PF3D7_0731500 erythrocyte binding antigen-175

PfMyoB-GFP is located at the apical pole of the merozoite. Indirect immunofluorescence of PfMyoB-GFP (green) with various merozoite organelle markers (red), using antisera to i) EBA175 (microneme marker), ii) RAP1 (rhoptry bulb), iii) RON4 (rhoptry neck) and iv) α-tubulin. Samples were counterstained with DAPI (blue). The merged images are also shown. Rows i-iii show individual schizonts, row iv shows an individual merozoite. Scale bar: 2 μM. Antibodies to GFP produced a compact discrete dot pattern of fluorescence located at the very apical end of the MyoB-GFP parasites, near to the localisation of the apical markers EBA175, RON4, and RAP1. However, whilst in some cases the fluorescent signal partially overlapped with these markers, MyoB appeared to be in a distinct location within the cell, anterior to the microneme marker, the rhoptry bulb, and even to the rhoptry neck.
