| description | Rheb is a Ras-like small GTPase essential for TORC1 activity in mammals []. Rheb activates the protein kinase activity of mTORC1 (rapamycin), and in turn stimulates the phosphorylation of S6K1 and EIF4EBP1 through activation of mTORC1 signaling [, , ]. Rheb alternates between an inactive form bound to GDP and an active form bound to GTP. It is inactivated by TSC1-TSC2 via the GTPase activating protein (GAP) domain of TSC2 []. The mechanism of action of Rheb has been determined from the tertiary structure []. |
