Description

The epidermal growth factor receptor (EGFR) is one member of the ERBB family of transmembrane glycoprotein tyrosine receptor kinases (RTK). Binding of EGFR to its ligands induces conformational change that unmasks the dimerization interface in the extracellular domain of EGFR, leading to receptor homo- or heterodimerization at the cell surface. Dimerization of the extracellular regions of EGFR triggers additional conformational change of the cytoplasmic EGFR regions, enabling the kinase domains of two EGFR molecules to achieve the catalytically active conformation. Ligand activated EGFR dimers trans-autophosphorylate on tyrosine residues in the cytoplasmic tail of the receptor. Phosphorylated tyrosines serve as binding sites for the recruitment of signal transducers and activators of intracellular substrates, which then stimulate intracellular signal transduction cascades that are involved in regulating cellular proliferation, differentiation, and survival. Recruitment of complexes containing GRB2 and SOS1 to phosphorylated EGFR dimers either directly, through phosphotyrosine residues that serve as GRB2 docking sites, or indirectly, through SHC1 recruitment, promotes GDP to GTP exchange on RAS, resulting in the activation of RAF/MAP kinase cascade. Binding of complexes of GRB2 and GAB1 to phosphorylated EGFR dimers leads to formation of the active PI3K complex, conversion of PIP2 into PIP3, and activation of AKT signaling. Phospholipase C-gamma1 (PLCG1) can also be recruited directly, through EGFR phosphotyrosine residues that serve as PLCG1 docking sites, which leads to PLCG1 phosphorylation by EGFR and activation of DAG and IP3 signaling. EGFR signaling is downregulated by the action of ubiquitin ligase CBL. CBL binds directly to the phosphorylated EGFR dimer through the phosphotyrosine Y1045 in the C-tail of EGFR, and after CBL is phosphorylated by EGFR, it becomes active and ubiquitinates phosphorylated EGFR dimers, targeting them for degradation. For a recent review of EGFR signaling, please refer to Avraham and Yarden, 2011.

PIP3 activates AKT signalingPathwayREACT_75829 (Reactome) Signaling by AKT is one of the key outcomes of receptor tyrosine kinase (RTK) activation. AKT is activated by the cellular second messenger PIP3, a phospholipid that is generated by PI3K. In ustimulated cells, PI3K class IA enzymes reside in the cytosol as inactive heterodimers composed of p85 regulatory subunit and p110 catalytic subunit. In this complex, p85 stabilizes p110 while inhibiting its catalytic activity. Upon binding of extracellular ligands to RTKs, receptors dimerize and undergo autophosphorylation. The regulatory subunit of PI3K, p85, is recruited to phosphorylated cytosolic RTK domains either directly or indirectly, through adaptor proteins, leading to a conformational change in the PI3K IA heterodimer that relieves inhibition of the p110 catalytic subunit. Activated PI3K IA phosphorylates PIP2, converting it to PIP3; this reaction is negatively regulated by PTEN phosphatase. PIP3 recruits AKT to the plasma membrane, allowing TORC2 to phosphorylate a conserved serine residue of AKT. Phosphorylation of this serine induces a conformation change in AKT, exposing a conserved threonine residue that is then phosphorylated by PDPK1 (PDK1). Phosphorylation of both the threonine and the serine residue is required to fully activate AKT. The active AKT then dissociates from PIP3 and phosphorylates a number of cytosolic and nuclear proteins that play important roles in cell survival and metabolism. For a recent review of AKT signaling, please refer to Manning and Cantley, 2007.

REACT_115549 (Reactome) Association of EGFRvIII mutant with HSP90 chaperone protein and its co-chaperone CDC37 is necessary for the proper functioning of mutant EGFR.
REACT_115562 (Reactome) Recruitment of GRB2:SOS1 complex by SHC1 bound to phosphorylated dimers of EGFR cancer mutants has not been directly tested, but is assumed to happen in the same way it happens with the SHC1 bound to the phosphorylated homodimer of wild-type EGFR.
