Function
Non-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. The TSC-TBC complex 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. Within the TSC-TBC complex, TSC1 stabilizes TSC2 and prevents TSC2 self-aggregation. Acts as a tumor suppressor. Involved in microtubule-mediated protein transport via its ability to regulate mTORC1 signaling. Also acts as a co-chaperone for HSP90AA1 facilitating HSP90AA1 chaperoning of protein clients such as kinases, TSC2 and glucocorticoid receptor NR3C1. Increases ATP binding to HSP90AA1 and inhibits HSP90AA1 ATPase activity. Competes with the activating co-chaperone AHSA1 for binding to HSP90AA1, thereby providing a reciprocal regulatory mechanism for chaperoning of client proteins. Recruits TSC2 to HSP90AA1 and stabilizes TSC2 by preventing the interaction between TSC2 and ubiquitin ligase HERC1.
Tissue Specificity Highly expressed in skeletal muscle, followed by heart, brain, placenta, pancreas, lung, liver and kidney . Also expressed in embryonic kidney cells .
