Testing Data
(HTRF assay for EGFR (672-1210, L858R) protein activity 1 micro;M TK substrate was incubated with different concentrations of EGFR (672-1210, L858R) protein in a 10 ul reaction system containing 1×Enzymatic Buffer, 5 mM MgCl2, 1 mM DTT, 5 nM SEB and 100 uM ATP for 1 hour. Then 10 ul detection reagents containing TK antibody and SA-XL665 (each of which was 1:100 diluted with 1× Detection Buffer) were added and incubated with the reactions for 30 min. All the operations and reactions were performed at room temperature. HTRF KinEASE TK assay was used to detect the enzymatic activity.)

Background: EGFR (Epidermal Growth Factor Receptor), also known as ERBB, mENA, ERBB1 and HER1, is the receptor for members of the EGF family and is a transmembrane glycoprotein that has tyrosine kinase activity. Receptor tyrosine kinase binding ligands of the EGF family and activating several signaling cascades to convert extracellular cues into appropriate cellular responses. Known ligands include EGF, TGFA/TGF-alpha, AREG, epigen/EPGN, BTC/betacellulin, epiregulin/EREG and HBEGF/heparin-binding EGF. Ligand binding triggers receptor homoand/or heterodimerization and autophosphorylation on key cytoplasmic residues. The phosphorylated receptor recruits adapter proteins like GRB2 which in turn activates complex downstream signaling cascades, including at least 4 major downstream signaling cascades: the RAS-RAF-MEK-ERK, PI3 kinase-AKT, PLCgamma-PKC and STATs modules, leading to cell proliferation. EGFR is widely recognized for its importance in cancer. Amplification and mutations of this gene have been shown to be driving events in many cancer types. Its role in non-small cell lung cancer, glioblastoma and basal-like breast cancers has spurred many research and drug development efforts. In particular, EGFR mutation analysis of NSCLC (non-small cell lung cancer) is now routine in standard clinical practice, and tyrosine kinase inhibitors (TKIs) targeting EGFR-activating mutations are the most widely used targeted therapy, most notably gefitinib and erlotinib. Patients carrying a point mutation in exon 21 (L858R) or a deletion in exon 19, which account for approximately 90% of EGFR-activating mutations, have significant survival benefit when treated with EGFR-TKI.
NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene is a transmembrane glycoprotein that is a member of the protein kinase superfamily. This protein is a receptor for members of the epidermal growth factor family. EGFR is a cell surface protein that binds to epidermal growth factor. Binding of the protein to a ligand induces receptor dimerization and tyrosine autophosphorylation and leads to cell proliferation. Mutations in this gene are associated with lung cancer. Multiple alternatively spliced transcript variants that encode different protein isoforms have been found for this gene. [provided by RefSeq, Jul 2010]
Uniprot Description
EGFR: a receptor tyrosine kinase. This is a receptor for epidermal growth factor (EGF) and related growth factors including TGF-alpha, amphiregulin, betacellulin, heparin-binding EGF-like growth factor, GP30, and vaccinia virus growth factor. EGFR is involved in the control of cell growth and differentiation. It is a single-pass transmembrane tyrosine kinase. Ligand binding to this receptor results in receptor dimerization, autophosphorylation (in trans), activation of various downstream signaling molecules and lysosomal degradation. It can be phosphorylated and activated by Src. Activated EGFR binds the SH2 domain of phospholipase C-gamma (PLC-gamma), activating PLC-gamma-mediated downstream signaling. Phosphorylated EGFR binds Cbl, leading to its ubiquitination and degradation. Grb2 and SHC bind to phospho-EGFR and are involved in the activation of MAP kinase signaling pathways. Phosphorylation on Ser and Thr residues is thought to represent a mechanism for attenuation of EGFR kinase activity. EGFR is overexpressed in breast, head and neck cancers, correlating with poor survival. Activating somatic mutations are seen in lung cancer, corresponding to the minority of patients with strong responses to the EGFR inhibitor Iressa (gefitinib). Mutations and amplifications are also seen in glioblastoma, and upregulation is seen in colon cancer and neoplasms. In xenografts, inhibitors synergize with cytotoxic drugs in the inhibition of many tumor types. Inhibitors include: Iressa/ZD1839, Erbitux, Tarceva, and lapatinib. Four alternatively spliced isoforms have been described.

Product Notes
The EGFR egfr (Catalog #AAA389252) is a Recombinant Protein produced from Baculovirus and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "EGFR, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
