PF3D7_1230400 ATP-dependent protease subunit ClpQ

Upper panel: Immunofluorescence assay showing transgenic parasites expressing PfClpQ(mut)-HA-ddFKBP (ClpQ(mut)-DD parasite line) immuno-stained with anti-HA antibodies and co-stained for mitochondria with MitoTracker. The parasite nuclei were stained with DAPI and slides were visualized by fluorescence microscope. the immunofluorescence staining overlapped with the MitoTracker staining suggesting that the fusion protein is localized in the mitochondria which is the site of action of native protein

Lower panel: Fluorescent microscopic images of MitoTracker stained ClpQ(mut)-DD transgenic parasites at different time points (lower panel). The mitochondria in control ClpQ(mut)-DD set showed normal growth and development; in majority of these parasites at trophozoite stage the mitochondria appeared as elongated structures, in late trophozoite/early schizont stage) most of these mitochondria showed branched structure.
