(A) The mTORC1 and mTORC2 signaling pathways.
(B) mTORC1 subunits and respective binding sites on mTOR. The 5.9-A° cryo-EM structure of mTORC1 in complex with the FKBP12-rapamycin complex (without DEPTOR and PRAS40, PDB: 5FLC) is depicted as a space filling model and colored by subunit.

Figure 2. The mTOR Signaling Network

(A) The signaling pathways upstream of mTORC1 and mTORC2. Positive regulators of mTORC1 signaling are shown in yellow, while negative regulators are shown in blue. mTORC1 and mTORC2 are shown in green and red, respectively.
(B) The major pathways downstream of mTORC1 signaling in mRNA translation, metabolism, and protein turnover.
(C) mTORC1 controls the activity of several transcription factors that can also be independently regulated by cell stress.
(D) The major pathways downstream of mTORC2 signaling response

(A) mTORC1 controls the balance between anabolism合成代谢 and catabolism 分解代谢in response to fasting禁食 and feeding喂食.
(B) The effect of cumulative mTORC1 activity on overall health.
(C) The effect of mTORC1 hyperactivation超活化 in pancreatic胰腺 b cells on glucose tolerance over time.
(D) The normal functions of mTORC1 in the liver, muscle, pancreas胰腺, and adipose tissue脂肪组织 (left), and the consequences of chronic mTORC1 inhibition (middle) or activation (right).
(E) Deregulation of mTORC1 signaling in insulin resistance/diabetes糖尿病, and the effect of rapamycin or a theoretical mTORC1-specific inhibitor.
(F) Constitutive activation (red) and inhibition (purple) of mTORC1 signaling in the muscle leads to atrophy萎缩, whereas optimal muscle growth and function requires alternating periods of high and low mTORC1 activity (blue).
