[14][15], Mutations that lead to EGFR overexpression (known as upregulation or amplification) have been associated with a number of cancers, including adenocarcinoma of the lung (40% of cases), anal cancers,[16] glioblastoma (50%) and epithelian tumors of the head and neck (80-100%). [10] Such proteins modulate phenotypes such as cell migration, adhesion, and proliferation. Many therapeutic approaches are aimed at the EGFR. EGFR-activating mutations are observed in approximately 15% to 20% of patients with non–small cell lung cancer. An interdisciplinary consensus on managing skin reactions associated with human epidermal growth factor receptor inhibitors. doi:10.1146/annurev.bi.56.070187.004313. Epidermal growth factor receptor (EGFR) inhibitors prevent cell growth and have shown benefit in the treatment of metastatic colorectal cancer, whether used as single agents or in combination with chemotherapy. CimaVax-EGF, an active vaccine targeting EGF as the major ligand of EGF, uses a different approach, raising antibodies against EGF itself, thereby denying EGFR-dependent cancers of a proliferative stimulus;[29] it is in use as a cancer therapy against non-small-cell lung carcinoma (the most common form of lung cancer) in Cuba, and is undergoing further trials for possible licensing in Japan, Europe, and the United States. Epidermal Growth Factor Receptor, EGFR, is a transmembrane tyrosine kinase that binds to the EGF-family of ligands. It activates several downstream signaling cascades, including MAPK, and leads to DNA synthesis and cell proliferation. Ostensibly by halting the signaling cascade in cells that rely on this pathway for growth, tumor proliferation and migration is diminished. The pathogenicity of the EGFR mutation was supported by in vitro experiments and functional analysis of a skin biopsy. The EGFR is essential for ductal development of the mammary glands,[11][12][13] and agonists of the EGFR such as amphiregulin, TGF-α, and heregulin induce both ductal and lobuloalveolar development even in the absence of estrogen and progesterone. Aberrant EGFR signaling has been implicated in psoriasis, eczema and atherosclerosis. As a result, autophosphorylation of several tyrosine (Y) residues in the C-terminal domain of EGFR occurs. EGFR (aka. T790M, also known as Thr790Met, is a gatekeeper mutation of the epidermal growth factor receptor (EGFR). EGFR-positive patients have shown a 60% response rate, which exceeds the response rate for conventional chemotherapy.[32]. ; Wu, YL. A hydrochloride acid salt form of Erlotinib which is a HER1/EGFR tyrosine kinase inhibitor for HER1/EGFR tyrosine kinase with an IC 50 of 2 nM. Tyrosinkinase-Inhibitoren sind Hemmstoffe, die verschiedene Enzyme aus der Gruppe der Tyrosinkinasen hemmen. The small molecule EGFR inhibitors, such as erlotinib, gefitinib and lapatinib, compete with ATP to bind the catalytic domain of the kinase which in turn inhibits EGFR autophosphorylation and downstream signaling. However the former is of the IgG1 type, the latter of the IgG2 type; consequences on antibody-dependent cellular cytotoxicity can be quite different. EGFR (aka. They work by inhibiting growth factor activity and controlling cell division. ; Cheng, Y.; Zhou, X.; Lee, KH. Tyrosine kinase inhibitors (TKIs) generally target proteins in the epidermal growth factor receptor (EGFR) family and have been developed as a cancer therapy that … From HemOnc.org - A Hematology Oncology Wiki. [8] – although there is some evidence that preformed inactive dimers may also exist before ligand binding. [33] In 10% to 15% of patients the effects can be serious and require treatment. "Afatinib versus cisplatin-based chemotherapy for EGFR mutation-positive lung adenocarcinoma (LUX-Lung 3 and LUX-Lung 6): analysis of overall survival data from two randomised, phase 3 trials.". Without kinase activity, EGFR is unable to activate itself, which is a prerequisite for binding of downstream adaptor