  • Target

    • Function
      Receptor tyrosine kinase binding ligands of the EGF family and activating several signaling cascades to convert extracellular cues into appropriate cellular responses. Known ligands include EGF, TGFA/TGF-alpha, amphiregulin, epigen/EPGN, BTC/betacellulin, epiregulin/EREG and HBEGF/heparin-binding EGF. Ligand binding triggers receptor homo- and/or heterodimerization and autophosphorylation on key cytoplasmic residues. The phosphorylated receptor recruits adapter proteins like GRB2 which in turn activates complex downstream signaling cascades. Activates at least 4 major downstream signaling cascades including the RAS-RAF-MEK-ERK, PI3 kinase-AKT, PLCgamma-PKC and STATs modules. May also activate the NF-kappa-B signaling cascade. Also directly phosphorylates other proteins like RGS16, activating its GTPase activity and probably coupling the EGF receptor signaling to the G protein-coupled receptor signaling. Also phosphorylates MUC1 and increases its interaction with SRC and CTNNB1/beta-catenin.
      Isoform 2 may act as an antagonist of EGF action.
    • Tissue specificity
      Ubiquitously expressed. Isoform 2 is also expressed in ovarian cancers.
    • Involvement in disease
      Lung cancer
      Inflammatory skin and bowel disease, neonatal, 2
    • Sequence similarities
      Belongs to the protein kinase superfamily. Tyr protein kinase family. EGF receptor subfamily.
      Contains 1 protein kinase domain.
    • Post-translational
      Phosphorylation at Ser-695 is partial and occurs only if Thr-693 is phosphorylated. Phosphorylation at Thr-678 and Thr-693 by PRKD1 inhibits EGF-induced MAPK8/JNK1 activation. Dephosphorylation by PTPRJ prevents endocytosis and stabilizes the receptor at the plasma membrane. Autophosphorylation at Tyr-1197 is stimulated by methylation at Arg-1199 and enhances interaction with PTPN6. Autophosphorylation at Tyr-1092 and/or Tyr-1110 recruits STAT3. Dephosphorylated by PTPN1 and PTPN2.
      Monoubiquitinated and polyubiquitinated upon EGF stimulation; which does not affect tyrosine kinase activity or signaling capacity but may play a role in lysosomal targeting. Polyubiquitin linkage is mainly through 'Lys-63', but linkage through 'Lys-48', 'Lys-11' and 'Lys-29' also occurs. Deubiquitination by OTUD7B prevents degradation. Ubiquitinated by RNF115 and RNF126.
      Methylated. Methylation at Arg-1199 by PRMT5 stimulates phosphorylation at Tyr-1197.
    • Cellular localization
      Secreted and Cell membrane. Endoplasmic reticulum membrane. Golgi apparatus membrane. Nucleus membrane. Endosome. Endosome membrane. Nucleus. In response to EGF, translocated from the cell membrane to the nucleus via Golgi and ER. Endocytosed upon activation by ligand. Colocalized with GPER1 in the nucleus of estrogen agonist-induced cancer-associated fibroblasts (CAF).

    • Overlay histograms showing left positive A431 cells and right negative Jurkat cells stained with ab30 (red line). The cells were incubated in 1x PBS / 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (ab30, 1x106 cells in 100ul at 1ug/ml) for 30 min on ice. The secondary antibody used was Alexa Fluor® 488 goat anti-mouse IgG (H&L) preabsorbed (ab150117) at 1/2000 dilution for 30 min on ice.

      Isotype control antibody (black line) was mouse IgG2bκ (ab170192) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

      Acquisition of >5,000 events were collected using a 50 mW Blue laser (488nm) and 530/30 bandpass filter.

    • ab30 staining EGFR (colored green) in A431 cells. The cells were fixed with 4% formaldehyde (10min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab30 at 5μg/ml overnight at 4ºC. Cells were then incubated with ab150117, Goat Anti-Mouse IgG H&L (Alexa Fluor® 488) at 1/1000 dilution (shown in green). Nuclear DNA was labelled with DAPI (shown in blue).

      Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

    • IHC image of EGFR staining in a section of frozen normal human placenta, fixed in 10% paraformaldehyde (10 min). Staining was performed on a Leica BONDTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab30, 10ug/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody.

      For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

    Thank you for contacting us.

    Rabbit monoclonals typically have 10-100x the affinity of mouse monoclonals, as such it is often the case that the concentration of a rabbit monoclonal will be lower than a mouse monoclonal. Ab52894 does not have a concentration of near 1 mg/ml.

    We do offer two EGFR monoclonal antibodies which do have concentrations over 1mg/ml. These are ab30 and ab62. I have included the links to those products below.

    I'm sorry to hear you are still having problems with the replacement of ab30, this must be very fustrating. I understand that my colleague Danielle has raised the possibility that "this antibody does not recognise recombinant EGFR. The epitope has been mapped to between aa 6-273 of human EGFR and this stretch of AAs is included in the recombinant protein used in this research. The epitope maps to the external EGF-binding domain of the EGFR transmembrane glycoprotein and perhaps this region of the recominant protein is not in the correct configuration for the antibody to bind" (e-mail from 28th Sept 2004). I would like to suggest trying an overnight incubation with the primary antibody (at 4C) to enable better binding and if this is still unsuccessful we can arrange for a credit note or replacement with ab231 (please note this antibody had not been tested for ELISA) . Please let me know if this helps and do not hesitate to contact us for further advice,