REACT_115604 (Reactome) Direct binding of GRB2:GAB1:PIK3R1 complex to phosphorylated homodimers of EGFR cancer mutants has not been tested. This complex is recruted to EGFR via GRB2 binding to phosphorylated tyrosine residues Y1068 and Y1086 (corresponding to Y1092 and Y1110, respectively, when counting from the first amino acid of the EGFR precursor, prior to cleavage of the 24-amino acid signal peptide at the N-terminus). Phosphorylation of Y1068 (i.e. Y1092) has been directly demonstrated in the following EGFR cancer mutants: EGFR L858R mutant (Sordella et al. 2004, Lynch et al. 2004, Greulich et al. 2005, Yang et al. 2006, Choi et al. 2007); EGFR G719S mutant (Greulich et al. 2005, Choi et al. 2007); EGFR L747_P753insS mutant (Sordella et al. 2004, Lynch et al. 2004, Choi et al. 2007); EGFR L747_A750delinsP (Greulich et al. 2005); EGFR L747_S752del mutant (Pao et al. 2004); EGFR L861Q mutant (Lee et al. 2006, Yang et al. 2006); EGFRvIII mutant (Huang et al. 2007); EGFR A289V mutant (Lee et al. 2006); EGFR G598V mutant (Lee et al. 2006); EGFR R108K mutant (Lee et al. 2006); EGFR T263P mutant (Lee et al. 2006); EGFR D770_N771insNPG mutant (Greulich et al. 2005, Xu et al. 2007); EGFR D770_N771insNPH mutant (Xu et al. 2007); EGFR V738_K739insKIPVAI mutant (Xu et al. 2007); EGFR M766_A767insASV mutant (Xu et al. 2007).
REACT_115609 (Reactome) Non-covalent (reversible) tyrosine kinase inhibitors (TKIs), erlotinib, gefitinib, lapatinib and vandetanib, selectively inhibit EGFR-stimulated tumor cell growth by blocking EGFR mutant autophosphorylation through competitive inhibition of ATP binding to the kinase domain. A number of EGFR kinase domain mutants and extracellular domain point mutants show increased senistivity to non-covalent TKIs compared with the wild-type EGFR. EGFR kinase domain mutants may be resistant to non-covalent TKIs due to primary or secondary mutations in the kinase domain that increase the affinity of the kinase domain for ATP, such as small insertions within exon 20, and substituion of threonine 790 with methionine (T790M).
REACT_115610 (Reactome) Upon dimerization, EGFRvIII mutants trans-autophosphorylate on tyrosine residues Y992, Y1068, Y0186, Y1143 and Y1173 while the tyrosine residue Y1045, a docking site for CBL, remains either unphosphorylated or hypophosphorylated, allowing EGFRvIII to activate downstream signaling cascades while escaping downregulation.
REACT_115614 (Reactome) CBL binds to phosphorylated tyrosine Y1045 residue of EGFR cancer mutants. Phosphorylation of Y1045 (corresponding to Y1069 when counting from the first amino acid of the EGFR precursor, prior to cleavage of the 24-amino acid signal peptide at the N-terminus) has been directly demonstrated in the following EGFR cancer mutants: EGFR L858R mutant (Greulich et al. 2005, Choi et al. 2007); EGFR G719S mutant (Sordella et al. 2004, Greulich et al. 1005, Choi et al. 2007); EGFR L747_P753delinsS mutant (Sordella et al. 2004, Choi et al. 2007); EGFR L747_A750delinsP mutant (Greulich et al. 2005); EGFR L861Q mutant (Choi et al. 2007); EGFR A289V mutant (Lee et al. 2006); EGFR G598V mutant (Lee et al. 2006); EGFR R108K mutant (Lee et al. 2006); EGFR D770_N771insNPG mutant (Greulich et al. 2005; Xu et al. 2007); EGFR V738_K739insKIPVAI mutant (Xu et al. 2007); EGFR M766_A767insASV mutant (Xu et al. 2007). Very little if any phosphorylation of Y1045 was shown in EGFR T263P mutant (Lee et al. 2006) and EGFR D770_N771insNPH mutant (Xu et al. 2007). Direct binding of CBL was demonstrated for the EGFR L858R mutant (Yang et al. 2006, Padron et al. 2007) and EGFR E746_A750del mutant (Padron et al. 2007). In EGFRvIII mutant, Y1045 (Y1069) is not phosphorylated (Han et al. 2006, Grandal et al. 2007). Han et al. detected no CBL binding to EGFRvIII mutant (Han et al. 2006), while Grandal et al. detected very little binding, which they explained by indirect recruitment of CBL to EGFRvIII through GRB2 (Grandal et al. 2007).
