Function
FUNCTION: Serine/threonine protein kinase which is a central regulator of cellular metabolism, growth and survival in response to hormones, growth factors, nutrients, energy and stress signals (PubMed:12087098, PubMed:12150925, PubMed:12150926, PubMed:12231510, PubMed:12718876, PubMed:14651849, PubMed:15268862, PubMed:15467718, PubMed:15545625, PubMed:15718470, PubMed:18497260, PubMed:18762023, PubMed:18925875, PubMed:20516213, PubMed:20537536, PubMed:21659604, PubMed:23429703, PubMed:23429704, PubMed:25799227, PubMed:26018084, PubMed:29150432, PubMed:31112131, PubMed:31601708, PubMed:32561715, PubMed:34519269, PubMed:29236692, PubMed:37751742). MTOR directly or indirectly regulates the phosphorylation of at least 800 proteins (PubMed:15268862, PubMed:15467718, PubMed:17517883, PubMed:18925875, PubMed:18372248, PubMed:18497260, PubMed:20516213, PubMed:21576368, PubMed:21659604, PubMed:23429704, PubMed:29236692, PubMed:37751742). Functions as part of 2 structurally and functionally distinct signaling complexes mTORC1 and mTORC2 (mTOR complex 1 and 2) (PubMed:15268862, PubMed:15467718, PubMed:18925875, PubMed:18497260, PubMed:20516213, PubMed:21576368, PubMed:21659604, PubMed:23429704). In response to nutrients, growth factors or amino acids, mTORC1 is recruited to the lysosome membrane and promotes protein, lipid and nucleotide synthesis by phosphorylating key regulators of mRNA translation and ribosome synthesis (PubMed:12087098, PubMed:12150925, PubMed:12150926, PubMed:12231510, PubMed:12718876, PubMed:14651849, PubMed:15268862, PubMed:15467718, PubMed:15545625, PubMed:15718470, PubMed:18497260, PubMed:18762023, PubMed:18925875, PubMed:20516213, PubMed:20537536, PubMed:21659604, PubMed:23429703, PubMed:23429704, PubMed:25799227, PubMed:26018084, PubMed:29150432, PubMed:31112131, PubMed:34519269, PubMed:29236692). This includes phosphorylation of EIF4EBP1 and release of its inhibition toward the elongation initiation factor 4E (eiF4E) (PubMed:24403073, PubMed:29236692). Moreover, phosphorylates and activates RPS6KB1 and RPS6KB2 that promote protein synthesis by modulating the activity of their downstream targets including ribosomal protein S6, eukaryotic translation initiation factor EIF4B, and the inhibitor of translation initiation PDCD4 (PubMed:12150925, PubMed:12087098, PubMed:18925875, PubMed:29150432, PubMed:29236692). Stimulates the pyrimidine biosynthesis pathway, both by acute regulation through RPS6KB1-mediated phosphorylation of the biosynthetic enzyme CAD, and delayed regulation, through transcriptional enhancement of the pentose phosphate pathway which produces 5-phosphoribosyl-1-pyrophosphate (PRPP), an allosteric activator of CAD at a later step in synthesis, this function is dependent on the mTORC1 complex (PubMed:23429704, PubMed:23429703). Regulates ribosome synthesis by activating RNA polymerase III-dependent transcription through phosphorylation and inhibition of MAF1 an RNA polymerase III-repressor (PubMed:20516213). Activates dormant ribosomes by mediating phosphorylation of SERBP1, leading to SERBP1 inactivation and reactivation of translation (PubMed:36691768). In parallel to protein synthesis, also regulates lipid synthesis through SREBF1/SREBP1 and LPIN1 (By similarity). To maintain energy homeostasis mTORC1 may also regulate mitochondrial biogenesis through regulation of PPARGC1A (By similarity). In the same time, mTORC1 inhibits catabolic pathways: negatively regulates autophagy through phosphorylation of ULK1 (PubMed:32561715). Under nutrient sufficiency, phosphorylates ULK1 at 'Ser-758', disrupting the interaction with AMPK and preventing activation of ULK1 (PubMed:32561715). Also prevents autophagy through phosphorylation of the autophagy inhibitor DAP (PubMed:20537536). Also prevents autophagy by phosphorylating