APC Anti-EGFR antibody [E235]

Target data

The protein expressed by the EGFR gene functions as a receptor tyrosine kinase, binding with ligands from the EGF family to activate several signaling cascades that translate extracellular signals into cellular responses. Known ligands include EGF, TGFA/TGF-alpha, AREG, epigen, BTC/betacellulin, epiregulin, and HBEGF. Ligand binding triggers receptor dimerization and autophosphorylation, recruiting adapter proteins like GRB2 and activating complex downstream signaling pathways such as RAS-RAF-MEK-ERK, PI3 kinase-AKT, PLCgamma-PKC, and STATs, and possibly the NF-kappa-B cascade. EGFR also directly phosphorylates proteins like RGS16 and MUC1, influencing various cellular processes including its coupling with G protein-coupled receptor signaling and cell migration through interaction with CCDC88A/GIV. Isoform 2 of EGFR may act as an antagonist to EGF actions. In microbial infection, EGFR also serves as a receptor facilitating hepatitis C virus (HCV) entry into hepatocytes by promoting CD81-CLDN1 receptor complexes and enhancing membrane fusion with HCV envelope glycoproteins.