REACT_115623 (Reactome) Although ligand-responsive EGFR mutants dimerize spontaneously, dimerization is increased in the presence of EGF.
REACT_115627 (Reactome) Once recruited, PLC-gamma 1 is assumed to be phosphorylated by EGFR cancer mutants in the same way it is phosphorylated by the wild-type EGFR.
REACT_115732 (Reactome) Phosphorylated CBL does not ubiquitinate EGFR kinase domain mutants efficiently, which enables mutant proteins to escape degradation. There are indications that phosphorylated CBL shows decreased affinity for EGFR kinase domain mutants compared to wild-type EGFR proteins, and quickly dissociates, before ubiquitination is completed. This decreased affinity may be due to altered structure of EGFR kinase domain mutants or to the presence of the chaperone protein HSP90 in complex with the mutant protein. Weaker afinity for phosphorylated CBL was directly demonstrated for EGFR L858R mutant (Yang et al. 2006), and poor ubiquitination inspite of CBL binding was shown for EGFR L858R and EGFR E746_A750del mutants (Yang et al. 2006, Padron et al. 2007).
REACT_115741 (Reactome) Cetuximab binds to the extracellular domain of EGFR and blocks ligand binding, leading to receptor inactivation, internalization and degradation. Cetuximab is approved for combination therapy and monotherapy of metastatic colorectal cancer and advanced squamous cell carcinoma of head and neck in patients whose tumors over-express wild-type EGFR protein, usually due to amplification of EGFR gene.
REACT_115744 (Reactome) Covalent (irreversible) tyrosine kinase inhibitors (TKIs), pelitinib, WZ4002, HKI-272, canertinib and afatinib, form a covalent bond with the EGFR cysteine residue C397 and inhibit trans-autophosphorylation of mutants resistant to non-covalent TKIs. However, effective concentrations of covalent TKIs also inhibit wild type EGFR, resulting in severe side effects. Hence, covalent TKIs have not shown much promise as therapeutics.
REACT_115745 (Reactome) Tyrosine residue Y992, a docking site for PLC-gamma 1 (PLCG1), is phosphorylated in EGFR cancer mutants and expected to recruit PLC-gamma 1 in the same way as the wild-type EGFR receptor. Phosphorylation of Y992 (corresponding to Y1016 when counting from the first amino acid of the EGFR precursor, prior to cleavage of the 24-amino acid signal peptide at the N-terminus) has been directly demonstrated for the following EGFR cancer mutants: EGFR L858R mutant (Sordella et al. 2004, Choi et al. 2007); EGFR G719S mutant (Choi et al. 2007); EGFR L747_P753delinsS mutant (Sordella et al. 2004, Choi et ak, 2007); EGFR L861Q mutant (Choi et al. 2007); EGFRvIII mutant (Grandal et al. 2007); EGFR A289V mutant (Lee et al. 2006); EGFR D770_N771insNPG mutant (Xu et al. 2007); EGFR D770_N771insNPH mutant (Xu et al. 2007); EGFR V738_K739insKIPVAI mutant (Xu et al. 2007); EGFR M766_A767insASV mutant (Xu et al. 2007).
REACT_115768 (Reactome) EGFR kinase domain mutants need continuous association with HSP90 chaperone protein for proper functioning. CDC37 is a co-chaperone of HSP90 that acts as a scaffold and regulator of interaction between HSP90 and its protein kinase clients. CDC37 binds a protein kinase through its N-terminal domain and HSP90 through its C-terminal domain, arresting ATP-ase activity of HSP90 and enabling the loading of a client kinase. CDC37 is frequently over-expressed in cancers involving mutant kinases and acts as an oncogene (reviewed by Gray Jr. et al. 2008). Association of EGFR extracellular domain point mutants with HSP90 chaperone has not been tested.
REACT_115772 (Reactome) The cytoplasmic domain of EGFR contains tyrosine, serine and threonine phosphorylation sites. Activation of ligand-responsive EGFR mutants through spontaneous or EGF-induced dimerization results in trans-autophosphorylation of 5 tyrosine residues (Y992, Y1068, Y1086, Y1148 and Y1173), which enables constitutive receptor signaling as it provides specific binding sites for cytosolic target proteins involved in signal transduction (Zhang et al. 2006, Yun et al. 2007, Sordella et al. 2004, Lee et al. 2006). Tyrosine residue Y1045, involved in EGFR down-regulation, is usually phosphorylated in ligand-responsive EGFR mutants (Sordella et al. 2004, Lee et al. 2006). The exact phosphorylation pattern has not been examined for each mutant, but is assumed to closely follow, based on existing experimental evidence, the trans-autophosphorylation pattern of the wild-type EGFR.
