Supplementary information

EGFR or Epidermal Growth Factor Receptor is a transmembrane glycoprotein that acts as a receptor for members of the epidermal growth factor family. Known alternatively as ErbB1 or HER1 this receptor has an approximate molecular weight of 170 kDa. EGFR is expressed in various cell types notably on epithelial cells and can influence multiple cellular processes through its kinase activity. It participates in the regulation of cell growth multiplication and survival by activating its kinase domain upon ligand binding.
Biological function summary

The EGFR protein plays an important role in cellular communication and signaling processes. EGFR pairs with other receptor family members to form active dimers or even higher-order complexes which in turn initiate intracellular signaling cascades. Through these complexes EGFR influences many processes including cell differentiation and repair. This function of EGFR makes it an integral part of mammalian biology affecting how cells respond to their environment by mediating changes in gene expression.

Pathways

EGFR is a central player in the MAPK and PI3K/Akt signaling pathways. Alongside other protein partners like KRAS and PI3 kinase it contributes to transmitting signals from the cell surface to the nucleus affecting gene transcription and cell behavior. These pathways are important for normal cell growth and division and aberrations in these pathways can lead to excessive or insufficient cell proliferation.

EGFR is pertinent to cancer biology including non-small cell lung cancer and glioblastoma where mutations or overexpression of the receptor frequently occur. It connects to proteins such as PTEN and BRAF which influence tumor progression and response to targeted therapies. EGFR's involvement in these disorders highlights its significance as a therapeutic target since it can be manipulated to alter disease progression.

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.
