Sub-cellular localization of P. falciparum DRM-associated proteins. Immunofluorescence studies were performed on paraformaldehyde-fixed P.falciparum trophozoite-iRBCs using mouse immune sera raised against the DRM-associated proteins PFJ130, (PF10_0130) PFN201, (PF14_0201 surface protein) PFB985c, (PFB0985c) Pfmc-2TM Maurer's cleft two transmembrane protein; PFL1070c, endoplasmin homolog precursor) PFK351 (PF11_0351) HSP70. Immune sera specific for PfBip and PfEXP1-were used for co-labeling, as indicated. Mitochondria labeling was performed with MitoTracker® probe. Parasite nuclei were stained with Hoechst 33342. Microscopic observations were made on an apotome-equipped Axio Imager 2 (Carl Ziess, Jena) with a 100× apochromat objective and DIC. The differential interference contrast (DIC), merged and overlay images are presented. Bar size: 5 µm. PfK351overlays mitotracker thus localized to parasite mitochondrion. PfL1070 colocalizes with the ER-resident marker PfBiP. PfK55, a conserved hypothetical protein with unknown function, contains a SP and a ER retention signal (KDEL), but due to poor IFA, the exact subcellular localization of this protein remained elusive.Yam XY, Birago C, Fratini F, Di Girolamo F, Raggi C, Sargiacomo M, Bachi A, Berry L, Fall G, Curra C, Pizzi E, Braun-Breton C, Ponzi M.