REACT_115796 (Reactome) EGFR L858R mutant was shown to directly phosphorylate CBL on tyrosine residue Y371. Other EGFR cancer mutants with phosphorylation of tyrosine Y1045 (Y1069) are assumed to bind and phosphorylate CBL in a manner similar to the wild-type EGFR.
REACT_115809 (Reactome) SOS1 is the guanine nucleotide exchange factor (GEF) for RAS. SOS1, recruited by GRB2 bound to p-SHC1:p-EGFR mutants, is assumed to activate RAS nucleotide exchange from the inactive form (bound to GDP) to an active form (bound to GTP). Although this reaction has not been shown to occur directly for EGFR cancer mutants, activation of RAF/MAP kinase cascade, through detection of phosphorylated ERK1/2, has been demonstrated in cells expressing EGFR L858R mutant (Sordella et al. 2004, Paez et al. 2004, Shimamura et al. 2005), EGFR E746_A750 mutant (Sordella et al. 2004, Shimamura et al. 2005), EGFR L747_P753delinS mutant (Sordella et al. 2004), and EGFR E746_A750del;T790M double mutant (Shimamura et al. 2005).
REACT_115811 (Reactome) Ligand-responsive EGFR mutants are able to bind EGF and exhibit increased activity in the presence of EGF.
REACT_115841 (Reactome) Constitutive phosphorylation of SHC1 was directly demonstrated in cells expressing EGFR L858R mutant (Greulich et al. 2005). Other EGFR cancer mutants were not directly tested for their ability to phosphorylate SHC1, but are assumed to interact with SHC1 in the same way as the wild-type EGFR protein.
REACT_115865 (Reactome) Benzoquinoid ansamycins (geldanamycin, herbimycin, and geldanamycin derivatives 17-AAG, 17-DMAG and IPI-504) are antitumor antibiotics that inactivate HSP90 by binding to its substrate-binding pocket.
REACT_115884 (Reactome) The kinase activity of PI3K mediates the phosphorylation of PIP2 to form PIP3. It is assumed that EGFR cancer mutants induce PI3K/AKT signaling in a manner similar to wild-type EGFR. Phosphorylation of AKT on serine residue S473, and therby activation of PI3K/AKT signaling cascade, has been directly demonstrated in cells expressing the following EGFR cancer mutants: EGFR L858R mutant (Sordella et al. 2004, Paez et al. 2004, Greulich et al. 2005, Shimamura et al. 2005); EGFR G719S mutant (Greulich et al. 2005); EGFR E746_A750del mutant (Sordella et al. 2004, Shimamura et al. 2005); EGFR L747_P753insS mutant (Sordella et al. 2004); EGFR L747_A750delinsP mutant (Greulich et al. 2005); EGFR L861Q mutant (Lee et al. 2006); EGFR D770_N771insNPG mutant (Greulich et al. 2005, Xu et al. 2007); EGFR D770_N771insNPH mutant (Xu et al. 2007); EGFR V738_K739insKIPVAI mutant (Xu et al. 2007); EGFR M766_A767insASV mutant (Xu et al. 2007); EGFR E746_A750del;T790M double mutant (Shimamura et al. 2005).
REACT_115887 (Reactome) EGFRvIII mutant lacks the ligand binding domain and is therefore unable to bind EGFR ligands, but is able to dimerize spontaneously. Self-dimerization may be dependent on N-linked glycosylation.
REACT_115903 (Reactome) Once phosphorylated, PLC-gamma 1 is expected to dissociate from phosphorylated EGFR cancer mutants and induce downstream signaling in the same way it does when activated by the wild-type EGFR. However, except for the phosphorylation of PLCG1 binding site in EGFR cancer mutants, other events involved in activation of PLCG1 signaling have not been studied in cells expressing EGFR cancer mutants.
REACT_115980 (Reactome) EGFR ligand-responsive mutants dimerize spontaneously, without ligand binding, although ligand binding ability is preserved. This was experimentally demonstrated for EFGR L858R mutant and is presumed to happen in other constitutively active EGFR kinase domain mutants and EGFR extracellular domain point mutants.