proteins. [38], Imaging agents have been developed which identify EGFR-dependent cancers using labeled EGF. The first-line agent for treating EGFR mutant lung cancer is an FDA-approved medication called Tagrisso (osimertinib).11 Tagrisso is a tyrosine kinase inhibitor that blocks the activity of the EGFR protein. "Osimertinib for the treatment of patients with". Two primary sources of resistance are the T790M Mutation and MET oncogene. The epidermal growth factor receptor (EGFR) is a receptor tyrosine kinase of the ErbB family. effective when del19 is present. Tyrosine kinase inhibitors have provided an illustrative example of the successes in targeting oncogene addiction in cancer and the role of tumor-specific adaptations conferring therapeutic resistance. "Improvement in Overall Survival in a Randomized Study That Compared Dacomitinib With Gefitinib in Patients With Advanced Non-Small-Cell Lung Cancer and EGFR-Activating Mutations.". [28] Other monoclonals in clinical development are zalutumumab, nimotuzumab, and matuzumab. The EGFR gene provides instructions for making a receptor protein called the epidermal growth factor receptor, which spans the cell membrane so that one end of the protein remains inside the cell and the other end projects from the outer surface of the cell. [citation needed]. Erlotinib (an EGFR tyrosine kinase inhibitor) was the first … Upon activation by its growth factor ligands, EGFR undergoes a transition from an inactive monomeric form to an active homodimer. In many cancer types, mutations affecting EGFR expression or activity could result in cancer.[6]. These medications are referred to as tyrosine kinase inhibitors. However, these inhibitors are known to be effective in only a small subset of patients. Gefitinib selectively inhibits EGF-stimulated tumor cell growth (IC 50 of 54 nM) and that blocks EGF-stimulated EGFR autophosphorylation in tumor cells. More recently AstraZeneca has developed Osimertinib, a third generation tyrosine kinase inhibitor.[27]. The identification of EGFR as an oncogene has led to the development of anticancer therapeutics directed against EGFR (called "EGFR inhibitors"), including gefitinib,[25] erlotinib, afatinib, brigatinib and icotinib[26] for lung cancer, and cetuximab for colon cancer. Tyrosine kinase inhibitors directed against the epidermal growth factor receptor (EGFR) are the first molecular-targeted agents to be approved in the US and other countries for the treatment of advanced non-small-cell lung cancer after failure of chemotherapy. Recent studies show that inhibitors of the EGFR kinase will only be useful if the receptor plays a major role in the survival of the cancer or if the drug can be combined with other signal tranduction agents to cause certain cancer cells to kill themselves. Subcategories. Some patient characteristics, such as never-smoking, female gender, East Asian origin, adenocarcinoma histology, and bronchioloalveolar subtype, are associated with a greater benefit from treatment with EGFR inhibitors. (Feb 2015). 1ivo: Crystal Structure of the Complex of Human Epidermal Growth Factor and Receptor Extracellular Domains. Epidermal Growth Factor Receptor Inhibitors. EGFR inhibitors are used to treat colon cancer, skin cancer, lung cancer, and pancreatic cancer. EGFR-activating mutations are observed in approximately 15% to 20% of patients with non–small cell lung cancer. et al. Interruption of EGFR signalling, either by blocking EGFR binding sites on the extracellular domain of the receptor or by inhibiting intracellular tyrosine kinase activity, can prevent the growth of EGFR-expressing tumours and improve the patient's condition. Gefitinib also induces autophagy. Y… "Receptors for epidermal growth factor and other polypeptide mitogens". • Carpenter G (1987). ErbB1 or HER1) is a membranous receptor expressed in epithelial cells. [34][35], Some tests are aiming at predicting benefit from EGFR treatment, as Veristrat.

