<i>Abp1</i> knock-out leads to impaired larval migration.

<p>(<b>A</b>) Genomic scheme of <i>abp1</i> (<i>CG10083</i>) locus 3 L 70B2 with PBac insertion WH f05024, of <i>abp1</i> knock-out (<i>abp1</i>^KO) <i>flies</i> generated by FRT-mediated recombination of PBac insertions, of the deficiency Df(3 L) and of the revertant <i>abp1</i>^WH-rev. Shown are exons with translated (red) and untranslated regions (grey). (<b>B–D</b>) Summarized presentation of migration tracks with centered common start points (bars, 5 mm) of <i>wt</i> (<b>B</b>), <i>abp1</i>^KO/Df(3 L) (<b>C</b>) and <i>abp1</i>^WH-rev/Df(3 L) (<b>D</b>). (<b>E</b>) Mean velocities of larval migration (n = 17–38). Data represent mean±SEM. ** = p<0.01. One way ANOVA post Tukey.
