      Background InformationGab1 is a 115 kDa multiple docking protein that plays an essential role in cellular growth, transformation and apoptosis. Gab1 can be phosphorylated by multiple receptor tyrosine kinase (RTKs), including: insulin receptor (IR), platelet derived growth factor receptor beta] (PDGFR-β]), hepatocyte growth factor/scatter factor receptor (HGFR/SFR or c Met), and epidermal growth factor receptor (EGF), as well as in response to cell cell adhesion. Gab1 is tyrosine phosphorylated on at least 16 sites, some of which serve as binding sites for phosphoatidylinositol 3 kinase (PI3K), Grb2, PLC gamma 1, Nck, and SHP2. Phosphorylation of Gab1 on tyrosines 627 and 659 is critical for its binding to SHP2, and for activation of the ERK/MAPK pathway in response to EGF.

      Key Applications
      • Immunocytochemistry
      • Immunohistochemistry (Paraffin)
      • Immunoprecipitation
      • Western Blotting
      Application NotesImmunoprecipitation:
      4 μg of this lot immunoprecipitated Gab1 from 500 μg of a human A431 carcinoma cell RIPA lysate.

      10 μg/mL of a previous lot showed positive immunostaining for Gab1 in A431 cells fixed with 4% paraformaldehyde.
      Biological Information
      Immunogen31 residue peptide sequence corresponding to C-terminal residues 664-694 of Gab1 (CQKTLALKSTREAWTDGRQSTESETPAKSVK).
      ConcentrationPlease refer to the Certificate of Analysis for the lot-specific concentration.
      SpecificitySpecific for Gab1. No other known protein shares more than 10 amino acids with the immunizing sequence.

      Entrez Gene Number
      Entrez Gene SummaryThe protein encoded by this gene is a member of the IRS1-like multisubstrate docking protein family. The encoded protein is an important mediator of branching tubulogenesis and plays a central role in cellular growth response, transformation and apoptosis. Two transcript variants encoding different isoforms have been found for this gene.
