Expression of R98F PINK1-YFP (green) induces mitochondrial translocation of mCherry-Parkin (red) in the presence of the mitochondrial depolarizing agent CCCP (carbonyl cyanide-m-chlorophenyl hydrazone), indicating that this PINK1 mutant is functional for inducing Parkin translocation when located on the outer michondrial membrane. The R98F mutation in PINK1-YFP partially inhibits proteolytic cleavage. Transfected HeLa cells were treated with CCCP (10 µM) for 1 hr. Live cell imaging was performed on an LSM510 Meta (Carl Zeiss, Inc) with a 63x 1.4 NA oil differential interference contrast Plan Apo objective. Image contrast and brightness were adjusted in the LSM image browser (Zeiss). This image corresponds to Fig 4e, bottom row, with DMSO control in Fig 4e, top row of J Cell Biol, 191: 933-942, 2010. Images in Fig 4 include CIL#s 13733, 13734, 13729, 13730, 13731, 13732, 13717, 13718, 13719, 13720, 13721, 13722, 13723, 13724.
