From: Loss of full length CtBP1 expression enhances the invasive potential of human melanoma
CtBP1splice does not interact with TCF4 and Snail. Co-immunoprecipitation were performed using protein lysates of Mel Im Mock 1 control transfected cells and the CtBP1#3 cell clones and were incubated with TCF4-antibody (A) or Snail-antibody (B). Western blotting with CtBP1-antibody confirmed binding of full length CtBP1 to TCF4 (A) and Snail (B), respectively, whereas CtBP1splice could not interact with these proteins.