They block the activity of the EGFR protein. Recently, studies have identi… EGFR Inhibitors. 4th Gen EGFR Inhibitor T790M mutation is the most common mechanism of resistance to first- and second-generation tyrosine kinase inhibitors (TKI) for epidermal growth factor receptor (EGFR). Afatinib (Gilotrif) - esp. Clin J Oncol Nurs. Epidermal growth factor receptor inhibitors, abbreviated EGFR inhibitors, is a class of drugs that blocks the EGF receptor. With the binding site blocked, signal molecules can no longer attach there and activate the tyrosine kinase. Alsharedi, M.; Bukamur, H.; Elhamdani, A. A protein kinase inhibitor is a type of enzyme inhibitor that blocks the action of one or more protein kinases.Protein kinases are enzymes that add a phosphate (PO 4) group to a protein, and can modulate its function.. A. Anti-EGFR antibodies; Pages in category "EGFR inhibitors" [5], The epidermal growth factor receptor is a member of the ErbB family of receptors, a subfamily of four closely related receptor tyrosine kinases: EGFR (ErbB-1), HER2/neu (ErbB-2), Her 3 (ErbB-3) and Her 4 (ErbB-4). Im medizinischen Sinne werden darunter chemische Substanzen verstanden, die speziell für die Hemmung von bestimmten Tyrosinkinasen … Epidermal growth factor receptor (EGFR) is a transmembrane protein that is activated by binding of its specific ligands, including epidermal growth factor and transforming growth factor α (TGFα)[7] ErbB2 has no known direct activating ligand, and may be in an activated state constitutively or become active upon heterodimerization with other family members such as EGFR. ... Ye et al. [19] Mutations, amplifications or misregulations of EGFR or family members are implicated in about 30% of all epithelial cancers. Epidermal Growth Factor Receptor, EGFR) ist ein Protein in Zellmembranen von Wirbeltieren; es ist der Rezeptor für den Epidermal-Growth-Factor (EGF) und ist ein Mitglied der ErbB-Familie, eine Unterfamilie von vier eng verwandten Rezeptor-Tyrosinkinasen: EGFR1/HER1 (ErbB-1), HER2/c-neu (ErbB-2), HER3 (ErbB-3) und HER4 (ErbB-4). 1IVO, 1M14, 1M17, 1MOX, 1NQL, 1XKK, 1YY9, 1Z9I, 2EB2, 2EB3, 2GS2, 2GS6, 2GS7, 2ITN, 2ITO, 2ITP, 2ITQ, 2ITT, 2ITU, 2ITV, 2ITW, 2ITY, 2ITZ, 2J5E, 2J5F, 2J6M, 2JIT, 2JIU, 2JIV, 2KS1, 2M0B, 2M20, 2RF9, 2RFD, 2RFE, 2RGP, 3B2U, 3B2V, 3BEL, 3BUO, 3C09, 3G5V, 3G5Y, 3GOP, 3GT8, 3IKA, 3LZB, 3NJP, 3OB2, 3OP0, 3P0Y, 3PFV, 3POZ, 3QWQ, 3UG1, 3UG2, 3VJN, 3VJO, 3VRP, 3VRR, 3W2O, 3W2P, 3W2Q, 3W2R, 3W2S, 3W32, 3W33, 4G5J, 4G5P, 4HJO, 4I1Z, 4I20, 4I21, 4I22, 4I23, 4I24, 4JQ7, 4JQ8, 4JR3, 4JRV, 4KRL, 4KRM, 4KRO, 4KRP, 4LI5, 4LL0, 4LQM, 4LRM, 4R3P, 4R3R, 4R5S, 4RIW, 4RIX, 4RIY, 4RJ4, 4RJ5, 4RJ6, 4RJ7, 4RJ8, 4TKS, 4WKQ, 4WRG, 4ZJV, 5CNN, 5CNO, 5CAN, 2N5S, 5CAL, 5C8M, 4UV7, 5CAV, 5CZI, 5EDQ, 5CAS, 5CAO, 5CAP, 5EM5, 5HG5, 5EDR, 5EM8, 5EDP, 5HG7, 5CAU, 5C8K, 5C8N, 5CZH, 5CAQ, 5EM6, 4UIP, 5HG9, 5EM7, 5HG8, 4ZSE, 5HIB, 5HIC, 5D41, 4WD5, The epidermal growth factor receptor (EGFR; ErbB-1; HER1 in humans) is a transmembrane protein that is a receptor for members of the epidermal growth factor family (EGF family) of extracellular protein ligands.

