PF3D7_1022700 phospholipid scramblase, plscr

Immunofluorescence analysis of PfPLSCR-HA expressing parasites. The upper panel depicts two ring-stage parasites and co-labelling with anti-SPP (signal peptide peptidase) antibodies as an ER marker. Anti-EXP1 (exported protein 1) delineates the PVM surrounding three trophozoites in a multiply infected red blood cell. Lower two panels show deconvolved co-labelling with antibodies against MSP1 (merozoite surface protein 1) in late blood stage parasites. PfPLSCR-HA co-localises with MSP1 at the plasma membrane in late schizonts. Parasite nuclei are stained with DAPI (blue). Scale bar = 1 mM. Immunofluorescence analysis revealed the localisation of the epitope-tagged protein to the periphery of individual merozoites in late schizonts as suggested by co-localisation with the merozoite surface protein MSP1. The protein also localised to a perinuclear region in the early ring stages as evident by partial co-localisation with the ER-resident protein signal peptide peptidase, and redistributed to the cytoplasm and vesicular foci in early trophozoite and schizont stages
