  • PubMed Abstract: 

    P25 and P28 proteins are essential for Plasmodium parasites to infect mosquitoes and are leading candidates for a transmission-blocking malaria vaccine. The Plasmodium vivax P25 is a triangular prism that could tile the parasite surface. The residues forming the triangle are conserved in P25 and P28 from all Plasmodium species. A cocrystal structure shows that a transmission-blocking antibody uses only its heavy chain to bind Pvs25 at a vertex of the triangle.
