(G) GST or GST-ALIX were incubated with in vitro translated 35S-methionine-labelled γ−tubulin or Dgrip91. The upper panel shows the autoradiography indicating interaction between GST-ALIX and radiolabelled γ-tubulin or Dgrip91. The lower panel shows the Ponceau S-stained membrane visualizing the expression of GST and GST-ALIX. The experiment was performed at least three times and a representative result is presented
