Web17 Jan 2024 · SESTRINS have been proposed to repress mTORC1 through at least three different mechanisms: (i) by activating AMPK (AMP-activated protein kinase) and the TSC complex (Budanov & Karin, 2008 ), (ii) by acting as a GDI (guanosine dissociation inhibitor) to prevent GDP dissociation from RAGA/B (Peng et al, 2014 ), and (iii) by binding and … Web2 Jul 2024 · The mTOR signaling controls essential biological functions including proliferation, growth, metabolism, autophagy, ageing, and others. Hyperactivation of mTOR signaling leads to a plethora of human disorders; thus, mTOR is an attractive drug target.
Web1 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 AMPK-independent mechanism of mTORC1 inhibition by Sestrins mediated by their interaction with GATOR2. Web6 Mar 2024 · Nutrient sensing by cells is crucial, and when this sensing mechanism is disturbed, human disease can occur. mTOR complex 1 (mTORC1) senses amino acids to control cell growth, metabolism, and autophagy.
