        Homozygous larvae show a highly significant reduction in pharyngeal movements and locomotor body wall contractions compared to controls.

        Homozygous larvae show a significant decrease in mean evoked EJC amplitude at the neuromuscular junction. The mutants show a significant increase in both the amplitude and frequency of mEJC events. Homozygous larvae show a significant impairment of endo-exo synaptic vesicle cycling (assayed by lipophilic dye imaging), with a particularly severe defect in synaptic vesicle exocytosis.
