We previously identified the Rab1A small GTPase as a conserved activator of mTORC1 in response to amino acid (AA) stimulation in yeast and mammalian cells. To better understand the physiological function of Rab1A- mTORC1 signaling in vivo, we genetically engineered conditional Rab1A knockout (Rab1A-KO) in mice. We found that tamoxifen-induced Rab1A knockout in young adult […]