REACT_116004 (Reactome) The 110 kDa catalytic subunit of PI3K (PIK3CA) binds to the 85 kDa regulatory subunit of PI3K (PIK3R1) to create the active PI3K. EGFR cancer mutants are assumed to mediate the assembly of active PI3K in a manner similar to wild-type EGFR.
REACT_116063 (Reactome) SHC1 (Src homology 2 domain-containing transforming protein) is known to bind two phosphorylated tyrosine docking sites of EGFR: Y1148 and Y1173 (corresponding to Y1172 and Y1197 when counting from the first amino acid of EGFR precursor, before the cleavage of the 24-amino acid signal peptide at the N-terminus takes place). Phosphorylation of Y1173 tyrosine residue was directly demonstrated in the following EGFR cancer mutants: EGFR L858R mutant (Sordella et al. 2004, Greulich et al. 2005); EGFR G719S mutant (Greulich et al. 2005); EGFR L747_P753delinsS mutant (Sordella et al. 2004); EGFR L747_A750delinsP (Greulich et al. 2005); EGFRvIII mutant (Han et al. 2006, Grandal et al. 2007); EGFR D770_N771insNPG mutant (Greulich et al. 2005, Xu et al. 2007); EGFR D770_N771insNPH mutant (Xu et al. 2007); EGFR V738_K739insKIPVAI mutant (Xu et al. 2007); EGFR M766_A767insASV mutant (Xu et al. 2007). Phosphorylation of Y1148 was shown in EGFRvIII mutant (Huang et al. 2007).
Besides EGFR L858R mutant, which was directly shown to bind SHC1 (Greulich et al. 2005), binding of SHC1 was not tested in other EGFR cancer mutants. Nonetheless, it is assumed that SHC1 binds EGFR cancer mutants in the same way it binds wild-type EGFR.
REACT_116096 (Reactome) Covalent (irreversible) TKIs, pelitinib, WZ4002, HKI-272, canertinib and afatinib, inhibit the wild-type EGFR through formation of the covalent bond with the cysteine residue C397.
REACT_116141 (Reactome) Direct binding of GRB2:SOS1 complex to phosphorylated homodimers of EGFR cancer mutants has not been tested. GRB2 binds to phosphorylated tyrosine residues Y1068 and Y1086 (corresponding to Y1092 and Y1110, respectively, when counting from the first amino acid of the EGFR precursor, prior to cleavage of the 24-amino acid signal peptide at the N-terminus). Phosphorylation of Y1068 (i.e. Y1092) has been directly demonstrated in the following EGFR cancer mutants: EGFR L858R mutant (Sordella et al. 2004, Lynch et al. 2004, Greulich et al. 2005, Yang et al. 2006, Choi et al. 2007); EGFR G719S mutant (Greulich et al. 2005, Choi et al. 2007); EGFR L747_P753insS mutant (Sordella et al. 2004, Lynch et al. 2004, Choi et al. 2007); EGFR L747_A750delinsP (Greulich et al. 2005); EGFR L747_S752del mutant (Pao et al. 2004); EGFR L861Q mutant (Lee et al. 2006, Yang et al. 2006); EGFRvIII mutant (Huang et al. 2007); EGFR A289V mutant (Lee et al. 2006); EGFR G598V mutant (Lee et al. 2006); EGFR R108K mutant (Lee et al. 2006); EGFR T263P mutant (Lee et al. 2006); EGFR D770_N771insNPG mutant (Greulich et al. 2005, Xu et al. 2007); EGFR D770_N771insNPH mutant (Xu et al. 2007); EGFR V738_K739insKIPVAI mutant (Xu et al. 2007); EGFR M766_A767insASV mutant (Xu et al. 2007).
REACT_116154 (Reactome) Based on the wild-type EGFR signaling, it is assumed that the guanine nucleotide exchange factor SOS1 interacts with phosphorylated EGFR mutants through the adaptor protein, GRB2. Upon formation of this complex, SOS1 activates RAS by promoting GDP release and GTP binding. Although this reaction has not been directly confirmed for EGFR cancer mutants, activation of RAF/MAP kinase cascade has been demonstrated, through detection of phosphorylated ERK1/2, in cells expressing EGFR L858R mutant (Sordella et al. 2004, Paez et al. 2004, Shimamura et al. 2005), EGFR E746_A750del mutant (Sordella et al. 2004, Shimamura et al. 2005), EGFR L747_P753delinsS mutant (Sordella et al. 2004) and EGFR E746_A750del;T790M double mutant (Shimamura et al. 2005).
