Mtor encodes mechanistic target of rapamycin, a large PI3K-related serine/threonine protein kinase. mTOR is the catalytic subunit of mTORC1 and mTORC2 complexes, integrating nutrient, growth-factor, energy, and stress inputs to regulate proximal outputs including translation, cell growth, autophagy, and AKT/PKC-family kinase signaling. Because mTOR is highly pleiotropic, tissue phenotypes and distal metabolic or developmental consequences are treated as non-core unless they directly describe TORC kinase signaling.

The research report should be a detailed narrative explaining the function, biological processes, and localization of the gene product. Citations should be given for all claims.
You should prioritize authoritative reviews and primary scientific literature when conducting research. You can supplement
this with annotations you find in gene/protein databases, but these can be outdated or inaccurate.
We are specifically interested in the primary function of the gene - for enzymes, what reaction is catalyzed, and what is the substrate specificity? For transporters, what is the substrate? For structural proteins or adapters, what is the broader structural role? For signaling molecules, what is the role in the pathway.
We are interested in where in or outside the cell the gene product carries out its function.
We are also interested in the signaling or biochemical pathways in which the gene functions. We are less interested in broad pleiotropic effects, except where these elucidate the precise role.
Include evidence where possible. We are interested in both experimental evidence as well as inference from structure, evolution, or bioinformatic analysis. Precise studies should be prioritized over high-throughput, where available.
Mouse Mtor encodes mechanistic/mammalian target of rapamycin (mTOR), a PI3K-related serine/threonine kinase that nucleates two signaling complexes, mTORC1 and mTORC2, which coordinate growth-factor, nutrient, and energy-stress information to regulate translation, metabolism, autophagy, and cytoskeletal programs. The most current mechanistic model places mTORC1 activation on the cytosolic face of lysosomal membranes, where Rag–Ragulator (nutrient/amino-acid arm) and Rheb (growth-factor arm downstream of TSC1/2) converge to recruit and catalytically activate mTORC1. Recent (2024) cryo-EM reconstitution studies quantify this synergy and provide a structural rationale for signal integration at the lysosome. Translationally, partial pathway coverage by first-generation rapalogs has motivated development of ATP-competitive mTORC1/2 inhibitors and bi-steric mTORC1-selective inhibitors, with measurable (but toxicity-limited) clinical activity; in parallel, mTOR inhibition is now being implemented in aging/metabolism and even dermatologic trials.
Multiple 2024 reviews explicitly define mTOR as the “mammalian target of rapamycin” and describe it as a PI3K-related protein kinase, aligning with the UniProt entry for mouse Mtor (UniProt Q9JLN9). (marafie2024mtoritscritical pages 1-3, basnet2024mammaliantargetof pages 7-8)
mTOR is the catalytic kinase within:
- mTORC1: includes mTOR, Raptor, mLST8, and regulatory subunits such as PRAS40 and DEPTOR (with some reviews also listing assembly/stability factors like Tel2/Tti1). (marafie2024mtoritscritical pages 1-3, chen2024targetingthemtorautophagy pages 2-4)
- mTORC2: includes mTOR, Rictor, mSIN1, mLST8, and DEPTOR (some reviews also note Protor). (marafie2024mtoritscritical pages 1-3, basnet2024mammaliantargetof pages 2-4)
Canonical outputs:
- mTORC1 phosphorylates S6K1/2 and 4E-BP1/2 (translation/growth control). (marafie2024mtoritscritical pages 1-3, basnet2024mammaliantargetof pages 2-4, cui2024structuralbasisfor pages 23-28)
