Figure 6. p62 regulates mTOR translocation to the lysosomal compartment.
Starved or restimulated 293 cells were co-immunostained for p62 and (A) LAMP2, (B) RagC, (C) mTOR, or (D) raptor. (E) p62fl/fl MEFs infected with GFP or CRE adenovirus and overexpressing activated RagB were starved for 4 h and then restimulated with amino acids for 10 min. Afterwards, they were co-immunostained for mTOR and LAMP2. (F) Images of WT and p62 KO immortal MEFs co-immunostained for RagC and LAMP2. In all images, inserts show selected fields that were magnified two or five times to show areas of staining overlap (Merge). Scale bars=10 µm. Images are representative of three experiments.
