PF3D7_0202000 knob-associated histidine-rich protein

Targeted gene disruption of PfPAP changes the filterability of the infected RBCs but not the expression or localization of KAHRP, REX1, and PfEMP-3. B). Immunofluorescence using anti-KAHRP, REX1, and PfEMP-3 antibodies on 3D7 and 3D7_PAP KO show no difference in the location of these proteins. C). Electron microscopy of 3D7_PAP-KO showing electron dense structures at the surface of the infected erythrocyte indicative of the presence of knobs. Bars are 5 mm.