REACT_12381 (Reactome) Sprouty is ubiquitinated by CBL in an EGF-dependent manner. EGF stimulation induces the tyrosine phosphorylation of Sprouty, which in turn enhances the interaction of Sprouty with CBL. The CBL-mediated ubiquitination of Sprouty targets the protein for degradation by the 26S proteasome.
REACT_12386 (Reactome) The guanine nucleotide exchange factor SOS1 interacts with EGFR through the adaptor protein, GRB2. Upon formation of this complex, SOS activates RAS by promoting GDP release and GTP binding.
REACT_12387 (Reactome) Sprouty can constitutively interact with two SH3 domains of CIN85 whereas the third SH3 domain of CIN85 can still associate with CBL on cell activation with EGF. This allows Sprouty to block CIN85-mediated clustering of CBL molecules, stablization of CBL-EGFR interactions and efficient ubiquitination and down-regulation of EGFR.
REACT_12390 (Reactome) Dephosphorylation of CBP/PAG negatively regulates the recruitment of the Src inhibiting kinase, Csk. Src is not negatively regulated by phosphorylation by Csk.
REACT_12392 (Reactome) Cytoplasmic target proteins containing the SH2 domain can bind to activated EGFR. One such protein, growth factor receptor-bound protein 2 (GRB2), can bind activated EGFR with its SH2 domain whilst in complex with SOS through its SH3 domain. GRB2 can bind at either Y1068 and/or Y1086 tyrosine autophosphorylation sites on the receptor.
REACT_12401 (Reactome) Inactive phospholipase C-gamma1 (PLCG1) binds to activated epidermal growth factor receptor (EGFR).
REACT_12402 (Reactome) SOS1 is the guanine nucleotide exchange factor (GEF) for RAS. SOS1 activates RAS nucleotide exchange from the inactive form (bound to GDP) to an active form (bound to GTP).
REACT_12407 (Reactome) Once activated PLC-gamma1 dissociates from EGFR, it can hydrolyze PIP2.
REACT_12412 (Reactome) High concentrations of active CDC42 and Beta-Pix may promote the binding of Beta-Pix to CBL, pushing out the usually preferred binding partner CIN85 from the CBL complex. This competitive mechanism could block the CIN85-imposed clustering phenomenon on CBL that is required for tighter binding.
REACT_12423 (Reactome) GAB1 binds to EGF receptors via tyrosine autophosphorylation sites on the receptor.
REACT_12424 (Reactome) EGF (and indeed FGF, PDGF and NGF) stimulation results in CBL phosphorylation on Tyr-371. Phosphorylation is necessary for CBL to exhibit ubiquitin ligase activity.
REACT_12425 (Reactome) The regulatory subunit of PIK3 mediates the association of GAB1 and receptor protein-tyrosine kinases such as the EGF receptor, which can phosphorylate GAB1. It appears that the PIK3 regulatory subunit acts as an adaptor protein allowing GAB1 to serve as a substrate for several tyrosine kinases.
REACT_12432 (Reactome) Sprouty is ubiquitinated by CBL in an EGF-dependent manner. EGF stimulation induces the tyrosine phosphorylation of Sprouty, which in turn enhances the interaction of Sprouty with CBL.The CBL-mediated ubiquitination of Sprouty targets the protein for degradation by the 26S proteosome.
REACT_12441 (Reactome) The NEYTEG motif is very similar to the CBL binding motif around Tyr-1045 in EGFR. Tyrosine-phosphorylated Sprouty (hSpry) binds to CBL, which then cannot ubiquitinate EGFR. Sprouty acts as a decoy to lure CBL away from EGFR and targets it for degradation.
REACT_12451 (Reactome) Beta-Pix (Cool-1) associates with CBL, which appears to be a critical step in CDC42-mediated inhibition of EGFR ubiquitylation and downregulation. The SH3 domain of Beta-Pix specifically interacts with a proline-arginine motif (PxxxPR) present within CBL, which mediates ubiquitylation and subsequent degradation of Beta-Pix.
REACT_12465 (Reactome) Activated CDC42 binds to Beta-Pix (p85Cool-1), a protein that directly associates with CBL. This inhibits the binding of CBL to the EGF receptor and thus prevents CBL from catalyzing receptor ubiquitination.
