QuicKey Pro Mouse EGFR (Epidermal Growth Factor Receptor) ELISA Kit

Epidermal Growth Factor Receptor (EGFR) is a receptor tyrosine kinase that links extracellular mitogenic ligand binding to complex downstream signaling cascades. Initial ligand binding results in receptor oligomerization and autophosphorylation of multiple tyrosine residues within cytosolic domains of the the protein. These phosphorylation events stabilize the EGFR kinase activation loop and lead to the recruitment of adaptor proteins and other downstream effectors. EGFR stimulation leads to activation of RAS-RAF-MEK-ERK, PI3 kinase-AKT, PLCgamma-PKC and STAT signaling cascades, and constitutive activation of the receptor promotes tumorigenesis in multiple cancers.Gene AliasEgfrGene ID13649Uniport IDQ01279Protein AliasEgfrResearch AreaCell Biology Protein function: Receptor tyrosine kinase binding ligands of the EGF family and activating several signaling cascades to convert extracellular cues into appropriate cellular responses (PubMed:8404850). Known ligands include EGF, TGFA/TGF-alpha, AREG, 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. Positively regulates cell migration via interaction with CCDC88A/GIV which retains EGFR at the cell membrane following ligand stimulation, promoting EGFR signaling which triggers cell migration. Plays a role in enhancing learning and memory performance (PubMed:20639532). Plays a role in mammalian pain signaling (long- lasting hypersensitivity) (PubMed:35131940). [The UniProt Consortium]
