Text-mined interactions from Literome
Cunnick et al., J Biol Chem 2002
(MAP Kinase Signaling System) :
Mek1 activation by
Gab1PH-SHP2DeltaN was
inhibited by an
Src inhibitor and by Csk ... Significantly,
Gab1PH-SHP2DeltaN induced
Src activation
Chan et al., J Biol Chem 2003
:
Increased expression of wild-type
Src enhanced HGF induced phosphorylation of
Gab1 , and, in contrast, expression of the Src kinase-deficient mutant or treatment of the specific Src inhibitor PP1 suppressed it ... Expression of a constitutively active Src mutant ( Y527F ) or oncogenic
v-Src led to a prominent increase in
Gab1 phosphorylation independent of HGF stimulation ... Taken together, our results establish a new
role for
Src in HGF induced
Gab1 phosphorylation
Ren et al., J Biol Chem 2004
:
Roles of
Gab1 and SHP2 in paxillin tyrosine dephosphorylation and
Src activation in response to epidermal growth factor ... Expression of an SHP2 binding defective mutant of
Gab1 ( Gab1FF ) or a catalytically inactive mutant of SHP2 ( SHP2DN )
prevented paxillin tyrosine dephosphorylation and
Src activation induced by EGF
Waters et al., Cell Signal 2005
:
This leads to a G
protein/c-Src dependent tyrosine phosphorylation of
Gab1 and accumulation of dynamin II at the plasma membrane, a step required for endocytosis of the PDGFbeta receptor-GPCR complex
Jin et al., J Biol Chem 2005
:
Gab1 phosphorylation as well as activation of Akt and eNOS by flow was inhibited by the Src kinase inhibitor PP2 ( 4-amino-5- ( 4-chlorophenyl ) -7- ( t-butyl ) pyrazolo [ 3,4-d ] pyrimidine ) and VEGFR2 kinase inhibitors SU1498 and VTI, suggesting that flow mediated
Gab1 phosphorylation is
Src kinase
dependent and VEGFR2 dependent
Watanabe et al., Mol Cancer Res 2009
(Sarcoma, Synovial) :
In response to hepatocyte growth factor stimulation, Crk prominently
induced the tyrosine phosphorylation of
Grb2 associated binder 1 through activation of
Src and focal adhesion kinase, and the Src family kinase inhibitor PP2 almost completely inhibited the proliferation of SYO-1 cells
