PF3D7_1133400 apical membrane antigen 1

C1 and C2 do not affect expression, trafficking or maturation of PfSUB1. (A) IFA of mature wt 3D7 parasites following treatment for 6 h with DMSO only (1% v/v) or 2.5 mM C1, probed with the anti-PfSUB1 mAb NIMP.M7 or a rabbit anti-PfAMA1 serum. The PfPKG inhibitor had no effect on localisation or expression of PfSUB1 or PfAMA1. For clarity, the anti-PfSUB1 and anti-PfAMA1 signals are shown merged in addition to a final merge with the DAPI signal. Similar results were obtained following treatment with 1.5 mM C2 (not shown). Note that treatment with the PKG inhibitors also had no effect on schizont replication as determined by counts of the average number of nuclei per schizont (data not shown, but compare DAPI staining of untreated and treated schizonts).
