Figure 6From: Distinct and stage specific nuclear factors regulate the expression of falcipains, Plasmodium falciparum cysteine proteasesStage specific interaction of falcipain sequence elements with nuclear extracts. Nuclear extracts were prepared from synchronous cultures containing ring (R), trophozoites (T) and schizonts (S) stage parasites. Arrows indicate the DNA-protein complexes. Lower panel shows the reporter gene activity of each falcipain promoter at three developmental stages (Fig 4, for comparison purposes).Back to article page