RUBCNL/Pacer under nutrient-rich conditions (PubMed:30704899). Prevents autophagy by mediating phosphorylation of AMBRA1, thereby inhibiting AMBRA1 ability to mediate ubiquitination of ULK1 and interaction between AMBRA1 and PPP2CA (PubMed:23524951, PubMed:25438055). mTORC1 exerts a feedback control on upstream growth factor signaling that includes phosphorylation and activation of GRB10 a INSR-dependent signaling suppressor (PubMed:21659604). Among other potential targets mTORC1 may phosphorylate CLIP1 and regulate microtubules (PubMed:12231510). The mTORC1 complex is inhibited in response to starvation and amino acid depletion (PubMed:12150925, PubMed:12150926, PubMed:24403073). The non-canonical mTORC1 complex, which acts independently of RHEB, specifically mediates phosphorylation of MiT/TFE factors MITF, TFEB and TFE3 in the presence of nutrients, promoting their cytosolic retention and inactivation (PubMed:22576015, PubMed:22343943, PubMed:22692423, PubMed:24448649, PubMed:32612235, PubMed:36608670, PubMed:36697823). Upon starvation or lysosomal stress, inhibition of mTORC1 induces dephosphorylation and nuclear translocation of TFEB and TFE3, promoting their transcription factor activity (PubMed:22576015, PubMed:22343943, PubMed:22692423, PubMed:24448649, PubMed:32612235, PubMed:36608670). The mTORC1 complex regulates pyroptosis in macrophages by promoting GSDMD oligomerization (PubMed:34289345). MTOR phosphorylates RPTOR which in turn inhibits mTORC1 (By similarity). As part of the mTORC2 complex MTOR may regulate other cellular processes including survival and organization of the cytoskeleton (PubMed:15268862, PubMed:15467718). mTORC2 plays a critical role in the phosphorylation at 'Ser-473' of AKT1, a pro-survival effector of phosphoinositide 3-kinase, facilitating its activation by PDK1 (PubMed:15718470). mTORC2 may regulate the actin cytoskeleton, through phosphorylation of PRKCA, PXN and activation of the Rho-type guanine nucleotide exchange factors RHOA and RAC1A or RAC1B (PubMed:15268862). mTORC2 also regulates the phosphorylation of SGK1 at 'Ser-422' (PubMed:18925875). Regulates osteoclastogenesis by adjusting the expression of CEBPB isoforms (By similarity). Plays an important regulatory role in the circadian clock function; regulates period length and rhythm amplitude of the suprachiasmatic nucleus (SCN) and liver clocks (By similarity). Phosphorylates SQSTM1, promoting interaction between SQSTM1 and KEAP1 and subsequent inactivation of the BCR(KEAP1) complex (By similarity). {ECO:0000250|UniProtKB:Q9JLN9, ECO:0000269|PubMed:12087098, ECO:0000269|PubMed:12150925, ECO:0000269|PubMed:12150926, ECO:0000269|PubMed:12231510, ECO:0000269|PubMed:12718876, ECO:0000269|PubMed:14651849, ECO:0000269|PubMed:15268862, ECO:0000269|PubMed:15467718, ECO:0000269|PubMed:15545625, ECO:0000269|PubMed:15718470, ECO:0000269|PubMed:17517883, ECO:0000269|PubMed:18372248, ECO:0000269|PubMed:18497260, ECO:0000269|PubMed:18762023, ECO:0000269|PubMed:18925875, ECO:0000269|PubMed:20516213, ECO:0000269|PubMed:20537536, ECO:0000269|PubMed:21576368, ECO:0000269|PubMed:21659604, ECO:0000269|PubMed:22343943, ECO:0000269|PubMed:22576015, ECO:0000269|PubMed:22692423, ECO:0000269|PubMed:23429703, ECO:0000269|PubMed:23429704, ECO:0000269|PubMed:23524951, ECO:0000269|PubMed:24403073, ECO:0000269|PubMed:24448649, ECO:0000269|PubMed:25438055, ECO:0000269|PubMed:25799227, ECO:0000269|PubMed:26018084, ECO:0000269|PubMed:29150432, ECO:0000269|PubMed:29236692, ECO:0000269|PubMed:30704899, ECO:0000269|PubMed:31112131, ECO:0000269|PubMed:31601708, ECO:0000269|PubMed:32561715, ECO:0000269|PubMed:32612235, ECO:0000269|PubMed:34289345, ECO:0000269|PubMed:34519269, ECO:0000269|PubMed:36608670, ECO:0000269|PubMed:36691768, ECO:0000269|PubMed:36697823, ECO:0000269|PubMed:37751742}.

