Recombinant Human GRB2 Protein

Product Name: Recombinant Human GRB2 Protein
Catalog #:  hRP-1381
Manufacture:  LD Biopharma, Inc.

The protein encoded by human Growth factor receptor-bound protein 2 (GRB2) gene binds the epidermal growth factor receptor and contains one SH2 domain and two SH3 domains. Its two SH3 domains direct complex formation with proline-rich regions of other proteins, and its SH2 domain binds tyrosine phosphorylated sequences. This gene is similar to the Sem5 gene of C.elegans, which is involved in the signal transduction pathway. Recent data indicated that GRB2 plays a role as modifier of b-catenin-dependent Wnt signaling by interacting with Dvl2 and acts downstream of FAK to amplify b-catenin-dependent transcription through a mechanism involving Rac1, Jnk and c-jun.

Full-length human GRB2 cDNA (2 – 217 aa) was constructed with codon optimization and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal. This protein is expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
