Summary[edit]

Description
English: Flagellar beating and lateral crest seal (wild type, alpha2-annexin dominant negative strain, anti-PF16 morpholino knockdown), TIRFM movie. Movie A shows surface contacts made by a trophozoite during attachment to a glass substrate. Note the sigmoidal ventral flagellar beat and the continuous seal made by the lateral crest of the ventral disc. Movie B is an example of the dominant negative alpha2-annexin::GFP (D122A, D275A), exhibiting a decreased ventral flagellar beat amplitude, and Movie C is an example of the PF16 knockdown exhibiting normal cell movement but a decreased flagellar beat frequency. Movies B and C show that cells form surface contacts similar to wild type, including that of the lateral crest, despite disruption of ventral flagellar function.
