Stimulates the phosphorylation of S6K1 and EIF4EBP1 through activation of mTORC1 signaling. Activates the protein kinase activity of mTORC1. Has low intrinsic GTPase activity.Farnesylation is important for efficiently activating mTORC1-mediated signaling. Phosphorylation by MAPKAPK5 impairs GTP-binding and inactivation.