His clinical features included a papulopustular rash, dry skin, chronic diarrhoea, abnormalities of hair growth, breathing difficulties and electrolyte imbalances.[22]. Clear benefit has been shown in trials of EGFR monoclonal antibodies (EGFR MAb) but not EGFR tyrosine kinase inhibitors (EGFR TKI). [39] The feasibility of in vivo imaging of EGFR expression has been demonstrated in several studies.[40][41]. 45% of the mutations are p.DEL19, approx 40-45% are p.L858R, approx 2% are p.T790M. The mutation substitutes a threonine (T) with a methionine (M) at position 790 of exon 20, affecting the ATP binding pocket of the EGFR kinase domain. However, initial clinical studies have shown modest responses to EGFR inhibitors when used alone, and it has not yet been possible to clearly identify which tumours will respond to this therapy. Epidermal growth factor and its receptor was discovered by Stanley Cohen of Vanderbilt University. Deficient signaling of the EGFR and other receptor tyrosine kinases in humans is associated with diseases such as Alzheimer's, while over-expression is associated with the development of a wide variety of tumors. (Jun 2018). EGFR (The epidermal growth factor receptor; ErbB-1; HER1 in humans) is the cell-surface receptor for members of the epidermal growth factorfamily (EGF-family) of extracellular protein ligands. Epidermal growth factor receptor (EGFR, also known as ErbB-1 or HER-1) inhibitors are medicines that bind to certain parts of the EGFR and slow down or stop cell growth. Epidermal growth factor receptor has been shown to interact with: In fruitflies, the epidermal growth factor receptor interacts with Spitz.[99]. Patients have been divided into EGFR-positive and EGFR-negative, based upon whether a tissue test shows a mutation. [31], New drugs such as osimertinib, gefitinib, erlotinib and brigatinib directly target the EGFR. [18] In glioblastoma a specific mutation of EGFR, called EGFRvIII, is often observed. https://librepathology.org/w/index.php?title=Epidermal_growth_factor_receptor_inhibitors&oldid=50688. PMID 3039909. Cetuximab and panitumumab are examples of monoclonal antibody inhibitors. EGFR signaling is initiated by ligand binding to … ; Nakagawa, K.; Niho, S.; Lee, M.; Linke, R. et al. A single child displaying multi-organ epithelial inflammation was found to have a homozygous loss of function mutation in the EGFR gene. The epidermal growth factor receptor (EGFR) is among the most important targets in the treatment of advanced non-small cell lung cancer (NSCLC). DMSO 13 mg/mL: 10 mg: S1460: SP600125 Cohen shared the 1986 Nobel Prize in Medicine with Rita Levi-Montalcini for their discovery of growth factors. EGFR and lung cancer. 1m14: Tyrosine Kinase Domain from Epidermal Growth Factor Receptor, 1m17: Epidermal Growth Factor Receptor tyrosine kinase domain with 4-anilinoquinazoline inhibitor erlotinib, 1mox: Crystal Structure of Human Epidermal Growth Factor Receptor (residues 1-501) in complex with TGF-alpha. [20][21] However, its exact roles in these conditions are ill-defined. EGFR is a protein that is found on the surface of some cells that causes cells to divide when epidermal growth factor binds to it. [30], There are several quantitative methods available that use protein phosphorylation detection to identify EGFR family inhibitors. Another method is using small molecules to inhibit the EGFR tyrosine kinase, which is on the cytoplasmic side of the receptor. [17] These somatic mutations involving EGFR lead to its constant activation, which produces uncontrolled cell division. [9] This autophosphorylation elicits downstream activation and signaling by several other proteins that associate with the phosphorylated tyrosines through their own phosphotyrosine-binding SH2 domains. Yang, JC. (Jun 2018). Gefitinib (ZD1839) is a potent, selective and orally active EGFR tyrosine kinase inhibitor with an IC 50 of 33 nM. Erlotinib and gefitinib, two small molecules, are reversible EGFR tyrosine kinase inhibitors (TKIs). skin hypertrophic or keloid scars, liver cirrhosis, myocardial fibrosis, chronic kidney disease). What are EGFR inhibitors?. Einige Tyrosinkinase-Inhibitoren sind Medikamenten-Wirkstoffe, die bisher vor allem bei Tumorerkrankungen zum Einsatz kommen.