- mTORC2 promotes Akt Ser473 phosphorylation, supporting survival and other downstream programs. (marafie2024mtoritscritical pages 1-3, basnet2024mammaliantargetof pages 2-4, subbiah2024phaseistudy pages 1-2)
A widely used pathway abstraction is that growth-factor/PI3K signaling activates Akt, which inhibits TSC1/2, allowing Rheb to stimulate mTORC1. (marafie2024mtoritscritical pages 1-3, basnet2024mammaliantargetof pages 2-4)
A 2024 cryo-EM and biochemical reconstitution study (Cui et al., bioRxiv; publication date Nov 2024, https://doi.org/10.1101/2024.11.15.623810) reconstructed an mTORC1–Rheb–Rag–Ragulator–4EBP1 complex on membranes and quantified the synergy between nutrient and growth-factor arms:
- >35-fold activation of mTORC1 kinase activity with liposomes + Rag–Ragulator + Rheb-GTP (vs baseline), while Rheb-GTP alone on vesicles produced ~3-fold activation in the reported conditions. (cui2024structuralbasisfor pages 4-7)
- Physiologic reconstitution conditions in the excerpt include 250 nM Rheb and 300 nM RagA/C–Ragulator. (cui2024structuralbasisfor pages 4-7)
- Membrane geometry mattered: small 30–50 nm liposomes reduced activity by ~65%, indicating a potential role for membrane curvature/shape in mTORC1 activation efficiency. (cui2024structuralbasisfor pages 4-7)
- The authors propose a three-step proximity/engagement model: Rag–Ragulator recruitment brings mTORC1 within ~100 Å of the membrane; Rheb recruitment brings it within ~40 Å; then direct mTOR/Raptor membrane engagement completes maximal activation. (cui2024structuralbasisfor pages 4-7)
- Cell-based validation in Raptor KO MEFs quantified decreased pS6K and p4EBP1 after perturbations, reporting n=3 experiments and P < 0.0001 in a two-way ANOVA framework. (cui2024structuralbasisfor pages 23-28)
These results strengthen the current view that mTORC1 is activated at lysosomal membranes via coordinated, multi-component recruitment and membrane engagement. (cui2024structuralbasisfor pages 7-10, cui2024structuralbasisfor pages 23-28)
A 2023 study in Life Metabolism (publication date Mar 2023, https://doi.org/10.1093/lifemeta/load005) supports a hierarchical inhibition model in which glucose starvation triggers AXIN lysosomal translocation to inactivate/sunder mTORC1 from lysosomes via Rag inhibition, and AMPK further inhibits mTORC1 through phosphorylation of Raptor and TSC2, particularly under severe stress. (li2023hierarchicalinhibitionof pages 12-13)
Multiple sources converge on the lysosome as a key spatial node for mTORC1 regulation:
- Structural reconstitution directly places the activating complex on membranes with Ragulator and lipidated Rheb providing membrane anchoring and shows direct membrane-contacting features in mTOR and Raptor. (cui2024structuralbasisfor pages 7-10, cui2024structuralbasisfor pages 23-28)
- A 2024 review notes Raptor’s role in mTORC1 stability/substrate recognition and explicitly links it to localization to lysosomal surfaces. (chen2024targetingthemtorautophagy pages 2-4)
The gathered evidence set is strongest on lysosomal recruitment/activation; it does not exclude additional pools (e.g., cytoplasmic, other organelles). A recent conceptual advance (not fully quantified in the retrieved excerpts) is that different amino-acid sources may produce spatially separated mTORC1 signaling, implying non-lysosomal mTORC1 substrate phosphorylation can occur under some nutrient contexts. (fernandes2024spatialandfunctional, retrieved but not evidence-extracted here)
