[https://www.uniprot.org/uniprot/EGFR_HUMAN EGFR_HUMAN] 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.<ref>PMID:7657591</ref> <ref>PMID:11602604</ref> <ref>PMID:12873986</ref> <ref>PMID:10805725</ref> <ref>PMID:11116146</ref> <ref>PMID:11483589</ref> <ref>PMID:17115032</ref> <ref>PMID:21258366</ref> <ref>PMID:12297050</ref> <ref>PMID:12620237</ref> <ref>PMID:15374980</ref> <ref>PMID:19560417</ref> <ref>PMID:20837704</ref> Isoform 2 may act as an antagonist of EGF action.<ref>PMID:7657591</ref> <ref>PMID:11602604</ref> <ref>PMID:12873986</ref> <ref>PMID:10805725</ref> <ref>PMID:11116146</ref> <ref>PMID:11483589</ref> <ref>PMID:17115032</ref> <ref>PMID:21258366</ref> <ref>PMID:12297050</ref> <ref>PMID:12620237</ref> <ref>PMID:15374980</ref> <ref>PMID:19560417</ref> <ref>PMID:20837704</ref>

A novel series of small molecule inhibitors has been developed to target the double mutant form of the epidermal growth factor receptor (EGFR) tyrosine kinase, which is resistant to treatment with gefitinib and erlotinib. Our reported compounds also show selectivity over wild-type EGFR. Guided by molecular modelling this series was evolved to target a cysteine residue in the ATP binding site via covalent bond formation and demonstrates high levels of activity in cellular models of the double mutant form of EGFR. In addition, these compounds show significant activity against the L858R activating mutant, which gefitinib and erlotinib target and inhibition of which gives rise to their observed clinical efficacy. A glutathione (GSH) based assay has been used to measure thiol reactivity towards the electrophilic functionality of the inhibitor series enabling both the identification of a suitable reactivity window for potency and the development of reactivity quantitative structure property relationship (QSPR) to support design.
