PF3D7_0918600 ATP-dependent DNA helicase Q1; bloom protein homolog

Mitochondrial localization of PfBlm and PfRad51. Immunofluorescence images displaying localization of PfBlm-GFP and PfRad51-GFP (green) to mitochondria (red) and/or nucleus (blue) of Plasmodium falciparum parasite. Anti-CytC antibody and Hoechst dye were used to stain parasite mitochondria and the nucleus, respectively. IFA using anti-GFP in 3D7 and preimmune sera in PfBlm-GFP transfected parasite served as the experimental negative controls. IFA was performed with trophozoite and schizont parasites as indicated. DIC, differential interference contrast. Colocalization of signals from GFP-tagged PfRad51 or PfBlm with CytC confirmed the mitochondrion localization of PfRad51 or PfBlm in both the trophozoite and schizont stages. As expected, GFP-tagged PfRad51 or PfBlm proteins were also found in the parasite nucleus.
