Protein-Protein interactions - manually collected from original source literature:
Studies that report less than 10 interactions are marked with *
Text-mined interactions from Literome
Tan et al., Proc Natl Acad Sci U S A 1999
:
Moreover, the coupling of NS5A to
Grb2 in these cells was
induced by
epidermal growth factor stimulation
Takeuchi et al., Am J Physiol 1999
:
Since Ras activation requires the assembly of a multiprotein complex, we examined the
effect of carbachol and
EGF on tyrosyl phosphorylation of Shc and its association with
Grb2 and the guanine nucleotide exchange factor Sos
Wang et al., J Biol Chem 1999
:
The tyrphostin AG1478, known to inhibit EGF receptor phosphorylation, also inhibited the angiotensin II and
EGF induced
activation of ERK, the phosphorylation of the EGF receptor, and the subsequent association of Shc and
Grb2 ... Nitric oxide did not affect either EGF receptor phosphorylation or
Shc-Grb2 activation
induced by either Ang II or
EGF
Katayama et al., Jpn J Cancer Res 1999
(Glioma) :
By contrast, Shc and
Grb2 were inducibly associated with the EGFR in
response to
EGF stimulation of glioma cells
Take et al., Biochem Biophys Res Commun 2000
:
Our results suggest that
CIN85 may
play a specific role in the
EGF receptor mediated signaling cascade via its interaction with c-Cbl
He et al., J Virol 2002
:
NS5A containing mutations within the C-terminal proline-rich motif neither bound
Grb2 nor
inhibited ERK1/2 activation by
EGF , demonstrating that NS5A-Grb2 binding and downstream effects were due to direct interactions
Kowanetz et al., J Biol Chem 2003
:
Identification of a novel proline-arginine motif involved in
CIN85 dependent clustering of Cbl and down-regulation of
epidermal growth factor receptors
Choi et al., Cell Signal 2005
:
Replacement of Tyr783 with Phe completely blocked
EGF induced interaction of PLC-gamma1 with
Grb2 , indicating that tyrosine phosphorylation of PLC-gamma1 at Tyr783 is essential for the interaction with Grb2
Gosens et al., Am J Physiol Lung Cell Mol Physiol 2007
:
EGF induced concomitant phosphorylation of caveolin-1 and p42/p44 MAP kinase ; however, EGF did not promote the localization of p42/p44 MAP kinase,
Grb2 , or Raf-1 to caveolae
Cao et al., Cancer Lett 2008
(Ovarian Neoplasms) :
Further studies showed that PD153035, which does not reverse ligand induced EGFR down-regulation, blocks
EGF induced EGFR activation as well as EGFR 's binding to c-cbl and
Grb2
Ayoub et al., PloS one 2013
:
Both
EGF and HRG
effects on
Grb2 interaction are dose dependent, and specifically blocked by EGFR inhibitor AG-1478 ... Furthermore, truncation of HER3 to remove the putative Grb2 binding sites appears to abolish
EGF induced
Grb2 recruitment to the EGFR-HER3 heteromer ... Our results support the concept that EGFR interacts with
Grb2 in both constitutive and
EGF dependent manners and this interaction is independent of HER3 co-expression
Polk et al., Gastroenterology 1995
:
EGF induced association of Shc with the
adapter protein Grb2 may have implications for activation of the p21ras signaling pathway in the intestine
Yamauchi et al., J Biol Chem 1995
(Carcinoma, Hepatocellular...) :
Further, activation of the
EGF receptor did not
result in any significant tyrosine phosphorylation of SHPTP2 and/or the association of the 115-kDa protein with
Grb2
Hashimoto et al., Oncogene 1994
:
Both NGF and
EGF induced rapid tyrosine phosphorylation of Shc and its association with both the receptors and with
Grb2/Ash
Ohmichi et al., J Biol Chem 1994
:
NGF and
EGF also
induced the association of Shc proteins with a Grb2 fusion protein or endogenous
Grb2 , whereas insulin had no effect
Tanaka et al., Mol Cell Biol 1995
:
In contrast to results with Abl, Erk activation by
EGF was strongly
inhibited only by
Grb2 mutants ; Crk and Nck mutants had little or no effect
Satoh et al., FEBS Lett 1996
:
Furthermore, we observed association of ACK with an adaptor protein Grb2, which may suggest the
involvement of
Grb2 in
EGF receptor mediated tyrosine phosphorylation of ACK
Wang et al., Science 1996
:
EGF stimulation of canine epithelial cells
induced a rapid and transient association of the SH3-SH2-SH3 protein
GRB2 with dynamin, a guanosine triphosphatase that regulates endocytosis
Wong et al., J Biol Chem 1996
:
Additional experiments indicated that neither the binding of the nucleotide exchange factor Sos to GRB2 nor tyrosine phosphorylation of PTP1D was required for
EGF stimulated coupling of PTP1D to
GRB2
Johnson et al., J Biol Chem 1996
:
Because Ras activation by
EGF involves EGF stimulated association of EGF-R with
Grb2 , the EGF-R was immunoprecipitated and a Western blot was probed for Grb2
Anafi et al., J Biol Chem 1997
:
Epidermal growth factor (EGF) stimulation did not
affect the binding of
Grb2 to HPK1 but induced recruitment of the Grb2.HPK1 complex to the autophosphorylated EGF receptor and to the Shc docking protein
Tiganis et al., Mol Cell Biol 1998
:
However, TC45 inhibited the
EGF induced association of p52Shc with
Grb2 , which was attributed to the ability of the PTP to recognize specifically p52Shc phosphorylated on Y239
Deb et al., J Biol Chem 1998
:
Dominant negative forms of SHP-2 had no effect on
EGF stimulated interaction of
GRB2 with EGFR or SHC, nor did they influence phosphorylation of SHC and SHC/EGFR association
Gresham et al., Int J Cancer 1998
(Prostatic Neoplasms) :
In all of the tumor cell lines,
EGF caused an association between Shc and
Grb2 , another adapter protein linked to cellular ras activation
