Kelch13 location and interactome. (Left panel) Fluorescence microscopy images showing parasites with endogenously GFP-tagged Kelch13 (K13) (17) with coexpressed STVR-SDEL (ER), Sec13p (ER exit sites), P40 (phosphatidylinositol 3-phosphate sensor: food vacuole), ACP (apicoplast), or endogenously GFP-tagged mutated Kelch13 (K13C580Y) with episomal mCherry-Kelch13wt.
(Right panel) Fluorescence microscopy in parasites with endogenously GFP-tagged DiQ-BioID hits (KIC1-10 or short name) colocalized with episomal mCherry-Kelch13. Arrowheads indicate Kelch13 foci overlapping with the KIC signal. Scale bars, 5 mm. Merge, merged green and red channel; DAPI, 4′,6-diamidino-2-phenylindole (nuclei).
