• Description
  Rabbit monoclonal [EP774Y] to EGFR (phospho Y1092)
• SpecificityThe 1092 numbering includes the 24 aa signal peptide that is cleaved during EGFR maturation (the signal peptide is 24aa long based on Swiss Prot #P00533). Essentially, the Tyrosine 1068 of mature EGFR is equivalent to Tyrosine 1092 of uncleaved EGFR.

Applications

Target

• FunctionReceptor 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 specificityUbiquitously expressed. Isoform 2 is also expressed in ovarian cancers.
• Involvement in diseaseDefects in EGFR are associated with lung cancer (LNCR) [MIM:211980]. LNCR is a common malignancy affecting tissues of the lung. The most common form of lung cancer is non-small cell lung cancer (NSCLC) that can be divided into 3 major histologic subtypes: squamous cell carcinoma, adenocarcinoma, and large cell lung cancer. NSCLC is often diagnosed at an advanced stage and has a poor prognosis.
• Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. EGF receptor subfamily.
  Contains 1 protein kinase domain.
• Post-translational
  modificationsPhosphorylation 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.
  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 occur. Deubiquitinated by OTUD7B, preventing degradation.
  Methylated. Methylation at Arg-1199 by PRMT5 positively stimulates phosphorylation at Tyr-1197.
• Cellular localizationSecreted and Cell membrane. Endoplasmic reticulum membrane. Golgi apparatus membrane. Nucleus membrane. Endosome. Endosome membrane. In response to EGF, translocated from the cell membrane to the nucleus via Golgi and ER. Endocytosed upon activation by ligand.

Tissue underwent fixation in paraformaldehyde, heat mediated antigen retrieval using 10mM Sodium Citrate buffer (pH 6.0) for 10 min at 95°C in a pressurized chamber and blocking in 5% serum for 1 hour at 25°C. Endogenous peroxidases were quenched with 3% H₂o₂ for 10 minutes. The primary antibody was diluted 1/250 in NGS buffer and incubated with sample for 8 hours at 4°C. A Biotin-conjugated goat polyclonal to rabbit IgG, diluted 1/500 was used as secondary. 1XTBS/0.1% Tween-20 (TBST) gave minimum background over 1XPBS as wash buffer.
