cindr interacts with cpb and cpa. (A) GMR>cindr-IR² retina probed for DE-Cad (green, A′) and Rst (red, A″). (B) cpb^F-19/GMR>cindr-IR². Mispatterning was strongly enhanced. (C) cpb^bnd1/GMR>cindr-IR². (D) In wild-type retinae, Cpb (green) and Cindr (blue) colocalized. DE-Cad is shown in red. (E) Western analysis of final eluants of coimmunopreciptations from embryos expressing cindr-PC^TAP or TAP only probed with α-Cindr (top) or α-Cpb (bottom). (F–H) cindr-IR² was strongly enhanced in trans to cpa heterozygotes or when cpa was overexpressed. (F) cpa^scrd1/GMR>cindr-IR². (G) cpa^69E/GMR>cindr-IR². (H) GMR>cindr-IR², cpa. All tissue was dissected at 41 h APF; DE-Cad is only shown in C, F, G, and H. Bars, 10 μm.
