== Publication Abstract from PubMed ==
Plasmodium falciparum, the causative agent of malaria, employs a diverse array of surface displayed proteins to promote dissemination and establish infection in the human host. Of these, Pf3D7_0606800 is highly immunogenic and has been designated a potential top 10 candidate for inclusion in a multicomponent malarial vaccine. The role of Pf3D7_0606800 in parasite biology, however, is unknown and its characterization has been complicated by a lack of sequence identity with proteins of known structure or function. Towards elucidating Pf3D7_0606800 function, we determined its structure to a resolution of 2.35 A using selenium single wavelength anomalous dispersion. A bi-lobed architecture displays the core structural hallmarks of Venus Flytrap (VFT) proteins prompting us to re-annotate Pf3D7_0606800 as PfVFT1. Structural analysis further revealed an extended inter-lobe groove that, when interrogated by molecular docking, appears well suited to bind peptide-based ligands. Collectively, our structural characterization of the highly antigenic P. falciparum surface protein PfVFT1 provides intriguing functional insight and establishes a structural template that could prove valuable for malaria vaccine engineering studies.