Amino-acid sensing is mediated through Rag GTPases and Ragulator, which recruit/organize mTORC1 on lysosomal membranes; this architecture is explicitly reconstituted structurally and biochemically in the 2024 membrane cryo-EM system. (cui2024structuralbasisfor pages 4-7, cui2024structuralbasisfor pages 23-28)
Akt-dependent inhibition of TSC1/2 is a standard mechanism for permitting Rheb activation of mTORC1, and structural work references TSC2 as the opposing GAP for Rheb. (marafie2024mtoritscritical pages 1-3, cui2024structuralbasisfor pages 23-28)
Glucose starvation and energetic stress inhibit mTORC1 through AXIN and AMPK, including Rag-dependent lysosomal mechanisms and AMPK phosphorylation of Raptor/TSC2. (li2023hierarchicalinhibitionof pages 12-13)
Therapeutic targeting has progressed from rapamycin/rapalogs to catalytic inhibitors because rapalogs can yield incomplete pathway suppression (notably limited 4E-BP1 effects) and allow compensatory signaling (including via mTORC2/Akt). (du2023bistericmtorc1inhibitors pages 1-2, subbiah2024phaseistudy pages 1-2, marafie2024mtoritscritical pages 8-9)
A key quantitative clinical example is a Phase I trial of dual mTORC1/2 inhibition:
- Sapanisertib (TAK-228/MLN0128) + metformin in 30 heavily pretreated patients showed 4/30 partial responses, 15/30 stable disease, and 63% disease control; Grade 3–5 treatment-related AEs included hyperglycemia 13% and fatigue 7%; MTD was 4 mg sapanisertib + 1,000 mg metformin (publication date Dec 2024, https://doi.org/10.1158/2767-9764.crc-22-0260). (subbiah2024phaseistudy pages 1-2)
Preclinical benchmarking and mechanistic translation:
- In a 2023 JCI study (publication date Nov 2023, https://doi.org/10.1172/jci167861), rapamycin had no effect on p-4EBP1 even at 100 nM, whereas MLN0128 reduced phospho-sites at 10–30 nM and inhibited p-AKT Ser473 at 100 nM; bi-steric mTORC1-selective inhibitors nearly abolished mTORC1 activity at 0.3 nM and increased apoptosis compared with rapamycin or MLN0128. (du2023bistericmtorc1inhibitors pages 1-2)
ClinicalTrials.gov records show ongoing implementation of mTOR modulation in aging/metabolism:
- NCT05835999 (Everolimus Aging Study): Phase 2, randomized, placebo-controlled trial (start 2023-03-24) testing everolimus 0.5 mg/day vs 5 mg/week vs placebo for 24 weeks in adults 55–80 with insulin resistance/prediabetes; primary endpoint is insulin sensitivity during a dual-tracer 75 g OGTT. URL: https://clinicaltrials.gov/study/NCT05835999. (NCT05835999 chunk 1)
- NCT06658093 (RESTOR): early-phase interventional PK/PD dose-optimization of sirolimus and everolimus in healthy older adults (estimated enrollment 194, start 2025-08-13, recruiting). URL: https://clinicaltrials.gov/study/NCT06658093. (NCT06658093 chunk 1)
Across 2024 reviews and 2023–2024 primary studies, a consistent expert-level interpretation emerges:
1. Spatial control is central: mTORC1’s lysosomal recruitment and membrane engagement are not incidental but mechanistically required for robust signal integration (nutrients + growth factors). (cui2024structuralbasisfor pages 7-10, cui2024structuralbasisfor pages 23-28)
2. Therapeutic depth vs tolerability trade-off: deeper blockade (catalytic inhibitors, dual mTORC1/2) can address rapalog escape but introduces toxicity constraints; hence renewed interest in mTORC1-selective but mechanistically complete inhibitors (e.g., bi-steric agents) to suppress 4E-BP1 while limiting mTORC2-associated liabilities. (du2023bistericmtorc1inhibitors pages 1-2, subbiah2024phaseistudy pages 1-2)
The following artifacts and evidence figure crops summarize key mechanistic aspects:
| Aspect | Current understanding (concise) | Key evidence (include paper title, year, and DOI URL) | Notes/limitations |
|---|---|---|---|
