Subcellular localization of rSURFIN4.1 Full (3D7A) in P. falciparum-infected red blood cells. Representative fluorescence images showing the localization of rSURFIN4.1 The differential interference contrast (DIC), fluorescence image with mouse anti-Ty antibody (α-Ty, reacts with Surfin4.1), Maurer’s clefts location with rabbit anti-SBP1 antibody (α-SBP1), and merged image with nucleus staining with DAPI (Merge) are shown. rSURFIN4.1 exhibits a dotted fluorescence pattern within the red blood cell cytosol, co-localized with PfSBP1.

Localization of SURFIN4.1 by immunofluorescence staining on air-dried monolayers from 3D7S8 parasite strain. Air dried monolayers probed with rabbit anti-SURFIN4.1 on 3D7S8 pRBC. Propidium iodide (red) was used to stain the parasite nucleus and SURFIN4.1 and SURFIN4.2 (which is encoded by the same gene) proteins were stained green using anti-rabbit Alexa 488. SURFIN4.1 localizes within the parasitophorous vacuole (PV) and is observed from approximately 30 hrs post invasion. SURFIN4.1 was observed as a green dot above the food vacuole (a), at 30–35 hrs parasite stages. The protein was spread around the parasitophorous vacuole (PV) at 35–40 hrs parasite stages and in the mature schizont (44–48 hrs) SURFIN4.1 was observed between the dividing merozoites. During the trophozoite and early schizont stages SURFIN4.2 shows a similar pattern of staining as SURFIN4.1.Mphande FA, Ribacke U, Kaneko O, Kironde F, Winter G, Wahlgren M.

Regions of SURFIN4.1 required for the export to the Maurer's clefts. (A) Schematic drawings of the recombinant proteins, rSURFIN4.1 NCVT (NCVT), rSURFIN4.1 NCV (NCV), rSURFIN4.1 NCT (NCT), and rSURFIN4.1 N-T (N-T) are depicted in the left panels. The right panels show co-localization of a series of recombinant SURFIN4.1 detected with anti-Ty antibody (α-Ty) and counter-staining with PfSBP1 (α-SBP1) by IFA. The differential interference contrast (DIC) and merged images with nucleus stained with DAPI (Merge) are shown. (+) or (−) indicates positive or negative detection of the signals in the iRBC cytosol, respectively.
