WebAug 19, 2024 · Subsequent analysis revealed that the Ragulator-Rag complex controls mTORC1-dependent events that operate downstream of GSDMD cleavage to promote GSDMD oligomerization and pore formation, by a process mediated by mitochondrial reactive oxygen species (ROS). WebAug 10, 2012 · Rag-dependent recruitment of mTORC1 to the lysosome is an essential step in the activation of mTORC1 by amino acids. We next examined if glutaminolysis is required for the recruitment of mTORC1 to the lysosome. Knockdown of GLS or GDH blocked leucine and glutamine-stimulated translocation of mTORC1 to the lysosome ( Figures 3 A and 3B ).
