| Post Translational Modifications | Phosphorylation at Ser-939 and Thr-1462 by PKB/AKT1 in response to insulin signaling and growth factor stimulation inhibits the ability of the TSC-TBC complex to suppress mTORC1 signaling: phosphorylation promotes dissociation of the TSC-TBC complex from lysosomal membranes, leading to activation of mTORC1 by RHEB. Phosphorylation at Ser-1387, Ser-1418 or Ser-1420 does not affect interaction with TSC1. Phosphorylation by AMPK activates it and leads to negative regulation of the mTORC1 complex. Phosphorylated at Ser-1798 by RPS6KA1.phosphorylation inhibits TSC2 ability to suppress mTORC1 signaling. Phosphorylated by DAPK1. Ubiquitinated by the DCX(FBXW5) E3 ubiquitin-protein ligase complex, leading to its subsequent degradation. Ubiquitinated by MYCBP2 independently of its phosphorylation status leading to subsequent degradation.association with TSC1 protects from ubiquitination. |
| Function | Catalytic component of the TSC-TBC complex, a multiprotein complex that acts as a negative regulator of the canonical mTORC1 complex, an evolutionarily conserved central nutrient sensor that stimulates anabolic reactions and macromolecule biosynthesis to promote cellular biomass generation and growth. Within the TSC-TBC complex, TSC2 acts as a GTPase-activating protein (GAP) for the small GTPase RHEB, a direct activator of the protein kinase activity of mTORC1. In absence of nutrients, the TSC-TBC complex inhibits mTORC1, thereby preventing phosphorylation of ribosomal protein S6 kinase (RPS6KB1 and RPS6KB2) and EIF4EBP1 (4E-BP1) by the mTORC1 signaling. The TSC-TBC complex is inactivated in response to nutrients, relieving inhibition of mTORC1. Involved in microtubule-mediated protein transport via its ability to regulate mTORC1 signaling. Also stimulates the intrinsic GTPase activity of the Ras-related proteins RAP1A and RAB5. |
