纯化说明
The antibody has been negatively preadsorbed using (i) a non phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated epidermal growth factor receptor (EGFR), and (ii) a generic tyrosine phosphorylated peptide to remove antibody that is reactive with phosphotyrosine, irrespective of the sequence. The final product is generated by affinity chromatography using an EGFR-derived peptide that is phosphorylated at tyrosine 1068. -

功能
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. -

翻译后修饰
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. -

Immunocytochemistry/ Immunofluorescence - Anti-EGFR (phospho Y1068) antibody (ab5644)
Immunofluorescence analysis of A431 (Human epidermoid carcinoma cell line) cells labeling EGFR with ab5644 at 1/100 dilution, followed by Goat anti-rabbit IgG (H+L) Superclonal, Alexa Fluor® 488 conjugate was used as the secondary antibody at 1/2000 dilution (Panel a). Nuclei (Panel b) were stained with SlowFade® Gold Antifade Mountant with DAPI. F-actin (Panel c) was stained with Rhodamine Phalloidin. Panel (d) represents the merged image showing membrane localization. Panel (e) represents cells treated with antagonist, Afatinib (1µM for 6hrs) followed by EGF (200 ng/ml for 10 minutes), showing no Phospho-EGFR staining. Panel (f) shows untreated cells with no signal. Panel (g) represents control cells with no primary antibody to assess background.
The cells (in 70% confluent log phase treated with 200ng/ml of EGF for 10 minutes) were fixed with 4% paraformaldehyde for 10 minutes; permeabilized with 0.1% Triton X-100 for 10 minutes and blocked with 1% BSA for hour at room temperature. The images were captured at 60X magnification.

Secondary
All lanes : Goat anti-Rabbit IgG Superclonal Secondary Antibody, HRP at 1/4000 dilutionWestern blot analysis using ab5644 shows increased expression of proteins phosphorylated at the tyrosine residues in A-431 and A549 cell lines upon EGF treatment and pre-treatment with EGFR-antagonists, Gefitinib and Afatinib. This results in inhibition of Phospho-EGFR in A-431 and A549 cell lines
