Pf3D7-1437000 depletion does not affect protein export: (A) Parasites were synchronized at the early ring stage, maintained in media as shown with 10 μM trimethoprim (+TMP) or an equal volume of DMSO (-TMP), or 100 nM aTc (+aTc) or an equal volume of DMSO (-aTc). Parasites were fixed 24 hours after invasion as trophozoites and stained to compare protein export in Hsp101-DD +/- TMP and 1437APT +/- aTc. Exported proteins are marked by anti-HRP2 or anti-FIKK4.2, each shown in green; the parasite cytosol is marked by anti-aldolase shown in red; parasite nucleus marked by DAPI in blue. Experiment was performed three times; representative images shown. Scale bars represent 5 μm.
