WebTSC1 and TSC2 proteins serve as a meeting point for the complex intracellular signaling pathways that include insulin signaling (PI3K–AKT), mitogenic signaling (MAPK), and energy sensing (AMPK). The main output pathway of TSC2:TSC1 is the mTOR protein complex, and under normal homeostatic conditions, TSC2:TSC1 stops mTOR activation. 34,36 The ...