[14][15], Mutations that lead to EGFR overexpression (known as upregulation or amplification) have been associated with a number of cancers, including adenocarcinoma of the lung (40% of cases), anal cancers,[16] glioblastoma (50%) and epithelian tumors of the head and neck (80-100%). [10] Such proteins modulate phenotypes such as cell migration, adhesion, and proliferation. Many therapeutic approaches are aimed at the EGFR. EGFR-activating mutations are observed in approximately 15% to 20% of patients with non–small cell lung cancer. An interdisciplinary consensus on managing skin reactions associated with human epidermal growth factor receptor inhibitors. doi:10.1146/annurev.bi.56.070187.004313. Epidermal growth factor receptor (EGFR) inhibitors prevent cell growth and have shown benefit in the treatment of metastatic colorectal cancer, whether used as single agents or in combination with chemotherapy. CimaVax-EGF, an active vaccine targeting EGF as the major ligand of EGF, uses a different approach, raising antibodies against EGF itself, thereby denying EGFR-dependent cancers of a proliferative stimulus;[29] it is in use as a cancer therapy against non-small-cell lung carcinoma (the most common form of lung cancer) in Cuba, and is undergoing further trials for possible licensing in Japan, Europe, and the United States. Epidermal Growth Factor Receptor, EGFR, is a transmembrane tyrosine kinase that binds to the EGF-family of ligands. It activates several downstream signaling cascades, including MAPK, and leads to DNA synthesis and cell proliferation. Ostensibly by halting the signaling cascade in cells that rely on this pathway for growth, tumor proliferation and migration is diminished. The pathogenicity of the EGFR mutation was supported by in vitro experiments and functional analysis of a skin biopsy. The EGFR is essential for ductal development of the mammary glands,[11][12][13] and agonists of the EGFR such as amphiregulin, TGF-α, and heregulin induce both ductal and lobuloalveolar development even in the absence of estrogen and progesterone. Aberrant EGFR signaling has been implicated in psoriasis, eczema and atherosclerosis. As a result, autophosphorylation of several tyrosine (Y) residues in the C-terminal domain of EGFR occurs. EGFR (aka. T790M, also known as Thr790Met, is a gatekeeper mutation of the epidermal growth factor receptor (EGFR). EGFR-positive patients have shown a 60% response rate, which exceeds the response rate for conventional chemotherapy.[32]. ; Wu, YL. A hydrochloride acid salt form of Erlotinib which is a HER1/EGFR tyrosine kinase inhibitor for HER1/EGFR tyrosine kinase with an IC 50 of 2 nM. Tyrosinkinase-Inhibitoren sind Hemmstoffe, die verschiedene Enzyme aus der Gruppe der Tyrosinkinasen hemmen. The small molecule EGFR inhibitors, such as erlotinib, gefitinib and lapatinib, compete with ATP to bind the catalytic domain of the kinase which in turn inhibits EGFR autophosphorylation and downstream signaling. However the former is of the IgG1 type, the latter of the IgG2 type; consequences on antibody-dependent cellular cytotoxicity can be quite different. EGFR (aka. They work by inhibiting growth factor activity and controlling cell division. ; Cheng, Y.; Zhou, X.; Lee, KH. Tyrosine kinase inhibitors (TKIs) generally target proteins in the epidermal growth factor receptor (EGFR) family and have been developed as a cancer therapy that … From HemOnc.org - A Hematology Oncology Wiki. [8] – although there is some evidence that preformed inactive dimers may also exist before ligand binding. [33] In 10% to 15% of patients the effects can be serious and require treatment. "Afatinib versus cisplatin-based chemotherapy for EGFR mutation-positive lung