Research Abstract

To investigate additional functions of CADM1 in the epithelial cell membrane, we adopted a proteomic approach and identified Csk-binding protein (Cbp), which suppress c-Src mediated transformation and tumorigenesis. We found that CADM1 formed a protein complex with Cbp and c-Src in lipid raft fractions, and suggested to promote c-Src inactivation in a Cbp-dependent manner.
