Grb2 Protein, Human (His)
Based on 1 Customer Validation
Grb2, an adapter protein, crucially connects cell surface growth factor receptors to the Ras signaling pathway. Despite no direct binding to phosphorylated EGFR, Grb2 inhibits EGF-induced transactivation of a RAS-responsive element. It acts as a dominant negative relative to GRB2, suppressing proliferative signals and potentially initiating programmed cell death. Grb2 Protein, Human (His) is the recombinant human-derived Grb2 protein, expressed by E. coli , with C-6*His labeled tag.
- Species: Human
- Source: E. coli
-
Storage:Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Biological Activity
Grb2, an adapter protein, crucially connects cell surface growth factor receptors to the Ras signaling pathway. Despite no direct binding to phosphorylated EGFR, Grb2 inhibits EGF-induced transactivation of a RAS-responsive element. It acts as a dominant negative relative to GRB2, suppressing proliferative signals and potentially initiating programmed cell death. Grb2 Protein, Human (His) is the recombinant human-derived Grb2 protein, expressed by E. coli , with C-6*His labeled tag.
Grb2, an adapter protein, plays a pivotal role in establishing a crucial connection between cell surface growth factor receptors and the Ras signaling pathway. Despite its lack of direct binding to phosphorylated epidermal growth factor receptor (EGFR), Grb2 exerts an inhibitory effect on EGF-induced transactivation of a RAS-responsive element. Notably, Grb2 functions as a dominant negative protein relative to GRB2, suppressing proliferative signals and potentially instigating active programmed cell death.
1.Immobilized Human GRB2 at 2 μg/mL (100 μL/well) can bind Anti-GRB2 Antibody. The ED50 for this effect is 93.39 ng/mL.
2.Measured in a cell proliferation assay using A549 cells. The ED50 for this effect is ≤33.3 ng/mL, corresponding to a specific activity is 3.003×104 units/mg
