== Disease ==
[https://www.uniprot.org/uniprot/EGFR_HUMAN EGFR_HUMAN] Defects in EGFR are associated with lung cancer (LNCR) [MIM:[https://omim.org/entry/211980 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.
== Function ==
[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>
