In our present study, we show for the first time that SHC-binging protein 1 (SHCBP1), a unique protein specifically bound to the SHC1 SH2 domain and previously reported to disassociate from SHC adaptor protein 1 (SHC1) in response to EGF stimulation, mediates EGF-induced activation of β-catenin signaling in NSCLC cells. Here, SHC1 is linked to non-small cell lung carcinoma.
