Kog1/Raptor mediates metabolic rewiring during nutrient limitation by controlling SNF1/AMPK activity
Abstract In changing environments, cells modulate resource budgeting through distinct metabolic routes to control growth. Accordingly, the TORC1 and SNF1/AMPK pathways operate contrastingly in nutrient replete or limited environments to maintain homeostasis. The functions of TORC1 under glucose and amino acid limitation are relatively unknown. We identified a modified form of the yeast TORC1 component Kog1/Raptor, which exhibits delayed growth exclusively during glucose and amino acid limitations.
Anabolic SIRT4 Exerts Retrograde Control over TORC1 Signaling by Glutamine Sparing in the Mitochondria
Research Article Eisha Shaw, Manasi Talwadekar, Zeenat Rashida, Nitya Mohan, Aishwarya Acharya, Subhash Khatri, Sunil Laxman, Ullas Kolthur-Seetharam DOI: 10.1128/MCB.00212-19 ABSTRACT Anabolic and catabolic signaling mediated via mTOR and AMPK (AMP-activated kinase) have to be intrinsically coupled to mitochondrial functions for maintaining homeostasis and mitigate cellular/organismal stress.