| Verified identity | Mouse Mtor (UniProt Q9JLN9) corresponds to mechanistic/mammalian target of rapamycin (mTOR), a PI3K-related serine/threonine protein kinase. The retrieved literature aligns with the UniProt description and known synonyms “mammalian target of rapamycin” and “mTOR”. (marafie2024mtoritscritical pages 1-3, basnet2024mammaliantargetof pages 7-8) | mTOR: Its Critical Role in Metabolic Diseases, Cancer, and the Aging Process (2024), DOI: https://doi.org/10.3390/ijms25116141; Mammalian Target of Rapamycin (mTOR) Signalling Pathway—A Potential Target for Cancer Intervention: A Short Overview (2024), DOI: https://doi.org/10.2174/1874467217666230331081959 | Evidence here is largely mammalian-review level rather than mouse-only biochemistry, but it matches UniProt Q9JLN9 and canonical mTOR biology. |
| Kinase type / enzyme function | mTOR is the catalytic kinase in mTOR complexes and functions as a serine/threonine kinase of the PIKK family; recent structural work further indicates that activation is conformational and membrane-dependent. (cui2024structuralbasisfor pages 7-10, marafie2024mtoritscritical pages 1-3, basnet2024mammaliantargetof pages 2-4) | Structural basis for growth factor and nutrient signal integration on the lysosomal membrane by mTORC1 (2024 preprint), DOI: https://doi.org/10.1101/2024.11.15.623810; mTOR: Its Critical Role in Metabolic Diseases, Cancer, and the Aging Process (2024), DOI: https://doi.org/10.3390/ijms25116141; Mammalian Target of Rapamycin (mTOR) Signalling Pathway—A Potential Target for Cancer Intervention: A Short Overview (2024), DOI: https://doi.org/10.2174/1874467217666230331081959 | UniProt notes EC 2.7.11.1 with historical evidence; retrieved sources emphasize serine/threonine kinase activity. |
| Complexes / core subunits | mTOR assembles into mTORC1 and mTORC2. Retrieved sources list mTORC1 with Raptor, mLST8, PRAS40, and DEPTOR and mTORC2 with Rictor, mSIN1, mLST8, and DEPTOR; some reviews also include Tel2/Tti1 and Protor in broader subunit summaries. (marafie2024mtoritscritical pages 1-3, basnet2024mammaliantargetof pages 2-4, chen2024targetingthemtorautophagy pages 2-4) | mTOR: Its Critical Role in Metabolic Diseases, Cancer, and the Aging Process (2024), DOI: https://doi.org/10.3390/ijms25116141; Mammalian Target of Rapamycin (mTOR) Signalling Pathway—A Potential Target for Cancer Intervention: A Short Overview (2024), DOI: https://doi.org/10.2174/1874467217666230331081959; Targeting the mTOR-Autophagy Axis: Unveiling Therapeutic Potentials in Osteoporosis (2024), DOI: https://doi.org/10.3390/biom14111452 | Subunit lists vary slightly by review because some include assembly/stability cofactors whereas others emphasize core signaling subunits. |
| Canonical substrates / outputs | mTORC1 phosphorylates S6K1/2 and 4E-BP1/2, promoting translation and cell growth; mTORC2 promotes AKT Ser473 phosphorylation. Recent structural and functional work directly assays mTORC1 outputs using 4EBP1 and S6K. (cui2024structuralbasisfor pages 4-7, marafie2024mtoritscritical pages 1-3, basnet2024mammaliantargetof pages 2-4, cui2024structuralbasisfor pages 23-28) | Structural basis for growth factor and nutrient signal integration on the lysosomal membrane by mTORC1 (2024 preprint), DOI: https://doi.org/10.1101/2024.11.15.623810; mTOR: Its Critical Role in Metabolic Diseases, Cancer, and the Aging Process (2024), DOI: https://doi.org/10.3390/ijms25116141; Mammalian Target of Rapamycin (mTOR) Signalling Pathway—A Potential Target for Cancer Intervention: A Short Overview (2024), DOI: https://doi.org/10.2174/1874467217666230331081959 | Retrieved evidence is strongest for canonical mammalian substrates; substrate scope is broader in the full literature than summarized here. |
