Function
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.

Notes
Abcam's EGFR (ERBB) Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human EGFR in serum, plasma, and cell culture supernatants.
This assay employs an antibody specific for Human EGFR coated on a 96-well plate. Standards and samples are pipetted into the wells and EGFR present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated antiHuman EGFR antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of EGFR bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
Get higher sensitivity in only 90 minutes with Human soluble EGFR ELISA Kit (ab193764) from our SimpleStep ELISA® range.
Optimisation may be required with urine samples.

- Activity summary
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.
- Associated diseases and disorders
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.
