Cells were selected for imaging y viewing in the SNX1 channel without viewing the GLUT-1 staining so as to avoid iasing the oserved GLUT-1 localisation. The knockdown of VPS shifts the localization of GLUT1 to intracellular structures. The expression of GFP-tagged VPS can rescue GLUT-1 localisation ut the mutant displays GLUT-1 localisation more similar to a VPS KD in untransfected HeLa cells.