REACT_12466 (Reactome) The SH2 domains repress phosphatase activity of SHP2. Binding of these domains to phosphotyrosine-containing proteins relieves this autoinhibition, possibly by inducing a conformational change in the enzyme.
REACT_12490 (Reactome) EGFR kinase phosphorylates the phosphorylation sites tyrosine 627 and 659 on GAB1
REACT_12491 (Reactome) EGF (and indeed FGF, PDGF and NGF) stimulation results in CBL phosphorylation on Tyr-371. Phosphorylation is necessary for CBL to exhibit ubiquitin ligase activity.
REACT_12495 (Reactome) Epsin directly modifies membrane curvature on binding to PIP2 in conjunction with clathrin polymerization.
REACT_12500 (Reactome) The NEYTEG motif is very similar to the CBL binding motif around Tyr-1045 in EGFR. Tyrosine-phosphorylated Sprouty (hSpry) binds to CBL, which then cannot ubiquitinate EGFR. Sprouty acts as a decoy to lure CBL away from EGFR and targets it for degradation.
REACT_12501 (Reactome) The 110 kDa catalytic subunit (PIK3CA) binds to the 85 kDa regulatory subunit (PIK3R1) to create the active PIK3.
REACT_12514 (Reactome) The tyrosine sites on SHC1 become possible binding sites for the GRB2:SOS1 complex.
REACT_12515 (Reactome) CBL down-regulates receptor tyrosine kinases by conjugating ubiquitin to them. This leads to receptor internalization and degradation. The ubiquitin protein ligase activity of CBL (abbreviated as E3 activity) is mediated by its RING finger domain.
REACT_12520 (Reactome) The adaptor protein CIN85 is monoubiquitinated by CBL after EGF stimulation. Monoubiquitination is thought to regulate receptor internalization and endosomal sorting.
REACT_12521 (Reactome) CBl-CIN85-Endophilin complex mediates ligand-induced down-regulation of the EGF receptor. The BAR domain of endophilin induces membrane curvature. The three SH3 domains of CIN85 bind to atypical proline-arginine motifs (PxxxPR) present in the carboxyl termini of CBL and CBL-b. In this way, CIN85 clusters CBL molecules, which is crucial for efficient EGFR endocytosis and degradation.
REACT_12527 (Reactome) At higher concentrations of ligand, a substantial fraction of the receptor (>50%) is endocytosed through a clathrin independent, lipid-raft-dependent route as the receptor becomes Y1045 phosphorylated and ubiquitnated. Eps15 and Epsin are found in caveolae. Eps15 and Epsin are immunoprecipated with the EGF receptor. Non-clathrin internalization of ubiquitinated EGFR depends on its interaction with proteins harbouring the UIM Ub-interacting motif, as shown through the ablation of three Ub-interacting motif-containing proteins, Eps15, Eps15R and Epsin.
REACT_12534 (Reactome) The pleckstrin homology (PH) domain of GAB1 binds to PIP3 and can target GAB1 to the plasma membrane in response to EGF stimulation. This mechanism provides a positive feedback loop with respect to PI3K activation, to enhance EGFR signalling.
REACT_12535 (Reactome) GRB2 (Growth factor receptor-bound protein 2) binds to GAB1 (GRB2-associated binding protein 1).
REACT_12562 (Reactome) CBL down-regulates receptor tyrosine kinases by conjugating ubiquitin to them. This leads to receptor internalization and degradation. The ubiquitin protein ligase activity of CBL (abbreviated as E3 activity) is mediated by its RING finger domain.
REACT_12569 (Reactome) EGFR phosphorylates PLC-gamma1, thus activating it.
REACT_12580 (Reactome) SHC1 (Src homology 2 domain-containing) transforming protein can bind to either tyrosine 1148 and/or tyrosine 1173 sites on the EGF receptor.
REACT_12592 (Reactome) Once bound to EGFR, SHC1 is phosphorylated on two tyrosines (Y349, Y350).
REACT_12601 (Reactome) SHP2 can dephosphorylate paxillin, which leads to Csk dissociation from the paxillin-Src complex and Src activation. Src is an SHP2 effector in EGF-stimulated Erk activation and cell migration.
