摘要: Summary Invasion of the merozoite form Plasmodium falciparum into human erythrocytes involves multiple receptor‐ligand interactions. The EBA175 protein P. has been shown to be ligand that binds a sialic acid-dependent site on glycophorin A. We have identified novel ligand, termed erythrocyte-binding antigen 140 (EBA140), shares structural features and homology with EBA175. Subcellular localization EBA140 suggests it is located in micronemes, same as receptor surface erythrocytes. Binding this erythrocyte sensitive neuraminidase resistant trypsin, proteinase K pronase. proteaseresistant properties not A or C. Additionally, analysis mutant from humans does bind B. Interestingly, we parasite line lacks eba140 gene, suggesting essential for vitro invasion. These results suggest may involved invasion using
