EGFR Protein, Human (621a.a, HEK293, N-His, C-Myc)

EGFR Protein, a receptor tyrosine kinase, binds various ligands like EGF, TGFA, AREG, epigen, BTC, epiregulin, and HBEGF, initiating signaling cascades that mediate cellular responses. This involves receptor dimerization, autophosphorylation, and recruitment of adapter proteins like GRB2, activating downstream pathways such as RAS-RAF-MEK-ERK, PI3 kinase-AKT, PLCgamma-PKC, and STATs. EGFR can also trigger NF-kappa-B signaling, phosphorylate proteins like RGS16, and interact with MUC1, influencing G protein-coupled receptor signaling. Moreover, it enhances cell migration through interactions with CCDC88A, promoting EGFR signaling and triggering cell migration. Additionally, EGFR impacts learning, memory, and pain signaling. EGFR Protein, Human (621a.a, HEK293, N-His, C-Myc) is the recombinant human-derived EGFR protein, expressed by HEK293, with C-Myc, N-10*His labeled tag. The total length of EGFR Protein, Human (621a.a, HEK293, N-His, C-Myc) is 621 a.a., with molecular weight of 73.6 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, 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.
