      Alternate Names
      • Receptor tyrosine-protein kinase ErbB-1
      Background InformationEGFR (Epidermal growth factor receptor, ErbB-1) is a receptor tyrosine kinase (RTK) that is one of four members of the EGFR/ErbB family of receptor tyrosine kinases. EGFR plays a key role in the regulation of essential normal cellular processes and in the pathophysiology of hyperproliferative diseases such as cancer. EGFR is found in most solid tumors and it is known to be essential for mediation of both proliferative and survival signals to cells. Activation of the EGFR signaling pathway has been linked with increased cell proliferation, angiogenesis, metastasis and decreased apoptosis. Upon activation by its growth factor ligands, EGFR undergoes a transition from an inactive monomeric form to an active dimer. In addition to forming homodimers after ligand binding, EGFR may pair with another member of the ErbB receptor family, such as ErbB2/Her2/neu, to create an activated heterodimer. EGFR dimerization stimulates its intrinsic intracellular protein-tyrosine kinase activity that leads to trans- and auto-phosphorylation of tyrosine residues within the cytoplasmic domain of the receptor tyrosine kinase of five tyrosine (Y) residues on sites Y992, Y1045, Y1068, Y1148 and Y1173 located on the C-terminal domain of EGFR. This autophosphorylation elicits downstream activation of several signal transduction cascades, principally the MAPK, Akt and JNK pathways through Ras, PI3 Kinase, and PLC pathways that ultimately leads to the activation of the various pathways downstream including the classical MAPK signaling pathway, that leads to DNA synthesis, cell proliferation, adhesion, and migration.

      Entrez Gene Number
      Entrez Gene SummaryThe 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.

      UniProt Number
      UniProt SummaryFUNCTION: Receptor for EGF, but also for other members of the EGF family, as TGF-alpha, amphiregulin, betacellulin, heparin-binding EGF-like growth factor, GP30 and vaccinia virus growth factor. Is involved in the control of cell growth and differentiation. Phosphorylates MUC1 in breast cancer cells and increases the interaction of MUC1 with C-SRC and CTNNB1/beta-catenin.
      FUNCTION: Isoform 2/truncated isoform may act as an antagonist.
      CATALYTIC ACTIVITY: ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.
      SUBUNIT: Binds RIPK1. CBL interacts with the autophosphorylated C-terminal tail of the EGF receptor. Part of a complex with ERBB2 and either PIK3C2A or PIK3C2B. The autophosphorylated form interacts with PIK3C2B, maybe indirectly. Interacts with PELP1. Binds MUC1.
      SUBCELLULAR LOCATION: Cell membrane; Single-pass type I membrane protein.
      SUBCELLULAR LOCATION: Isoform 2: Secreted.
      ALTERNATIVE PRODUCTS: 4 named isoforms [FASTA] produced by alternative splicing.
