Fig. 4. The IMP complex localizes to mitochondria but not to peroxisomes.

a Localization of Imp2-3xMyc was analyzed by density gradient centrifugation using purified organelles also containing the peroxisomal membrane protein Ant1 fused to YFP. Fraction were collected from the top of the gradient and analyzed by SDS–PAGE and western blot. Por1 is a protein located in the outer membrane of mitochondria. b Activity of Imp2-3xMyc was studied by analyzing the processing of the truncated Ptc5 variant Ptc51–201-RFP-HA. c Migration of Ptc51–201-RFP-PTS either containing (+MTS) or lacking (−MTS) the mitochondrial presequence was examined by SDS–PAGE and western blot. d The subcellular localization of ∆MTS Ptc51–201-RFP-PTS was investigated using fluorescence microscopy. White color indicates colocalization with the peroxisomal protein Ant1-YFP. Source data are provided in the Source data file.