Structure
SUBUNIT: Part of the mechanistic target of rapamycin complex 1 (mTORC1) which contains MTOR, MLST8 and RPTOR (PubMed:12150925, PubMed:12150926, PubMed:12408816, PubMed:12718876, PubMed:18925875, PubMed:24403073, PubMed:20542007, PubMed:23636326, PubMed:27909983, PubMed:26678875, PubMed:29236692, PubMed:31601764, PubMed:34519268, PubMed:36697823, PubMed:34519269). The mTORC1 complex is a 1 Md obligate dimer of two stoichiometric heterotetramers with overall dimensions of 290 A x 210 A x 135 A (PubMed:20542007, PubMed:23636326). It has a rhomboid shape and a central cavity, the dimeric interfaces are formed by interlocking interactions between the two MTOR and the two RPTOR subunits (PubMed:20542007, PubMed:27909983, PubMed:23636326). The MLST8 subunit forms distal foot-like protuberances, and contacts only one MTOR within the complex, while the small AKT1S1/PRAS40 localizes to the midsection of the central core, in close proximity to RPTOR (PubMed:20542007, PubMed:23636326, PubMed:27909983, PubMed:29236692). mTORC1 associates with AKT1S1/PRAS40, which inhibits its activity by blocking MTOR substrate-recruitment site (PubMed:17386266, PubMed:29236692). Part of the mechanistic target of rapamycin complex 2 (mTORC2) which contains MTOR, MLST8, PRR5, RICTOR, MAPKAP1 and DEPTOR (PubMed:15268862, PubMed:15467718, PubMed:17599906, PubMed:18925875). Interacts with PLPP7 and PML (By similarity). Interacts with PRR5 and RICTOR; the interaction is direct within the mTORC2 complex and interaction with RICTOR is enhanced by deubiquitination of RICTOR by USP9X (PubMed:17599906, PubMed:33378666, PubMed:34519268). mTORC1 and mTORC2 associate with DEPTOR, which regulates its activity (PubMed:19446321, PubMed:34519268, PubMed:34519269). Interacts with WAC; WAC positively regulates MTOR activity by promoting the assembly of the TTT complex composed of TELO2, TTI1 and TTI2 and the RUVBL complex composed of RUVBL1 and RUVBL2 into the TTT-RUVBL complex which leads to the dimerization of the mTORC1 complex and its subsequent activation (PubMed:26812014). Interacts with UBQLN1 (PubMed:11853878). Interacts with TTI1 and TELO2 (PubMed:20801936, PubMed:20427287, PubMed:20810650). Interacts with CLIP1; phosphorylates and regulates CLIP1 (PubMed:12231510). Interacts with NBN (PubMed:23762398). Interacts with HTR6 (PubMed:23027611). Interacts with BRAT1 (PubMed:25657994). Interacts with MEAK7 (via C-terminal domain); the interaction increases upon nutrient stimulation (PubMed:29750193). Interacts with TM4SF5; the interaction is positively regulated by arginine and is negatively regulated by leucine (PubMed:30956113). Interacts with GPR137B (PubMed:31036939). Interacts with NCKAP1L (PubMed:32647003). Interacts with TPCN1 and TPCN2; the interaction is required for TPCN1 and TPCN2 sensitivity to ATP (PubMed:23394946). Interacts with ATP6V1A and with CRYAB, forming a ternary complex (By similarity). Interacts with SLC38A7; this interaction mediates the recruitment of mTORC1 to the lysosome and its subsequent activation (PubMed:35561222). {ECO:0000250|UniProtKB:Q9JLN9, ECO:0000269|PubMed:11853878, ECO:0000269|PubMed:12150925, ECO:0000269|PubMed:12150926, ECO:0000269|PubMed:12231510, ECO:0000269|PubMed:12408816, ECO:0000269|PubMed:12718876, ECO:0000269|PubMed:15268862, ECO:0000269|PubMed:15467718, ECO:0000269|PubMed:17386266, ECO:0000269|PubMed:17599906, ECO:0000269|PubMed:18925875, ECO:0000269|PubMed:19446321, ECO:0000269|PubMed:20427287, ECO:0000269|PubMed:20542007, ECO:0000269|PubMed:20801936, ECO:0000269|PubMed:20810650, ECO:0000269|PubMed:23027611, ECO:0000269|PubMed:23394946, ECO:0000269|PubMed:23636326, ECO:0000269|PubMed:23762398, ECO:0000269|PubMed:24403073, ECO:0000269|PubMed:25657994, ECO:0000269|PubMed:26678875, ECO:0000269|PubMed:26812014, ECO:0000269|PubMed:27909983, ECO:0000269|PubMed:29236692, ECO:0000269|PubMed:29750193, ECO:0000269|PubMed:30956113, ECO:0000269|PubMed:31036939, ECO:0000269|PubMed:31601764, ECO:0000269|PubMed:32647003, ECO:0000269|PubMed:33378666, ECO:0000269|PubMed:34519268, ECO:0000269|PubMed:34519269, ECO:0000269|PubMed:35561222, ECO:0000269|PubMed:36697823}.
Post-translational modification
PTM: Autophosphorylates when part of mTORC1 or mTORC2 (PubMed:9434772, PubMed:15467718). Phosphorylation at Ser-1261, Ser-2159 and Thr-2164 promotes autophosphorylation (PubMed:19487463). Phosphorylation in the kinase domain modulates the interactions of MTOR with RPTOR and AKT1S1/PRAS40 and leads to increased intrinsic mTORC1 kinase activity (PubMed:15905173, PubMed:19145465, PubMed:21576368). Phosphorylation at Ser-2159 by TBK1 in response to growth factors and pathogen recognition receptors promotes mTORC1 activity (PubMed:29150432). Phosphorylation at Thr-2173 in the ATP-binding region by AKT1 strongly reduces kinase activity (PubMed:24247430). {ECO:0000269|PubMed:15467718, ECO:0000269|PubMed:15905173, ECO:0000269|PubMed:19145465, ECO:0000269|PubMed:19487463, ECO:0000269|PubMed:21576368, ECO:0000269|PubMed:24247430, ECO:0000269|PubMed:29150432, ECO:0000269|PubMed:9434772}.