adenocarcinoma (LUX-Lung 3 and LUX-Lung 6): analysis of overall survival data from two randomised, phase 3 trials.". Without kinase activity, EGFR is unable to activate itself, which is a prerequisite for binding of downstream adaptor proteins. [38], Imaging agents have been developed which identify EGFR-dependent cancers using labeled EGF. The first-line agent for treating EGFR mutant lung cancer is an FDA-approved medication called Tagrisso (osimertinib).11 Tagrisso is a tyrosine kinase inhibitor that blocks the activity of the EGFR protein. "Osimertinib for the treatment of patients with". Two primary sources of resistance are the T790M Mutation and MET oncogene. The epidermal growth factor receptor (EGFR) is a receptor tyrosine kinase of the ErbB family. effective when del19 is present. Tyrosine kinase inhibitors have provided an illustrative example of the successes in targeting oncogene addiction in cancer and the role of tumor-specific adaptations conferring therapeutic resistance. "Improvement in Overall Survival in a Randomized Study That Compared Dacomitinib With Gefitinib in Patients With Advanced Non-Small-Cell Lung Cancer and EGFR-Activating Mutations.". [28] Other monoclonals in clinical development are zalutumumab, nimotuzumab, and matuzumab. The EGFR gene provides instructions for making a receptor protein called the epidermal growth factor receptor, which spans the cell membrane so that one end of the protein remains inside the cell and the other end projects from the outer surface of the cell. [citation needed]. Erlotinib (an EGFR tyrosine kinase inhibitor) was the first … Upon activation by its growth factor ligands, EGFR undergoes a transition from an inactive monomeric form to an active homodimer. In many cancer types, mutations affecting EGFR expression or activity could result in cancer.[6]. These medications are referred to as tyrosine kinase inhibitors. However, these inhibitors are known to be effective in only a small subset of patients. Gefitinib selectively inhibits EGF-stimulated tumor cell growth (IC 50 of 54 nM) and that blocks EGF-stimulated EGFR autophosphorylation in tumor cells. More recently AstraZeneca has developed Osimertinib, a third generation tyrosine kinase inhibitor.[27]. The identification of EGFR as an oncogene has led to the development of anticancer therapeutics directed against EGFR (called "EGFR inhibitors"), including gefitinib,[25] erlotinib, afatinib, brigatinib and icotinib[26] for lung cancer, and cetuximab for colon cancer. Tyrosine kinase inhibitors directed against the epidermal growth factor receptor (EGFR) are the first molecular-targeted agents to be approved in the US and other countries for the treatment of advanced non-small-cell lung cancer after failure of chemotherapy. Recent studies show that inhibitors of the EGFR kinase will only be useful if the receptor plays a major role in the survival of the cancer or if the drug can be combined with other signal tranduction agents to cause certain cancer cells to kill themselves. Subcategories. Some patient characteristics, such as never-smoking, female gender, East Asian origin, adenocarcinoma histology, and bronchioloalveolar subtype, are associated with a greater benefit from treatment with EGFR inhibitors. (Feb 2015). 