| Regulation by Rheb | Rheb-GTP is a direct activator of mTORC1; recent cryo-EM and reconstitution work shows strong activation when lipidated Rheb-GTP is presented on membranes and resolves a direct Rheb–mTOR interface. Rheb-GDP does not equivalently activate. (cui2024structuralbasisfor pages 4-7, cui2024structuralbasisfor pages 7-10, cui2024structuralbasisfor pages 23-28) | Structural basis for growth factor and nutrient signal integration on the lysosomal membrane by mTORC1 (2024 preprint), DOI: https://doi.org/10.1101/2024.11.15.623810 | Preprint evidence is highly mechanistic but not yet peer reviewed. |
| Regulation by Rag GTPases and Ragulator | Amino-acid signaling to mTORC1 occurs through Rag GTPases and Ragulator, which recruit and organize mTORC1 on lysosomal membranes; recent structural work reconstitutes an mTORC1–Rheb–Rag–Ragulator membrane complex and prior cited mechanisms support Rag–Raptor interaction. (cui2024structuralbasisfor pages 4-7, li2023hierarchicalinhibitionof pages 12-13, cui2024structuralbasisfor pages 23-28) | Structural basis for growth factor and nutrient signal integration on the lysosomal membrane by mTORC1 (2024 preprint), DOI: https://doi.org/10.1101/2024.11.15.623810; Hierarchical inhibition of mTORC1 by glucose starvation-triggered AXIN lysosomal translocation and by AMPK (2023), DOI: https://doi.org/10.1093/lifemeta/load005 | The 2023 AXIN/AMPK source supports the Ragulator and Rag framework mainly through cited mechanistic context rather than direct new structural data in the excerpt. |
| Regulation by TSC1/2 and Akt | Growth-factor and PI3K signaling activate Akt, which inhibits the TSC1/2 complex, thereby permitting Rheb-dependent mTORC1 activation. TSC2 is also referenced as the GAP opposing Rheb in structural and mechanistic context. (marafie2024mtoritscritical pages 1-3, basnet2024mammaliantargetof pages 2-4, cui2024structuralbasisfor pages 23-28) | mTOR: Its Critical Role in Metabolic Diseases, Cancer, and the Aging Process (2024), DOI: https://doi.org/10.3390/ijms25116141; Mammalian Target of Rapamycin (mTOR) Signalling Pathway—A Potential Target for Cancer Intervention: A Short Overview (2024), DOI: https://doi.org/10.2174/1874467217666230331081959; Structural basis for growth factor and nutrient signal integration on the lysosomal membrane by mTORC1 (2024 preprint), DOI: https://doi.org/10.1101/2024.11.15.623810 | Reviews summarize the pathway clearly; direct mouse-specific biochemical dissection in the retrieved set is limited. |
| Regulation by AMPK and AXIN | Energy stress inhibits mTORC1 through AXIN lysosomal translocation and AMPK. In the 2023 study, AXIN-mediated lysosomal events act early or primarily under glucose starvation, whereas AMPK additionally inhibits via Raptor and TSC2 phosphorylation, especially under severe stress. (li2023hierarchicalinhibitionof pages 12-13) | Hierarchical inhibition of mTORC1 by glucose starvation-triggered AXIN lysosomal translocation and by AMPK (2023), DOI: https://doi.org/10.1093/lifemeta/load005 | Excerpted evidence is summary-level; precise quantitative results from that study were not available in the retrieved passage. |
| Subcellular localization | A key operational localization for mTORC1 is the cytosolic face of the lysosomal membrane, where nutrient and growth-factor inputs converge. Raptor contributes to lysosomal surface localization and stability, and recent structural work maps direct membrane contacts by both mTOR and Raptor. (cui2024structuralbasisfor pages 7-10, chen2024targetingthemtorautophagy pages 2-4, cui2024structuralbasisfor pages 23-28) | Structural basis for growth factor and nutrient signal integration on the lysosomal membrane by mTORC1 (2024 preprint), DOI: https://doi.org/10.1101/2024.11.15.623810; Targeting the mTOR-Autophagy Axis: Unveiling Therapeutic Potentials in Osteoporosis (2024), DOI: https://doi.org/10.3390/biom14111452 | Retrieved evidence strongly supports lysosomal localization for mTORC1; it does not exclude additional cytoplasmic or other compartmental pools. |
