Evi-1 interacts with CtBP1 in vitro.
(A) Construction of GST fusion proteins of the wild-type or mutant forms of Evi-1 (544-607). (B) GST pull-down experiments. Here, 5 μg bacterially expressed GST alone (lane 1), GST-DL/DL (lane 2), GST-AS/DL (lane 3), GST-DL/AS (lane 4), and GST-AS/AS (lane 5) were incubated with in vitro–translated [35S]methionine-labeled CtBP1. After extensive washing, the samples were subjected to SDS-PAGE followed by autoradiography (top). Half of the input of in vitro–translated [35S]methionine-labeled CtBP was presented in lane 6. Positions of size markers (in kilodaltons) are indicated on the left. Coomassie stains of GST-fusion proteins are indicated (bottom).
