3. Cycling between the inactive GDP- and the active GTP-bound state modulates the backbone dynamics of a C-terminal truncated form, RhebDeltaCT, which is suggested to influence its interactions. We further investigated the interactions between RhebDeltaCT and the proposed Rheb-binding domain of the regulatory protein FKBP38.

14. activation of mTOR signalling via RHEB over-expression inhibited the starvation-induced autophagy but did not affect trafficking of tf-Amyloid precursor protein (APP). These results show tf-APP can be used to determine how APP is trafficked through the lysosomal system of the cell.

15. Data suggest DNM2/RRAGB- (or DNM2/RRAGC-)dependent endocytosis of extracellular amino acids (AAs) plays critical role in mTORC1 transport/activation; recruitment of mTORC1 from cytoplasm to lysosome is suppressed by DNM2 inhibition; AA deprivation appears to be main cause of mTORC1 inactivation via DNM2 inhibition. (RHEB = Ras homolog enriched in brain; DNM2 = dynamin II; RRAG = Ras-related GTP binding protein)

16. By interfering with TSC-Rheb complex, arginine relieves allosteric inhibition of Rheb by TSC. Arginine cooperates with growth factor signaling which further promotes dissociation of TSC2 from lysosomes and activation of mTORC1.

17. Data show that Rheb/p27 axis induces autophagy-dependent cancer cell survival under stress conditions.

18. Mutations in the TSC2-RHEB-mTOR signaling axis may lead to a loss of inhibitory inputs thus conferring a survival advantage to a dividing tumor cell.

Mouse (Murine) Ras Homolog Enriched in Brain (RHEB) interaction partners

1. Compensatory cardiac hypertrophy activates ER stress and ATF6, which induces RHEB and activates mTORC1. Thus, ATF6 is a previously unrecognized link between growth stimuli and mTORC1-mediated cardiac growth.

2. These results suggest that inter-organelle communication between the Golgi and lysosome is important for mTORC1 regulation and the Golgi-localized Rheb may activate mTORC1 at Golgi-lysosome contact site.

3. This study found that cRheb expression promoted regeneration of injured rVRG axons into the lesion site, while we observed no rVRG axon regrowth with AAV2-GFP control.

4. Rheb1 is critical for the polarization of macrophages and inhibition of allergic asthma. Deletion of Rheb1 enhances M2 polarization but decreases M1 polarization in alveolar macrophages, leading to the aggravation of OVA-induced allergic asthma.

5. Ggpps deletion enhanced Rheb farnesylation, which subsequently activated mTORC1 and facilitated spermatogonial differentiation

6. Thus, the various regulatory elements that impinge upstream of mTORC1 activation pathways are differentially required for HSC homeostasis in vivo.

7. Forebrain depletion of Rheb GTPase elicits spatial memory deficits.

8. Rheb is an important negative regulator of beige fat development and thermogenesis. Rheb is able to suppress the beiging effect through an mTORC1-independent mechanism, via PDE4D5-dependent downregulation of the cAMP-PKA signaling pathway.

10. Rheb1 is critical for macrophage production and phagocytosis and executes these activities possibly via mTORC1-dependent pathway.

11. EAAT4 was downregulated due to the loss of Rheb1 in Purkinje cells; mTORC1 was downregulated and Akt was upregulated in Rheb1 cKO mice, suggesting that mTORC1 and Akt may be related to the downregulation of EAAT4; Rheb1 knockout decreased EAAT4 currents and slowed down the kinetics of AMPA currents; Rheb1 deficiency did not affect the morphology of Purkinje cell layer and the development of Purkinje cells
