Figure legend: "(F) Example kymograph of Khc molecules (red) associating with an oskMS2-GFP mRNP (green) before and during its run. White arrowheads indicate two association events, yellow arrow indicates the onset of motility. Scale bars represent 5 µm and 1 second, respectively.(G) Frequency of Khc-mKate2 appearance on motile (white), before (motility-primed, checked) and after (dotted) the onset of motility, and non-motile (grey) oskMS2-GFP trajectories. Fractions within the bars indicate number of association events that lasted longer than a single frame over the total number of frames analysed. Indicated P values show results of pairwise Fisher's exact test. The Khc association frequency observed on RNPs before (checked) and during (dotted) their motility is not significantly different from wild-type motile RNP controls (p&gt;0.01)."

Figure legend: "(D, E) Localization of Khc-mKate2 (green) and oskar mRNA (magenta) in wild-type and Tm1gs mutant nurse cells.(F, G) Fraction of oskar mRNPs co-localizing with Khc-mKate (dark grey), EmGFP-Tm1-I (white), or both of these proteins (light grey) in the oocyte (F) or in the nurse cells (G) (max. colocalization distance is 250 nm). None of the values are significantly different from each other (one-way ANOVA, p&gt;10-3). Horizontal dashed lines indicate the expected value of observing both proteins in an oskar mRNP if the interactions are independent (see Fig EV3C and D). Significance of the observed co-localization values versus the expected values are shown.(H) Fraction of oskar mRNPs co-localizing with Khc-mKate in wild-type and Tm1gs mutant nurse cells when half or all Khc molecules are labelled (as indicated above the graph). P values of pair-wise t-tests are indicated.(I) Fraction of oskar mRNPs co-localizing with free mCherry in wild-type nurse cells used as negative control. The measured fraction (~1.6%) is significantly different from zero (one sample t-test). All other measured co-localization values are significantly different form this negative control (p&lt;0.001, one-way ANOVA).(F-I) Numbers indicate the number of particle clusters (100 oskar mRNPs in each) and the number of egg-chambers (in brackets) analysed. Error bars represent 95% confidence intervals. All values (F-I) are significantly different from zero (p&lt;10-3, one sample t-test)."

Genotypes are indicated as follows: wild-type control with solid black line (D-F), oskar RNA null with solid grey line (D, E), Tm1eg9/Tm1eg9 with dotted black line (D, F) Lines indicate mean and 95% confidence intervals. We analysed the accumulation of mKate2-Tm1-I instead of EmGFP-Tm1-I due to unexpected GFP expression from the oskar0 allele."

Figure legend: "(G) Khc accumulation around the NE. To calculate accumulation the signal intensity measured at the position of the peak observed in the wild-type control (D, arrowhead, 356±17.6 nm away from NE) was divided by the signal intensity 2 s.d. away (d, arrow, at 356+2*410 nm). P values of pairwise Mann-Whitney U tests against wild-type control or Tm1gs rescued with EmGFP-Tm1-I are indicated above the boxplots. Numbers indicate the number of nuclei and the number of egg-chambers (in brackets) analysed.(H-K) Khc accumulation around the NE of nurse cells over-expressing EmGFP-Tm1-I within Tm1eg9/Tm1eg9 (H), and oskar RNA null egg-chambers (I) expressing either the oskar 3' UTR (J) or oskar Δi(1,2,3) (K)."

Wild-type control (C) and oocytes expressing Khc RNAi and EmGFP-Tm1-I (E). Magenta indicates standard deviation of the distribution of oskar mRNA. Scale bar is 10% of total oocyte length (C).(F) Position of the oskar mRNA center of mass relative to the geometric center of the oocyte (dotted horizontal line) along the anteroposterior (AP) axis. Posterior pole is the top of the chart. P values of pairwise Mann-Whitney U tests are indicated. Numbers indicate number of oocytes analysed."
