  • 機能

    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.

  • 組織特異性

    Ubiquitously expressed. Isoform 2 is also expressed in ovarian cancers.

  • 関連疾患

    Inflammatory skin and bowel disease, neonatal, 2

  • 配列類似性

    Belongs to the protein kinase superfamily. Tyr protein kinase family. EGF receptor subfamily.
    Contains 1 protein kinase domain.

  • 翻訳後修飾

    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.

In response to EGF, translocated from the cell membrane to the nucleus via Golgi and ER. Endocytosed upon activation by ligand.

    Question

    I am looking for an EGFR antibody that recognizes the N-term (extracellular domain) of EGFR but does not block EGF binding to EGFR. I need the antibody for flow cytometry experiments.

    Read More
    Answer

    This antibody recognizes the extracellular domain of EGFR and is validated for flow cytometry. There is data demonstrating the effects of the antibody on binding of EGF to EGFR in the reference at the following link.

    http://onlinelibrary.wiley.com/doi/10.1002/ijc.11055/pdf

    The data in figure 3 shows that ICR10 blocks partially, compared to the medium control. receptor.

    Question

    Do you know the isoelectric point of the Rat monoclonal ICR10 antibody, abcam part number ab231?

    Read More
    Answer

    Most monoclonal antibodies will have an isoelectric point around 6.1, but this is not something that we test except for some of our RabMab antibodies.

    Question

    Customer would like to know if these EGFR antibodies are specific for the truncated receptor.

    Read More
    Answer

    Thank you for your patience. I have received the following information thus far: Ab231: In Western blotting ab231 detects a 170kDa band which corresponds to EGFR. The epitope recognized by this antibody is located on the extracellular domain of the EGFR. I belive that the truncated form of EGFR lacks the cytoplasmic and transmembrane domain. If it is indeed this simple, then I would expect the antibody to recognise the truncated form. However, to our knowledge, this antibody has not been tested for reactivity with this form of EGFR and therefore we would be unable to offer any guarantees. Ab2430: Ab2430 is made using a peptide corresponding to AA 1005-1016 of the human EGFR precursor. There are several truncated forms of EGFR and one of the more prevelant is EGFRvIII where amino acids 6-273 are replaced by a glycine residue. This antibody will recognize this variant, but it will also recognize the wild type. The researcher will need to compare the variants sequence to that of the wild type to make sure that this antibody's epitope has not been deleted. Once I receive more information regarding ab5636 and ab30, I will contact you again.
