EGFR Protein, Cynomolgus (sf9, His)

EGFR Protein is a receptor tyrosine kinase that binds to ligands of the EGF family. EGFR Protein is involved in the regulation of NF-kappa-B , RAS-RAF-MEK-ERK, PI3 kinase-AKT, PLCgamma-PKC and STATs signaling pathways. EGFR Protein has calmodulin binding activity, epidermal growth factor binding activity and epidermal growth factor activating receptor activity. EGFR Protein, Cynomolgus (sf9, His) is the recombinant cynomolgus-derived EGFR protein, expressed by Sf9 insect cells , with C-His labeled tag. The total length of EGFR Protein, Cynomolgus (sf9, His) is 621 a.a., with molecular weight of ~70.1 kDa.

The EGFR protein, a receptor tyrosine kinase, binds ligands of the EGF family, including EGF, TGFA/TGF-alpha, AREG, epigen/EPGN, BTC/betacellulin, epiregulin/EREG, and HBEGF/heparin-binding EGF. This interaction initiates cascades that convert extracellular signals into cellular responses, involving receptor homo- and/or heterodimerization and autophosphorylation on key cytoplasmic residues. The phosphorylated receptor recruits adapter proteins like GRB2, activating downstream signaling cascades, including RAS-RAF-MEK-ERK, PI3 kinase-AKT, PLCgamma-PKC, and STATs modules. Additionally, EGFR may trigger the NF-kappa-B signaling cascade and directly phosphorylate proteins like RGS16, activating its GTPase activity, and potentially linking EGF receptor signaling to G protein-coupled receptor signaling. Furthermore, EGFR phosphorylates MUC1, enhancing its interaction with SRC and CTNNB1/beta-catenin. It positively regulates cell migration through interaction with CCDC88A/GIV, retaining EGFR at the cell membrane post-ligand stimulation, thereby promoting EGFR signaling and triggering cell migration. Beyond its canonical functions, EGFR contributes to enhancing learning and memory performance and plays a role in mammalian pain signaling, with isoform 2 potentially acting as an antagonist to EGF action^{[1][2][3][4][5]}.
