The destruction of erythrocytes is one of the most frequently observed causes of severe malarial anemia. Recently, we showed that tagging normal erythrocytes and cells of erythroid precursors with rhoptry-derived proteins can trigger their destruction. In the present study, we used rhoptry-associated protein (RAP)-1 and RAP-3 gene-disruption mutant Plasmodium falciparum parasites and showed that 2 members of a rhoptry protein complex, RAP-1 and RAP-2, bind to the surface of normal erythrocytes. Surface iodination experiments showed that RAP-1 but not RAP-3 mutant parasites lose their capacity to tag erythrocytes. This work opens new doors into the investigation of the molecular mechanism of anemia in patients with malaria.
