PF3D7_0501300 skeleton-binding protein 1

Mouse DHFR fusions can clog the PVM translocon and co-block the export of other proteins. (A-E) Representative images of live P. falciparum parasites grown in the presence (+WR) or absence of WR (control) and expressing the constructs shown schematically above each panel. DIC, differential interference contrast. Arrowheads indicate faint signals at the Maurer’s clefts; arrows show mobile protrusions (note that they do not overlap in the red and the green signal due to movement between capture of the images). Size bars: 5 μm. Schematics to the right show the location of the fusion protein containing the folded WR-bound mDHFR domain (light blue circle with smaller black circle in binding pocket) and the co-expressed REX2 (red line) fused to mCherry (red circle); white box, TM; green circle, GFP; blue line, protease sensitive mutated PH domain.
