Cindr interacts with specific adhesion receptors. Tagged (A) hbs, (B) rst, (C) sns, or (D) kirre were expressed in embryos using the da-GAL4 driver and precipitated with (+) or without (−) the anti-Cindr antibody. Western blot analyses were performed with antibodies to the protein tags. (E) fas2 or (F) DE-Cad were expressed in embryos and similarly precipitated with anti-Cindr; blots were probed with antibodies to Fas2 and DE-Cad, respectively. For C and D, 80% of the eluant of each co-immunoprecipitation reaction was analysed; 50% of each reaction was loaded in all other Western analyses shown.
