(a,b) dUTX directly interacts with ecdysone receptor (EcR/Usp). (a) GST and GST-dUTX–NR containing the nuclear hormone domain were used in pull-down experiments with 35S-labelled EcR and Usp in the presence of ethanol control (−) or 10 μM ecdysone (+). The GST input proteins are shown in Coomassie Brilliant blue-stained gel, GST is labelled with arrow head and dUTX–NR with an asterisk. The EcR and Usp inputs are shown labelled with arrows. (b) Immunoprecipitation (IP) of EcR and dUTX in SL2 cells. Cells were transfected with HA-dUTX and the cell lysates were immunoprecipitated using anti-HA or a control IgG isotype antibody. The immunoprecipitates were analysed by western blotting using the anti-EcR and anti-HA antibodies. (c) Colocalization of dUTX and EcR on salivary gland polytene chromosomes. Immunostaining of salivary glands polytene chromosome prepared from third instar larvae expressing FLAG-dUTX with dUTX (green) and EcR (red), with Hoechst-stained DNA (blue). Arrows indicate examples of colocalized bands. No signal was detected when immunostaining with secondary antibody only. Scale bar represent 5 μm.
