|Protein Name||Epidermal growth factor receptor|
|Molecular Weight||134277 MW|
|Protein 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.|
|Tissue Specificity||Ubiquitously expressed. Isoform 2 is also expressed in ovarian cancers. .|
|Sequence Similarities||Belongs to the protein kinase superfamily. Tyr protein kinase family. EGF receptor subfamily.|
|Subcellular Localization||Cell membrane; Single-pass type I membrane protein. Endoplasmic reticulum membrane; Single-pass type I membrane protein. Golgi apparatus membrane; Single-pass type I membrane protein. Nucleus membrane; Single-pass type I membrane protein. 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).|

- Review by Elena Deryugina
"I would highly recommend this Boster antibody..."
--Elena Deryugina, CELL AND MOLECULAR BIOLOGY, THE SCRIPPS RESEARCH INSTITUTE, ASSISTANT PROFESSOR
Applications Western Blot Sample Recombinant N-Terminal domain of human EGFR (aa 1-621) tested at 100 ng/lane Detection SuperSignal West Pico Chemiluminescent Substrate
"Rabbit antibody PB9016 from Boster was probed for western blot detection of the recombinant N-terminal domain of human EGFR (100 ng/lane). The antibody nicely detected the protein band with the expected mol.wt. of recombinant protein. The antibody appears to be specific since non-specific bands were not detected in parallel lanes with cell lysates lacking EGFR. I would highly recommend this Boster antibody for detection of EGFR with the intact N-terminal domain."
1. Post-translational modification:phosphorylation, methylation, glycosylation etc. These modifications prevent SDS molecules from binding to the target protein and thus make the band size appear larger than expected
2. Post-translational cleavage: this can cause smaller bands and or multiple bands
3. Alternative splicing: the same gene can have alternative splicing patterns generating different size proteins, all with reactivities to the antibody.
4. Amino Acid R chain charge: SDS binds to positive charges. The different size and charge of the Amino Acid side chains can affect the amount of SDS binding and thus affect the observed band size.
5. Multimers: Multimers are usually broken up in reducing conditions. However if the interactions between the multimers are strong, the band may appear higher.,
