Following the publication of this article  concerns were raised regarding similarities between the ey-GAL4 results presented in Fig 2D and 2E. Similarly, concerns were raised regarding similarities between the GMR-GAL4 results presented in S3E and S3F Fig. The corresponding author explained that for each pair of figure panels (Fig 2D and 2E; S3E and S3F Fig) the results were obtained in the same blot experiment. Lanes from the same original blot image were spliced together to present pertinent results in each panel; the control data were reused in Fig 2D and 2E and in S3E and S3F Fig. There was also an error in the final sentence of the S3 Fig legend, which referenced panels C and D instead of panels E and F as reporting the phosphorylation data. The updated figure legends below clarify the duplicate use of the control results and address the referencing errors. S1 File presents the original blots underlying results shown in Fig 2D and 2E and S3E and S3F Fig. (Figure Presented).
