Catalytically active TSC1 bound to TSC2 inhibits MTOR. 3 / 3

"Akt then phosphorylates several substrates, one of which is the tuberous sclerosis complex (TSC1/2), a GTPase activating protein complex that suppresses Rheb, a GTPase that contributes directly to the activation of mTOR"

"Genetic support for a linear Akt1-mTOR-p70S6K pathway has recently come from reports demonstrating that the tuberous sclerosis complex 1 and 2 proteins (Tsc1 and Tsc2) can inhibit mTOR (Fig. 1). Akt1 phosphorylates Tsc2, thereby activating mTOR at least in part by disrupting the Tsc1-Tsc2 complex [54]."

"TSC2, in a complex with TSC1, normally represses signalling through mTOR, and phosphorylation by Akt/PKB inhibits this function of TSC2 (for review, see Manning & Cantley, 2003)."
