PF3D7_0202000 knob-associated histidine-rich protein

Inducible knockdown of REX1 using the glmS ribozyme system decreases the number of Maurer's cleft puncta. B,D. Immunofluorescence

microscopy of paraformaldehyde-fixed infected RBCs probed with Maurer’s cleft marker anti-

MAHRP1 (green) and anti-HA or anti-KAHRP (red). Nuclei are stained with DAPI (blue). Scale bar = 3 μm. C. Quantitation of numbers of Maurer’s clefts produced by REX1_KD transfectants in the presence and absence of 2.5 mM GlcN. The mean number of Maurer’s clefts produced per singly nucleated infected RBC was determined by counting SBP1-labelled puncta in at least 10 cells. Error bars = S.D. These puncta correspond to individual Maurer’s cleft cisternae that have a distributed organization within the RBC cytoplasm
