Immune fluorescence microscopy shows that the key UPS regulator, GRASP55, localizes primarily at the Golgi apparatus in non-stressed cells (left panel), whereas it readily relocalizes to secretory vesicles in response to stimuli that cause mTORC1 inhibition (middle panel). mTORC1 regulates GRASP55 directly at the Golgi, where both proteins colocalize in non-stressed cells (right panel, Image taken with the electron microscope).
