===Crystal structure of the complex between the EGFR kinase domain and a Mig6 peptide===
==Disease==
[[http://www.uniprot.org/uniprot/EGFR_HUMAN EGFR_HUMAN]] Defects in EGFR are associated with lung cancer (LNCR) [MIM:[http://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==
[[http://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> [[http://www.uniprot.org/uniprot/ERRFI_HUMAN ERRFI_HUMAN]] Negative regulator of EGFR signaling in skin morphogenesis. Acts as a negative regulator for several EGFR family members, including ERBB2, ERBB3 and ERBB4. Inhibits EGFR catalytic activity by interfering with its dimerization. Inhibits autophosphorylation of EGFR, ERBB2 and ERBB4. Important for normal keratinocyte proliferation and differentiation. Plays a role in modulating the response to steroid hormones in the uterus. Required for normal response to progesterone in the uterus and for fertility. Mediates epithelial estrogen responses in the uterus by regulating ESR1 levels and activation. Important for regulation of endometrium cell proliferation. Important for normal prenatal and perinatal lung development (By similarity).
