Loss of PfTRiC-θ does not alter export of PfSBP1 or PfREX1. IFA of acetone-fixed ring-stage infected RBC. i) PfTRiC-θ ± 0.5 μM aTc (anhydrotetracycline), ii) HSP101 ± 10 μM trimethoprim (TMP). DAPI stains the parasite nuclei and PfEXP2 delineates the parasite parasitophorous vacuole compartment. Scale bars = 5 μm. Data are representative of two independent assays. DIC = differential interference contrast. Loss of the PfTRiC complex does not alter export of PfSBP1 or PfREX1 (i). This was in contrast to the block in export of PfSBP1 and PfREX1 observed upon TMP removal in the previously characterized PfHSP101-DDD line (ii).
