EPHB2 — RAC3
Text-mined interactions from Literome
Nosaka et al., Biochem Biophys Res Commun 2001
(Fibrosarcoma) :
Rac is activated by tumor necrosis factor alpha and is
involved in activation of
Erk
Woo et al., J Biol Chem 2002
:
Consistent with those findings, leukotriene B ( 4 )
Rac-dependently stimulates ERK and cytosolic phospholipase A ( 2 ) activity, and transient transfection with plasmid expressing Rac ( V12 ), a constitutively activated Rac1 mutant, also dose-dependently
stimulates ERK activity
Arai et al., Oncogene 2002
:
A dominant negative
Rac mutant, Rac17N, also
inhibited the cytokine induced activation of
Erk as well as Elk-1
Woo et al., Mol Cells 2002
(MAP Kinase Signaling System) :
Our results showed that LPS induced the activation of
ERK and p38 MAP kinase in a
Rac dependent manner, suggesting a mediatory role of Rac1 in LPS signaling to MAPKs stimulation
Eblen et al., Mol Cell Biol 2002
(MAP Kinase Signaling System) :
Phosphorylation of
ERK2-delta19-25 but not of wild-type ERK2 in response to Ras V12 was greatly
inhibited by dominant negative
Rac ... Activated forms of
Rac and Cdc42 could
enhance the association of wild-type
ERK2 with MEK1 but not with MEK2 in serum starved adherent cells
Zhong et al., Blood 2003
(MAP Kinase Signaling System) :
Rac and Cdc42, but not Ras or Rho, were
responsible for this
MAPK/ERK activation ... We conclude from these data that
Rac/Cdc42 dependent
activation of
MAPK/ERK is a critical event in the immediate phagocytic response of PMNs to microbial challenge
Hammarberg et al., Biochem Pharmacol 2004
:
In addition, inhibition of
Rac/Cdc42 , small GTPases of the Rho family, by clostridium toxin B, diminished p38 phosphorylation but did not
affect ERK1/2
Eblen et al., Mol Cell Biol 2004
(MAP Kinase Signaling System) :
It was previously shown that
Rac-p21 activated kinase (PAK) signaling
regulated the physical association of MEK1 with
ERK2 through phosphorylation sites in the proline-rich sequence (PRS) of MEK1
Nishida et al., J Biol Chem 2005
:
Dominant negative
Rac inhibited angiotensin II-stimulated ROS production, JNK activation, and p38 MAPK activation but did not
affect ERK activation
Bruinsma et al., Proc Natl Acad Sci U S A 2007
(MAP Kinase Signaling System) :
Chimaerin and
Rac regulate cell number, adherens junctions, and
ERK MAP kinase signaling in the Drosophila eye
Notcovich et al., Exp Cell Res 2010
:
On the other hand, H1R induced ERK1/2 activation was inhibited by U73122 but not affected by C3 or beta2-chimaerin, suggesting that
ERK1/2 activation was dependent on PLC and
independent of RhoA or
Rac
Gest et al., BMC cancer 2013
(Breast Neoplasms...) :
Secondly, we investigated the
effects of
Rac3 inhibition on the expression and activation of related signaling molecules, including NF-?B and
ERK
Frost et al., Mol Cell Biol 1996
:
Although neither activated
Rac nor the PAKs
stimulate ERK2 activity, overexpression of either dominant negative Rac2 or the N-terminal regulatory domain of PAK1 inhibits Ras mediated activation of ERK2, suggesting a permissive role for Rac in the control of the ERK pathway
Miranti et al., Curr Biol 1998
:
This pathway may regulate multiple downstream events in hematopoietic cells, including
Rac induced lamellipodia formation, tyrosine phosphorylation of Cbl, and activation of JNK,
ERK2 and the phosphatidylinositol 3'-kinase regulated kinase Akt
