| + | Invasion of erythrocytes by Plasmodial merozoites is a composite process involving the interplay of several proteins. Among them, the Plasmodium falciparum Cysteine-Rich Protective Antigen (PfCyRPA) is a crucial component of a ternary complex, including Reticulocyte binding-like Homologous protein 5 (PfRH5) and the RH5-interacting protein (PfRipr), essential for erythrocyte invasion. Here we present the crystal structure of PfCyRPA and of its complex with the antigen-binding fragment of a parasite growth inhibitory antibody. While PfCyRPA adopts a 6-bladed beta-propeller structure with similarity to the classic sialidase fold, it possesses no sialidase activity, indicating that it fulfills a non-enzymatic function. Characterization of the epitope recognized by protective antibodies will facilitate design of peptidomimetics that focus vaccine responses on protective epitopes. Both in vitro and in vivo anti-PfCyRPA and anti-PfRH5 antibodies showed more potent parasite growth inhibitory activity in combination than on their own, supporting a combined delivery of PfCyRPA and PfRH5 in vaccines. | ||
