abstract = {Plasmodium falciparum is a human-adapted apicomplexan
parasite that causes the most dangerous form of malaria. P.
falciparum cysteine-rich protective antigen (PfCyRPA) is an
invasion complex protein essential for erythrocyte invasion.
The precise role of PfCyRPA in this process has not been
resolved. Here, we show that PfCyRPA is a lectin targeting
glycans terminating with α2-6-linked N-acetylneuraminic
acid (Neu5Ac). PfCyRPA has a >50-fold binding preference for
human, α2-6-linked Neu5Ac over non-human, α2-6-linked
N-glycolylneuraminic acid. PfCyRPA lectin sites were
predicted by molecular modeling and validated by mutagenesis
studies. Transgenic parasite lines expressing endogenous
PfCyRPA with single amino acid exchange mutants indicated
that the lectin activity of PfCyRPA has an important role in
parasite invasion. Blocking PfCyRPA lectin activity with
small molecules or with lectin-site-specific monoclonal
antibodies can inhibit blood-stage parasite multiplication.
Therefore, targeting PfCyRPA lectin activity with drugs,
immunotherapy, or a vaccine-primed immune response is a
promising strategy to prevent and treat malaria.},
