PF3D7_1335400 reticulocyte binding protein 2 homologue a

Immuno-electron microscopy localisation of PfRh2a and PfRh2b during merozoite invasion of human erythrocytes. (A) The PfRh2a/2b proteins localise to the rhoptry neck and moving junction of merozoites. Transmission electron micrographs of pre- and mid-invasion merozoites showing PfRh2a/b-specific immunogold labelling (white arrows). At the pre-invasion stage, PfRh2a/b localises to the rhoptry neck (inset), while during mid-invasion, PfRh2a/b localises both to the moving junction and to the merozoite surface within the invasion pit. Scale bar = 0.2 mm. (B) The EBA-175 protein localises to the micronemes and apical tip of merozoites. At the pre-invasion stage, EBA-175 is located within micronemes (inset), while during mid-invasion, EBA-175 can be located either at the apical tip or within the invasion pit. Scale bar = 0.2 mm.