REACT_12605 (Reactome) Phosphorylated GAB1 can bind PI3 kinase by its regulatory alpha subunit. SHP2 dephosphorylation of the tyrosine residues 447, 472 and 589 on GAB1 means PI3 kinase can no longer bind to the complex in the plasma membrane and cannot be activated.
REACT_12616 (Reactome) The Src homology 2 (SH2) domain of the phosphatidylinositol 3-kinase (PIK3) regulatory subunit (PIK3R1, i.e. PI3Kp85) binds to GAB1 in a phosphorylation-independent manner. GAB1 serves as a docking protein which recruits a number of downstream signalling proteins. PIK3R1 can bind to either GAB1 or phosphorylated GAB1.
REACT_12626 (Reactome) Upon EGF stimulation and consequent EGFR phosphorylation, GRB2 binds phosphorylated tyrosines
REACT_12629 (Reactome) The tyrosine-protein phosphatase SHP2 is a positive effector of EGFR signalling. SHP2 inhibits the tyrosine-dependent translocation of RasGAP (catalyses Ras inactivation) to the plasma membrane, thereby keeping it away from Ras-GTP (its substrate). This inhibition is achieved by the dephosphorylation of a RasGAP binding site on the EGF receptor.
REACT_12632 (Reactome) Phosphorylation at tyrosine Y1045 of EGFR creates a major docking site for E3 ubiquitin-protein ligase, CBL (Casitas B-lineage lymphoma proto- oncogene) and is required to sort the EGFR to lysosomes for degradation. The E3 ligase CBL plays a crucial role in these events as it dually participates in early events of internalization via a CIN85-endophilin dependent mechanism and endocytic sorting by mediating multiple monoubiquitylation of the receptor.
REACT_12635 (Reactome) CBL binds multiple signalling proteins including GRB2. The CBL:GRB2 complex translocates to the plasma membrane where it can bind to GRB2-specific docking sites on the EGF receptor.
REACT_12636 (Reactome) The kinase activity of PIK3 mediates the phosphorylation of PIP2 to form PIP3
REACT_2257 (Reactome) In the cytoplasm of unstimulated cells, SOS1 is found in a complex with GRB2. The interaction occurs between the carboxy terminal domain of SOS1 and the Src homology 3 (SH3) domains of GRB2.
REACT_9388 (Reactome) The cytoplasmic domain of EGFR contains tyrosine, serine and threonine phosphorylation sites. Dimerization of EGFR activates its intrinsic protein kinase activity and results in autophosphorylation of 6 tyrosine residues in the cytoplasmic tail of EGFR. Tyrosine autophosphorylation is crucial for normal receptor signalling. Five of these tyrosine residues (Y992, Y1068, Y1086, Y1148 and Y1173) serve as specific binding sites for cytosolic target proteins involved in signal transmission, while the tyrosine residue Y1045 is involved in recruitment of CBL ubiquitin ligase and downregulation of EGFR signaling through degradation of activated EGFR.
REACT_9397 (Reactome) EGF and other growth factors induce oligomerization of their specific receptors. Inactive EGFR monomers are in equilibrium with active EGFR dimers and binding of the EGF ligand stabilizes the active dimeric form.
REACT_9401 (Reactome) Besides autophosphorylation, EGFR can become tyrosine-phosphorylated by the action of the proto-oncogene tyrosine-protein kinase, c-src. This Src homology 2 (SH2) domain-containing protein is one of many such proteins which bind to phosphorylated sites on EGFR to affect signal transmission into the cell.
REACT_9423 (Reactome) Ligands of the epidermal growth factor receptor (EGFR) are shed from the plasma membrane by metalloproteases. Identification of the sheddases for EGFR ligands using mouse embryonic cells lacking candidate sheddases (a disintegrin and metalloprotease; ADAM) has revealed that ADAM10, -12 and -17 are the sheddases of the EGFR ligands in response to various shedding stimulants such as GPCR agonists, growth factors, cytokines, osmotic stress, wounding and phorbol ester. Among the EGFR ligands, heparin-binding EGF-like growth factor (HB-EGF), EGF and TGF-alpha are the best characterized.
REACT_9481 (Reactome) The prototypic receptor tyrosine kinase (RTK) EGFR is composed of 3 major domains; an extracellular domain linked via a single membrane-spanning domain to a cytoplasmic domain. EGF binds to the extracellular domain from where the signal is transmitted to the cytoplasmic domain.
