PF3D7_1323500 PEXEL protease plasmepsin V

PfJ2 is an essential, ER-resident protein. A) PfJ2apt parasites were fixed and stained with DAPI (blue) and with antibodies against HA (green) and the ER marker PfPMV (red). Ring (R), Trophozoite (T), and Schizont (S) stage parasites are shown. Z-stack Images were deconvoluted and shown as a single, maximum intensity projection. Scale bar represents 5 μm. Co-localization between PfJ2 and the ER-marker Plasmepsin V (PfPMV) revealed that PfJ2 is in fact an ER-resident protein, consistent with the localization of episomally over expressed PfJ2 previously reported.
