Subcellular localization of PfUT (ubiquitin-transferase). P. falciparum-infected erythrocytes at the trophozoite stage were fixed and analyzed by immunofluorescence assays using antisera to the ER marker BiP (rabbit, 1:1000), the Golgi marker ERD2 (rat, 1:500), and the N- (panels 1 and 5, rabbit, 1:3000; panel 3, mouse, 1:2000) and C-terminal domains of PfUT (panels 2 and 4, rabbit, 1:3000). Panel 1 shows a late ring stage parasite, the other panels show trophozoites. GFP fluorescence was detected, by confocal fluorescence microscopy, in parasites expressing episomally a PfCRT/GFP fusion protein. The different antisera raised against PfUT showed comparable results. Bar, 2 mm. Immunofluorescence microscopy partially co-localized PfUT with the ER marker BiP and the Golgi marker ERD2, but not with PfCRT.
