| We have shown that the substrate trapping mutant form of DEP 1 interacted with a small subset of tyrosine phosphorylated proteins from lysates of the human breast tumor cell lines MDA MB 231 , T 47D , and T 47D / Met and have identified the hepatocyte growth factor / scatter factor receptor Met , the adapter protein Gab 1 , and the junctional component p 120 catenin as potential substrates . ^^^ |
