  • Title: Receptor and ligand domains for invasion of erythrocytes by Plasmodium falciparum.
    Author: Sim BK, Chitnis CE, Wasniowska K, Hadley TJ, Miller LH.
    Journal: Science; 1994 Jun 24; 264(5167):1941-4. PubMed ID: 8009226.
    Abstract:
    A 175-kilodalton erythrocyte binding protein, EBA-175, of the parasite Plasmodium falciparum mediates the invasion of erythrocytes. The erythrocyte receptor for EBA-175 is dependent on sialic acid. The domain of EBA-175 that binds erythrocytes was identified as region II with the use of truncated portions of EBA-175 expressed on COS cells. Region II, which contains a cysteine-rich motif, and native EBA-175 bind specifically to glycophorin A, but not to glycophorin B, on the erythrocyte membrane. Erythrocyte recognition of EBA-175 requires both sialic acid and the peptide backbone of glycophorin A. The identification of both the receptor and ligand domains may suggest rational designs for receptor blockade and vaccines.
