Growth factor receptor-bound protein 2 (GRB2) is an adaptor protein. It links the epidermal growth factor receptor tyrosine kinase to the activation of Ras and its downstream kinases. GRB2 contains an SH2 domain which binds tyrosine phosphorylated sequences and 2 SH3 domains which direct complex formation of proline-rich sequences. GRB2 is involved in signal transduction.
