      Alternate Names
      • Reticulocyte-binding protein 2
      Background InformationReticulocyte-binding protein 2 (UniProt: Q00799; also known as PvRBP2) is encoded by the RBP-2 (also known as RBP2) gene in Plasmodium species. PvRBP2b is an alpha-helical protein, comprising 10 alpha-helices and two very short antiparallel beta-sheets, each comprising two beta-strands. It plays a critical role in reticulocyte recognition and invasion by Plasmodium vivax. It is synthesized with a signal peptide (aa 1-21), a large extracellular domain (aa 22-2805), a short transmembrane domain (aa 2806-2826), and a cytoplasmic tail (aa 2827-2867). Plasmodium vivax is shown to preferentially invade reticulocytes that express high levels of transferrin receptor 1 (TfR1). PvRBP2b is expressed during the late-stage of Plasmodium vivax and its binding has been shown to directly correlate with the levels of TfR1 on reticulocyte surface. Treatment of reticulocytes with trypsin or chymotrypsin can cleave TfR1 from reticulocyte surface and prevent PvRBP2b binding. Clone 3E9 is shown to inhibit reticulocyte binding and block the entry of Plasmodium vivax into reticulocytes. This antibody binds to the side of the N-terminal domain of PvRBP2b to a region localized between helices alpha 4, 5 and 6. (Ref.: Gruszczyk, J., et al. (2018). Science 359(6371); 48-55; Gruszczyk, J., et al. (2018). Nature. 559(7712); 135-139).