1ivo: Crystal Structure of the Complex of Human Epidermal Growth Factor and Receptor Extracellular Domains. Epidermal Growth Factor Receptor Inhibitors. EGFR inhibitors are used to treat colon cancer, skin cancer, lung cancer, and pancreatic cancer. EGFR-activating mutations are observed in approximately 15% to 20% of patients with non–small cell lung cancer. et al. Interruption of EGFR signalling, either by blocking EGFR binding sites on the extracellular domain of the receptor or by inhibiting intracellular tyrosine kinase activity, can prevent the growth of EGFR-expressing tumours and improve the patient's condition. Gefitinib also induces autophagy. Y… "Receptors for epidermal growth factor and other polypeptide mitogens". • Carpenter G (1987). ErbB1 or HER1) is a membranous receptor expressed in epithelial cells. [34][35], Some tests are aiming at predicting benefit from EGFR treatment, as Veristrat. DMSO 3 mg/mL: 100 mg: S1173: WZ4002: A novel mutant-selective EGFR kinase inhibitor of EGFR L858R and EGFR L858R/T790M with IC 50 s of 2 nM and 8 nM, respectively. They block the activity of the EGFR protein. Recently, studies have identi… EGFR Inhibitors. 4th Gen EGFR Inhibitor T790M mutation is the most common mechanism of resistance to first- and second-generation tyrosine kinase inhibitors (TKI) for epidermal growth factor receptor (EGFR). Afatinib (Gilotrif) - esp. Clin J Oncol Nurs. Epidermal growth factor receptor inhibitors, abbreviated EGFR inhibitors, is a class of drugs that blocks the EGF receptor. With the binding site blocked, signal molecules can no longer attach there and activate the tyrosine kinase. Alsharedi, M.; Bukamur, H.; Elhamdani, A. A protein kinase inhibitor is a type of enzyme inhibitor that blocks the action of one or more protein kinases.Protein kinases are enzymes that add a phosphate (PO 4) group to a protein, and can modulate its function.. A. Anti-EGFR antibodies; Pages in category "EGFR inhibitors" [5], The epidermal growth factor receptor is a member of the ErbB family of receptors, a subfamily of four closely related receptor tyrosine kinases: EGFR (ErbB-1), HER2/neu (ErbB-2), Her 3 (ErbB-3) and Her 4 (ErbB-4). Im medizinischen Sinne werden darunter chemische Substanzen verstanden, die speziell für die Hemmung von bestimmten Tyrosinkinasen … Epidermal growth factor receptor (EGFR) is a transmembrane protein that is activated by binding of its specific ligands, including epidermal growth factor and transforming growth factor α (TGFα)[7] ErbB2 has no known direct activating ligand, and may be in an activated state constitutively or become active upon heterodimerization with other family members such as EGFR. ... Ye et al. [19] Mutations, amplifications or misregulations of EGFR or family members are implicated in about 30% of all epithelial cancers. Epidermal Growth Factor Receptor, EGFR) ist ein Protein in Zellmembranen von Wirbeltieren; es ist der Rezeptor für den Epidermal-Growth-Factor (EGF) und ist ein Mitglied der ErbB-Familie, eine Unterfamilie von vier eng verwandten Rezeptor-Tyrosinkinasen: EGFR1/HER1 (ErbB-1), HER2/c-neu (ErbB-2), HER3 (ErbB-3) und HER4 (ErbB-4). 1IVO, 1M14, 1M17, 1MOX, 1NQL, 1XKK, 1YY9, 1Z9I, 2EB2, 2EB3, 2GS2, 2GS6, 2GS7, 2ITN, 2ITO, 2ITP, 2ITQ, 2ITT, 2ITU, 2ITV, 2ITW, 2ITY, 2ITZ, 2J5E, 2J5F, 2J6M, 2JIT, 2JIU, 2JIV, 2KS1, 2M0B, 2M20, 2RF9, 2RFD, 2RFE, 2RGP, 3B2U, 3B2V, 3BEL, 3BUO, 3C09, 3G5V, 3G5Y, 3GOP, 3GT8, 3IKA, 3LZB, 3NJP, 3OB2, 3OP0, 3P0Y, 3PFV, 3POZ, 3QWQ, 3UG1, 3UG2, 3VJN, 3VJO, 3VRP, 3VRR, 3W2O, 3W2P, 3W2Q, 3W2R, 3W2S, 3W32, 3W33, 4G5J, 4G5P, 4HJO, 4I1Z, 4I20, 4I21, 4I22, 4I23, 4I24, 4JQ7, 4JQ8, 4JR3, 4JRV, 4KRL, 4KRM, 4KRO, 4KRP, 4LI5, 4LL0, 4LQM, 4LRM, 4R3P, 4R3R, 4R5S, 4RIW, 4RIX, 4RIY, 4RJ4, 4RJ5, 4RJ6, 4RJ7, 4RJ8, 4TKS, 4WKQ, 4WRG, 4ZJV, 5CNN, 5CNO, 5CAN, 2N5S, 5CAL, 5C8M, 4UV7, 5CAV, 5CZI, 5EDQ, 5CAS, 5CAO, 5CAP, 5EM5, 5HG5, 5EDR, 5EM8, 5EDP, 5HG7, 5CAU, 5C8K, 5C8N, 5CZH, 5CAQ, 5EM6, 4UIP, 5HG9, 5EM7, 5HG8, 4ZSE, 5HIB, 5HIC, 5D41, 4WD5, The epidermal growth factor receptor (EGFR; ErbB-1; HER1 in humans) is a transmembrane protein that is a receptor for members of the epidermal growth factor family (EGF family) of extracellular protein ligands.
