RCSB PDB - 6U62: Raptor-Rag-Ragulator complex

Splet10. okt. 2024 · Rogala et al. determined the structure of the Raptor-Rag-Ragulator complex at 3.2-angstrom resolution by cryo–electron microscopy. The structure shows why Raptor binds only to a specific nucleotide conformation of the Rag heterodimer and suggests a model for how mTORC1 would dock onto the lysosomal surface, which is a key step in its … SpletThe Ragulator complex tethers the Rag heterodimer to the lysosomal surface, and the SLC38A9 transmembrane protein is a lysosomal arginine sensor that upon activation stimulates mTORC1 activity through the Rag GTPases. How Ragulator and SLC38A9 control the nucleotide loading state of the Rag GTPases remains incompletely understood. Splet01. maj 2024 · How these inputs regulate mTORC1 signaling at a molecular level is becoming clearer, as highlighted in the study of Rogala et al.
