[https://www.uniprot.org/uniprot/CYRPA_PLAF7 CYRPA_PLAF7] Essential for the invasion of host erythrocytes by blood stage merozoites (PubMed:22593616, PubMed:25583518, PubMed:27374406, PubMed:28195038, PubMed:28195530). Required for the assembly of the PfRH5 adhesion complex (or invasion complex) composed of CyRPA, RH5 and RIPR at the interface between the merozoite and the host erythrocyte membranes (PubMed:25583518, PubMed:28186186, PubMed:28195038, PubMed:28195530, PubMed:30542156). This facilitates the binding of RH5 to host receptor BSG/basigin, which leads to the establishment of a tight junction between the merozoite and host erythrocyte membranes and allows Ca(2+) release into the erythrocyte (PubMed:27374406, PubMed:28186186, PubMed:30542156).<ref>PMID:22593616</ref> <ref>PMID:25583518</ref> <ref>PMID:27374406</ref> <ref>PMID:28186186</ref> <ref>PMID:28195038</ref> <ref>PMID:28195530</ref> <ref>PMID:30542156</ref>

== Publication Abstract from PubMed ==
 +
Plasmodium falciparum causes malaria in humans with over 450,000 deaths annually. The asexual blood stage involves invasion of erythrocytes by merozoites, in which they grow and divide to release daughter merozoites, which in turn invade new erythrocytes perpetuating the cycle responsible for malaria. A key step in merozoite invasion is the essential binding of PfRh5/CyRPA/PfRipr complex to basigin, a step linked to formation of a pore between merozoites and erythrocytes. We show CyRPA interacts directly with PfRh5. An invasion inhibitory monoclonal antibody to CyRPA blocks binding of CyRPA to PfRh5 and complex formation thus illuminating the molecular mechanism for inhibition of parasite growth. We determined the crystal structures of CyRPA alone and in complex with antibody Fab fragment. CyRPA has a six-bladed beta-propeller fold, and we identify the region that interacts with PfRh5. This functionally conserved epitope is a potential target for vaccines against P. falciparum.
