PF3D7_1246200 actin I

Expression and localization of PfADF1 and PfAct1 in P. falciparum. IFA of merozoite invasion probed with anti-PfADF1, PfAct1, and PfRON4 during merozoite invasion. (Scale bars, 2 μm.). Free merozoites were captured mid-invasion and colabeled with rhoptry neck protein 4 (RON4), a marker of the tight junction that is the point of close apposition between host and parasite membranes during invasion, the site at which a ring of actin forms, a feature consistent with engagement of the actomyosin motor at the junction. PfADF1 retained its cytosolic localization during invasion with the exception that labeling was absent at the tight junction and its associated actin ring.
