    Protocol

    Specificity / Sensitivity

    GRB2 Antibody detects endogenous levels of total GRB2 protein.

    Species Reactivity:

    Human, Mouse, Rat, Hamster, Monkey, Bovine

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to carboxy-terminal residues of human GRB2. Antibodies are purified by protein A and peptide affinity chromatography.

    Background

    Growth factor receptor-binding protein 2 (GRB2) is an adaptor protein that is involved in RTK signal transduction. The SH2 domain of GRB2 binds to tyrosine phosphorylated proteins, such as EGFR, IRS-1, Shc, and Gab1 (1). The SH3 domain of GRB2 associates with SOS, which stimulates the Ras GTP-binding activity, leading to the activation of the MAP kinase and other signaling pathways. Phosphorylation of GRB2 at Tyr209 by Bcr-Abl and EGFR abolishes its association with SOS and negatively regulates downstream signaling (2).
