Web2 Feb 2024 · The mechanistic target of rapamycin (mTOR) (initially known as mammalian target of rapamycin) is a master kinase that coordinates the cellular metabolic response to different signals including nutrients (e.g., amino acids, glucose, lipids, cholesterol), cellular energy, growth factors (e.g., insulin-like growth factor (IGF)), and oxygen. In turn, … Web11 Nov 2014 · Sestrins are stress-responsive proteins that inhibit mTORC1 via activation of AMP-activated protein kinase (AMPK) and tuberous sclerosis complex. Here we report an …
Web2 Dec 2016 · Sestrins (Sesn1, Sesn2 and Sesn3) are a family stress-inducible, redox-sensitive proteins that are involved in cellular- or organism-level adaptation to diverse metabolic challenges. They have been identified as direct interactors of GATOR2 and shown to inhibit mTORC1 by preventing GATOR2 from inhibiting GATOR1 in presence of amino … WebSESTRINs, a protein family composed of SESTRIN1, SESTRIN2, and SESTRIN3 in mammals, are potent suppressors of the mechanistic target of rapamycin complex 1 (mTORC1) kinase. 1 mTORC1 integrates numerous signals from nutrients, growth factors, and stress to control metabolism, autophagy, and cell growth. mTORC1 activity inversely correlates with …
