    • 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
      modifications
      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).

The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab30, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

    Question

    Hi,   Can you please let me know the concentration of this antibody? Anti-EGFR antibody [EP38Y] (ab52894). I am looking for an EGFR monoclonal antibody which concentration is at least or higher than 1mg/ml.  Do you have anyone match these criteria?   Appreciate your help!!

    Read More
    Answer

    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.

    Question

    Thank you very much for giving me many advice.
    Last year our lab bought one antibody against EGFR (ab24293)from your company. I found it didn't work on my cell line H1703 (somebody reported EGFR was expressed on the surface of H1703 cell line with Western blotting method.)
    Yesterday you guarantee the antibody (ab30) should work follow your company method. I am planning to buy it. But my boss want to know if the antibody doesn't work again, whether your company can completely refund to us? Thank you again.

    Answer

    Thank you for your reply.

    The antibody ab30 will be covered under our Abpromise guarantee for use in ICC on human cells. If for any reason you are unsatisfied with the results, we will be happy to refund or replace it for you as long as you contact us within six months of purchase. I hope this helps, pleaselet me know if you have any additional questionsor concerns.

Our customer repeated the ELISA assay three times but the signal remains to be very weak.(Raw data is available) Our customer has generated EGFR antibody which works well in ELISA and WB and needed a commercial antibody (ab30)to serve as a positive control. But it seems like the titer of ab30 is extremely low. Our customer would like to try ab231 if a replacement can be processed again for this case.

    Answer

    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,
