PF3D7_0720700 phosphoinositide-binding protein px1

Subcellular localization of PfPX1-GFP. (A) Anti-GFP western blot of mixed stage PfPX1-GFP parasites showing the expression of the fusion protein. (B) Live cell imaging of the PfPX1-GFP parasite line at 3 different stages. Troph: trophozoite. (C) Colocalization of PfPX1-GFP with the endolysosomal marker PfVPS45-mScarlet. White arrow shows the overlapping foci. (D) Colocalization of PfPX1-GFP with PfAP2m-mScarlet. White arrow shows the overlapping foci. (E) Colocalization of PfPX1-GFP with PfKelch13 (K13) using an anti-PfK13 antibody. White arrow shows the overlapping foci. (F) PfPX1-GFP in red blood cells preloaded with dextran Alexa-594. (F, iv) Colocalization of PfPX1-GFP with LysoTracker. White arrow in iii and iv show the DV extension. Single optical slices shown. (G) Colocalization of PfPX1-GFP with hemoglobin-filled structures. White arrow shows the overlapping foci. (H) Colocalization of PfPX1-GFP with mScarlet-PfRab5a. White arrow shows the juxtaposed foci. (I) Colocalization of PfPX1-GFP with mScarlet-PfRab7. White arrow shows the juxtaposed foci. Dapi: parasite nuclei.
