EIF4E — PI3
Text-mined interactions from Literome
Rao et al., J Biol Chem 1999
:
These findings demonstrate that 1 ) PI3-kinase dependent and independent mechanisms appear to be involved in PGF2alpha induced activation of ERK2 ; 2 ) PGF2alpha induced
eIF4E and 4E-BP1 phosphorylation appear to be
mediated by both ERK dependent and
PI3-kinase dependent rapamycin-sensitive mechanisms ; and 3 ) ERK dependent eIF4E phosphorylation but not PI3-kinase dependent p70 ( S6k ) activation correlates with PGF2alpha induced global protein synthesis and bFGF-2 expression in VSMC
Morley et al., Cell Signal 2003
:
However, a cell-permeable, specific inhibitor of Mnk1, CGP57380 and the
phosphatidylinositol-3-kinase (PI3-K) inhibitor, LY294002,
prevented eIF4E phosphorylation in 293 cells irrespective of SAPK2a expression
Prasad et al., Oncogene 2009
(Lymphoma, Mantle-Cell) :
Notably, ON 01910.Na suppressed eukaryotic translation initiation factor 4E ( eIF4E ) -mediated cyclin D1 mRNA translation, decreased levels of phosphorylated Akt, mammalian target of Rapamycin (mTOR) and eIF4E binding protein (eIF4E-BP), lowered the cap site binding activity of
eIF4E and directly
inhibited activity of
phosphatidylinositol-3 kinase (PI-3K)
Das et al., J Cell Physiol 2013
(MAP Kinase Signaling System) :
TGFß induced
PI 3 kinase dependent Mnk-1 activation is
necessary for Ser-209 phosphorylation of
eIF4E and mesangial cell hypertrophy ... Moreover, we conclude that TGFß induced noncanonical signaling circuit involving
PI 3 kinase
dependent Mnk-1 mediated phosphorylation of
eIF4E at Ser-209 is required to facilitate mesangial cell hypertrophy
