Sestrins gator mtorc1
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 … WebSestrins are stress-inducible metabolic regulators that suppress a wide range of age- and obesity-associated pathologies, many of which are due to mTORC1 overactivation. Upon various stresses,...
