Detection of EGFR by Western Blot

The EGFR expression upon cell stimulation with EGF.(A) Representative Western blot images showing expression of phosphorylated- and total-EGFR (Phospho-EGFR and Total-EGFR), upon EGF stimulation at different time points. GAPDH served as an internal control for protein loading. The average expression values of the indicated protein were determined via densitometry (Fiji software) from three independent experiments and presented as a fold change over the negative controls. Increased expression is marked in green and decreased in red. Full Western blot images including the corresponding controls for each time point and weight marker are shown in Supplementary Figure S2. (B) Localization of EGFR upon cell stimulation with EGF assessed via confocal microscopy. Receptor internalization was observed 5 min after A549 stimulation with EGF, followed by receptor recycling back to the membrane staring at 15 min. Magenta: EGFR;Cyan: nuclei. Scale bar: 10 μm.

Background: EGFR

The epidermal growth factor receptor (EGFR) subfamily of receptor tyrosine kinases comprises four members: EGFR (also known as HER1, ErbB1 or ErbB), ErbB2 (Neu, HER2), ErbB3 (HER3), and ErbB4 (HER4). All family members are type I transmembrane glycoproteins that have an extracellular domain which contains two cysteine-rich domains separated by a spacer region that is involved in ligand binding, and a cytoplasmic domain which has a membrane-proximal tyrosine kinase domain and a C-terminal tail with multiple tyrosine autophosphorylation sites. The human EGFR gene encodes a 1210 amino acid (aa) residue precursor with a 24 aa putative signal peptide, a 621 aa extracellular domain, a 23 aa transmembrane domain, and a 542 aa cytoplasmic domain. EGFR has been shown to bind a subset of the EGF family ligands, including EGF, amphiregulin, TGF-alpha, betacellulin, epiregulin, heparin-binding EGF and neuregulin-2 alpha  in the absence of a co-receptor. Ligand binding induces EGFR homodimerization as well as heterodimerization with ErbB2, resulting in kinase activation, tyrosine phosphorylation and cell signaling. EGFR can also be recruited to form heterodimers with the ligand-activated ErbB3 or ErbB4. EGFR signaling has been shown to regulate multiple biological functions including cell proliferation, differentiation, motility and apoptosis. In addition, EGFR signaling has also been shown to play a role in carcinogenesis (1 - 3).
