PINK1-YFP R98F (green) is found localized to mitochondria (red) in the presence of the mitochondrial depolarizing agent CCCP (carbonyl cyanide-m-chlorophenyl hydrazone). The R98F mutation in PINK1-YFP partially inhibits proteolytic cleavage. HeLa cells expressing PINK1-YFP R98F were stained with 10nM MitoTracker Red for 30 min to see mitochondrial morphology and then treated with 10µM CCCP for 3 hours. Cells were imaged using an inverted microscope (LSM510 Meta; Carl Zeiss, Inc.) with a 63× 1.4 NA oil differential interference contrast Plan Apo objective. Image contrast and brightness were adjusted in the accompanying image browser (LSM; Carl Zeiss, Inc.). This image corresponds to Fig 3d, R98F/CCCP bottom panels in J Cell Biol. 191: 933-942, 2010. Images in Fig3d include CIL#s 13713, 13714, 13715, 13716.
