Resumen
Erythrocyte binding ligand 1 (EBL-1) is a member of the ebl multigene family involved in Plasmodium falciparum invasion of erythrocytes. We found that five EBL-1 high-activity binding peptides (HABPs) bound specifically to erythrocytes: 29895 (41HKKKSGELNNNKSGILRSTY60), 29903 (201LYECGKKIKEMKWICTDNQF220), 29923 ( 601CNAILGSYADIGDIVRGLDV620), 29924( 621WRDINTNKLSEKFQKIFMGGY640), and 30018 ( 2481LEDIINLSKKKKKSINDTSFY2500). We also show that binding was saturable, not sialic acid-dependent, and that all peptides specifically bound to a 36-kDa protein on the erythrocyte membrane. The five HABPs inhibited in vitro merozoite invasion depending on the peptide concentration used, suggesting their possible role in the invasion process.
