PF3D7_1116000 rhoptry neck protein 4

PFF0645c is released from the rhoptries only after completion of merozoite invasion. (A) IEM of PFF0645c-HA merozoites pre and post-erythrocyte invasion labeled with immunogold anti-HA (white arrows). Scale bar = 0.2 mm. (B) Widefield 3D imaging of PFF0645c-HA merozoites labeled with anti-HA, anti-PfRON4 and DAPI showing early, mid and late invasion events. Scale bar = 5 mm. 3D reconstruction with 0.2 mm grid intervals. (C) Widefield 3D imaging of PFF0645c-HA early rings (,10 min post-invasion) labeled with anti-HA, anti-PfRON4 (,PVM) anti-RAP1 (PV) or anti-MSP1 (plasma membrane) and DAPI. Scale bar = 5 mm. 3D reconstruction with 0.2 mm grid intervals.
