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:28195530, PubMed:28195038, 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 ==
		+	Understanding mechanisms of antibody synergy is important for vaccine design and antibody cocktail development. Examples of synergy between antibodies are well-documented, but the mechanisms underlying these relationships often remain poorly understood. The leading blood-stage malaria vaccine candidate, CyRPA, is essential for invasion of Plasmodium falciparum into human erythrocytes. Here we present a panel of anti-CyRPA monoclonal antibodies that strongly inhibit parasite growth in in vitro assays. Structural studies show that growth-inhibitory antibodies bind epitopes on a single face of CyRPA. We also show that pairs of non-competing inhibitory antibodies have strongly synergistic growth-inhibitory activity. These antibodies bind to neighbouring epitopes on CyRPA and form lateral, heterotypic interactions which slow antibody dissociation. We predict that such heterotypic interactions will be a feature of many immune responses. Immunogens which elicit such synergistic antibody mixtures could increase the potency of vaccine-elicited responses to provide robust and long-lived immunity against challenging disease targets.
