR, signals through distinct macromolecular complexes to control how synaptic vesicles are released from the presynaptic terminal.