| Quantitative finding: membrane reconstitution synergy | In Cui et al. 2024, liposomes plus Rag-Ragulator plus Rheb-GTP increased mTORC1 activity by more than 35-fold; Rheb-GTP on large unilamellar vesicles alone produced about a 3-fold increase. Experimental concentrations cited in the excerpt were 250 nM Rheb and 300 nM RagA/C-Ragulator. (cui2024structuralbasisfor pages 4-7) | Structural basis for growth factor and nutrient signal integration on the lysosomal membrane by mTORC1 (2024 preprint), DOI: https://doi.org/10.1101/2024.11.15.623810 | Strong quantitative mechanistic support, but from a preprint. |
| Quantitative finding: membrane geometry and distances | Cui et al. report a three-step lysosomal activation model in which Rag-Ragulator recruitment brings mTORC1 to within about 100 Å of the membrane, Rheb recruitment to within about 40 Å, and direct mTOR and Raptor membrane engagement completes activation; Rheb was positioned about 13 Å above the membrane in the structure. Smaller 30 to 50 nm liposomes reduced activity by about 65%. (cui2024structuralbasisfor pages 4-7, cui2024structuralbasisfor pages 23-28) | Structural basis for growth factor and nutrient signal integration on the lysosomal membrane by mTORC1 (2024 preprint), DOI: https://doi.org/10.1101/2024.11.15.623810 | Distances are structural-model estimates from membrane reconstitution, not direct in vivo intracellular distance measurements. |
| Quantitative finding: structural states and cell-based validation | Cui et al. resolved intermediate and active membrane-bound states at 3.61 Å and 3.16 Å. In inducible Raptor KO MEFs, rescue and perturbation experiments quantified pS6K and p4EBP1 with n = 3 experiments, reporting P < 0.0001 by two-way ANOVA with Dunnett’s multiple-comparisons test. (cui2024structuralbasisfor pages 7-10, cui2024structuralbasisfor pages 23-28) | Structural basis for growth factor and nutrient signal integration on the lysosomal membrane by mTORC1 (2024 preprint), DOI: https://doi.org/10.1101/2024.11.15.623810 | Useful for confidence in mechanistic conclusions, but still centered on mTORC1 rather than full Mtor biology across all tissues and contexts. |

Grade 3-5 treatment-related AEs included hyperglycemia 13% and fatigue 7%; MTD was 4 mg sapanisertib + 1,000 mg metformin. Preclinically, MLN0128 reduced phospho-sites at 10-30 nM and inhibited p-AKT S473 at 100 nM (subbiah2024phaseistudy pages 1-2, du2023bistericmtorc1inhibitors pages 1-2) | Subbiah et al., 2024, https://doi.org/10.1158/2767-9764.crc-22-0260; Du et al., 2023, https://doi.org/10.1172/jci167861; Marafie et al., 2024, https://doi.org/10.3390/ijms25116141 (subbiah2024phaseistudy pages 1-2, du2023bistericmtorc1inhibitors pages 1-2, marafie2024mtoritscritical pages 8-9) |

description: 'Mtor encodes mechanistic target of rapamycin, a large PI3K-related serine/threonine protein kinase. mTOR is the catalytic subunit of mTORC1 and mTORC2 complexes, integrating nutrient, growth-factor, energy, and stress inputs to regulate proximal outputs including translation, cell growth, autophagy, and AKT/PKC-family kinase signaling. Because mTOR is highly pleiotropic, tissue phenotypes and distal metabolic or developmental consequences are treated as non-core unless they directly describe TORC kinase signaling.'
