TRAF2 and OTUD7B govern a ubiquitin-dependent switch that regulates mTORC2 signalling.

ABSTRACT: The mechanistic target of rapamycin (mTOR) has a key role in the integration of various physiological stimuli to regulate several cell growth and metabolic pathways. mTOR primarily functions as a catalytic subunit in two structurally related but functionally distinct multi-component kinase complexes, mTOR complex 1 (mTORC1) and mTORC2 (refs 1, 2). Dysregulation of mTOR signalling is associated with a variety of human diseases, including metabolic disorders and cancer. Thus, both mTORC1 and mTORC2 kinase activity is tightly controlled in cells. mTORC1 is activated by both nutrients and growth factors, whereas mTORC2 responds primarily to extracellular cues such as growth-factor-triggered activation of PI3K signalling. Although both mTOR and GβL (also known as MLST8) assemble into mTORC1 and
