GRB2 produced in E.Coli is a single, non-glycosylated polypeptide chain containing 237 amino acids (1-217 a.a.) and having a molecular mass of 27 kDa.GRB2 is expressed with a 20 amino acid His tag at N-Terminus andpurified by proprietary chromatographic techniques.
GRB2 is widely expressed and binds the EGFR and contains one SH2 domain and two SH3 domains which form a complex formation with proline-rich regions of other proteins, and its SH2 domain binds tyrosine phosphorylated sequences. GRB2 is related to the Sem5 gene of C.elegans, which is takes part in the signal transduction pathway. GRB2 is an adaptor protein that provides an important link between cell surface growth factor receptors and the Ras signaling pathway. Inhibition of GRB2 activity damages developmental processes in a variety of organisms and blocks transformation and proliferation of different cell types.
