  • Function

    Adapter protein that provides a critical link between cell surface growth factor receptors and the Ras signaling pathway.
    Isoform GRB3-3 does not bind to phosphorylated epidermal growth factor receptor (EGFR) but inhibits EGF-induced transactivation of a RAS-responsive element. Isoform GRB3-3 acts as a dominant negative protein over GRB2 and by suppressing proliferative signals, may trigger active programmed cell death.
  • Sequence similarities

    Belongs to the GRB2/sem-5/DRK family.
    Contains 1 SH2 domain.
    Contains 2 SH3 domains.
  • Domain

    The SH3 domains mediate interaction with RALGPS1 and SHB.
  • Cellular localization

    Golgi apparatus.

  • IHC image of GRB2 staining in a section of formalin-fixed paraffin-embedded normal human colon tissue*, performed on a Leica BOND. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab201865, 1/50 dilution, for 15 mins at room temperature. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset negative control image is taken from an identical assay without primary antibody.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 25 kDa
    Observed band size: 26 kDa
    why is the actual band size different from the predicted?

    Exposure time: 30 seconds

    This blot was produced using a 4-12% Bis-tris gel under the MES buffer system. The gel was run at 200V for 35 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab201865 overnight at 4°C. Antibody binding was visualised using ECL development solution ab133406.
