| Description |
The recombinant human epidermal growth factor receptor (EGFR) is expressed from mammalian cells and fused with a 10xHis-tag at the N-terminus and a Myc-tag at the C-terminus. It contains amino acid residues 25-645 of the human EGFR protein. Its protein length covers the extracellular domain of the EGFR protein. The purity of this EGFR protein is greater than 90% determined by SDS-PAGE. The endotoxin content of recombinant EGFR protein is less than 1.0 EU/ug measured by the LAL method. Importantly, it has been validated to be active. In the functional ELISA, this EGFR protein can bind to the anti-EGFR antibody and Cetuximab, respectively. The EC50 is 2.867-3.571 ng/ml and 0.6919-1.047 ng/ml, respectively. In the LSPR assay, the human EGF captured on the COOH chip can bind to this EGFR protein with an affinity constant of 11.9 nM. And it is in stock now. EGFR is a receptor tyrosine kinase that phosphorylates numerous intracellular substrates that activate pathways resulting in cell growth, DNA synthesis, and expression of oncogenes such as Fos and Jun. It regulates epithelial tissue development and homeostasis under physiological conditions but drives tumorigenesis in pathological settings, especially in lung and breast cancer. EGFR has been identified to be one of the most frequently changed oncogenes in solid tumors. |

| Function |
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 homo- and/or heterodimerization and autophosphorylation on key cytoplasmic residues. The phosphorylated receptor recruits adapter proteins like GRB2 which in turn activates complex downstream signaling cascades. Activates at least 4 major downstream signaling cascades including the RAS-RAF-MEK-ERK, PI3 kinase-AKT, PLCgamma-PKC and STATs modules. May also activate the NF-kappa-B signaling cascade. Also directly phosphorylates other proteins like RGS16, activating its GTPase activity and probably coupling the EGF receptor signaling to the G protein-coupled receptor signaling. Also phosphorylates MUC1 and increases its interaction with SRC and CTNNB1/beta-catenin. Positively regulates cell migration via interaction with CCDC88A/GIV which retains EGFR at the cell membrane following ligand stimulation, promoting EGFR signaling which triggers cell migration. Plays a role in enhancing learning and memory performance.; Isoform 2 may act as an antagonist of EGF action.; (Microbial infection) Acts as a receptor for hepatitis C virus (HCV) in hepatocytes and facilitates its cell entry. Mediates HCV entry by promoting the formation of the CD81-CLDN1 receptor complexes that are essential for HCV entry and by enhancing membrane fusion of cells expressing HCV envelope glycoproteins.
