PF3D7_1222300 endoplasmin, putative

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.
