K13 shows an increased association with the mitochondria post DHA pulse. (B) Representative fluorescence microscopy images and 3D reconstructions of NF54WT-attBGFP-K13WT (left) or NF54WTattB-3HA-K13C580Y (right) ring-stage parasites co-stained with MitoTracker Deep Red and anti-GFP antibodies. (E) Representative fluorescence microscopy images and 3D reconstructions of Cam3.IIR539T ring-stage parasites 12h post DHA pulse or DMSO mock treatment. Scale bars: 1 μm. (F) Representative IEM images of NF54WTattB-3HA-K13C580Y trophozoites treated with DHA (9 nM for 3h) or a DMSO vehicle control and stained with anti-HA antibodies to detect K13. Arrowhead highlights location of interest. M, mitochondria; N, nucleus. Scale bar: 100 nm. (G) 3D volume reconstruction of untreated late Cam3.IIR539T and Cam3.IIWT trophozoites triply stained with MitoTracker, anti-BIP (ER, green) and anti-K13 E3 (purple).
