Phosphorylated ERK negatively regulates KSR1/B-Raf interaction downregulating signal transmission.
In restig cells ERK1/2 are localised in the cytoplasm due to binding to many cytoplasmic anchors or scaffold proteins.
MP1 specifically binds MEK1 and ERK1 but not MEK2 or ERK2. (Activation on late endosomes)

a_re498( Apoptosis  map ):
Direct phosphorylation of CASP9 by ERK2 sufficient to block CASP9 processing
in vitro, recombinant hCASP9 phosphorylated on T125 by cytosolic extract or ERK2
in Hela cells, interaction GST-CASP9 / ERK
in Hela or HEK293, CASP9 T125 phosphorylation by OA, consititutively active MEK1, EGF or TPA
CASP9 T125 phosphorylation by CCNB1:CDC2
comment: phosphorylation during mitosis, when nuclear envelope is broken down
CASP9 T125 phosphorylation by DYRK1A
CASP9 T125 phosphorylation by DYRK1A and p38


s_mpk1_re65( Survival  map ):
Mxi2 is a splicing isoform of P38. It directly interacts with ERK1/2. Mxi2 prolongs ERK activation (in the nucleus) by binding.
Mxi2 could suffice to promote the transport of ERK1/2 to the nucleus in the absence of further stimulation.
PMID:12697810 PMID:17255949
s_mpk1_re91( Survival  map ):
The rapid and efficient phosphorylation of Elk1 by ERKs is enabled by a direct interaction between the two proteins.
ELK1 is a nuclear P38 target.
ELK1 is a nuclear JNK target.
PMID:16393692 PMID:20506250 PMID:11274345
s_mpk1_re93( Survival  map ):
DUSP5 represents an inducible ERK-specific MKP and it functions as both a nuclear anchor and inactivator of ERK MODULE:MAPK map in mammalian cells.
s_mpk1_re95( Survival  map ):
MSK1 and MSK2 are potently activated (by phosphorylation) in vivo by ERK1/2 and P38 but not JNK. They are localised in the nucleus of quiescent and activated cells which suggest that they may preferentially phosphorylate nuclear substrates.
s_mpk1_re177( Survival  map ):
Phosphorylation by both ERKs and their downstream RSKs can stabilise the c-FOS protein for several hours. The combination of these phosphorylations allows c-FOS sustained activity.


s_mpk1_re119( Survival  map ):
A small fraction of both ERK and GSK3 is constitutively found in a protease-protected mitochondrial compartment. How this fraction of ERK and GSK3 enters mitochondria is an open question.
s_mpk1_re114( Survival  map ):
We postulate a model in which ERK activation inhibits GSK3 activity (by phosphorylation) its association to CYPD and CYPD phosphorylation (by GSK3) leading to PTP desensitisation.
s_s_mpk1_re114( Survival  map ):


s_mpk1_re29( Survival  map ):
Docking of activated ERK to the KSR1 scaffold negatively regulates the interaction between KSR1 and B-Raf.
s_mpk1_re36( Survival  map ):
Activation of ERK pathway caused the dissociation of the MP1/ERK1 complex.
MP1 constitutively binds MEK1 but releases ERK / MAPK  map after activation. This turnover could provide an amplification mechanism that translates low MEK activity into sustained ERK / MAPK  map activation in which MP1 continues to supply MEK1 with inactive ERK / MAPK  map for phosphorylation.
PMID:15547943 PMID:16227978
s_mpk1_re159:( Survival  map ) Any other mechanism of ERK activation not explicitly modelled.
s_mpk1_re32( Survival  map ):
Caspase9 is phosphorylated on Thr125 in a MEK1/2-dependent manner in vivo. Furthermore caspase9 is efficiently phosphorylated on Thr125 by ERK in vitro suggesting that it is targeted directly by ERK in vivo. This is one of the ways ERK plays its anti-apoptotic role.
s_mpk1_re65( Survival  map ):
Mxi2 is a splicing isoform of P38. It directly interacts with ERK1/2. Mxi2 prolongs ERK activation (in the nucleus) by binding.
Mxi2 could suffice to promote the transport of ERK1/2 to the nucleus in the absence of further stimulation.
PMID:12697810 PMID:17255949
s_mpk1_re83( Survival  map ):
Upon activation scaffold proteins serve as platforms in which ERK dimers are assembled forming complexes capable of interacting with and activating cognate cytoplasmic substrates.
s_mpk1_re84( Survival  map ):
Unlike many other scaffolds ERK1/2 do not dissociate from Sef1 upon stimulation and therefore nuclear translocation of the Sef1 anchored fraction of ERK1/2 molecules is blocked.
PMID:18775330 PMID:19565474
s_mpk1_re87( Survival  map ):
Beta-ARRESTIN prevents the translocation of ERK into the nucleus thereby reducing phosphorylation of nuclear substrates and consequently MODULE:MAPK map -dependent gene expression.
PMID:18775330 PMID:19091303
s_mpk1_re90( Survival  map ):
DUSP6 may capture activated ERK2 dephosphorylate it and anchor the inactive kinase in the cytoplasm.
s_mpk1_re109( Survival  map ):
ERK phosphorylates GSK3B to facilitate phosphorylation of GSK3B by p90RSK (RSK) which leads to the inactivation of GSK3B. GSK3B docking to ERK and phosphorylation by ERK are required for inhibition of beta-catenin (CTNNB1) ubiquitination and therefore for its stabilisation. ERK GSK3B and p90RSK (RSK) are in the same complex.
s_mpk1_re119( Survival  map ):
A small fraction of both ERK and GSK3 is constitutively found in a protease-protected mitochondrial compartment. How this fraction of ERK and GSK3 enters mitochondria is an open question.
s_mpk1_re165( Survival  map ):
MNKs are cytoplasmic targets of ERK and P38.
s_mpk1_re187( Survival  map ):
JNK pathway negatively regulates ERK pathway by uncoupling ERK activation from MEK via activation of JUN transcriptional activity.
A direct interaction between P38 and ERK has been proposed as a mechanism to inhibit ERK phosphorylation. AP-1 mediated gene expression inhibits ERK phosphorylation.
PMID:12738796 PMID:18039929
s_mpk1_re264( Survival  map ):
PDK1 is a PI3K target leading to activation of P70 (through phosphorylation) and subsequent cell growth.
P70 activation requires both ERK cascade and PI3K/AKT cascade at least in some cell types.
PMID:12040186 PMID:11940578 PMID:10601235 PMID:11431469
s_mpk1_re275( Survival  map ):
Sprouty is induced by activated ERK through phosphorylation on Tyr55. It positively regulates EGFR signalling by sequestering Cbl whereas it negatively regulates FGFR signalling by sequestering Grb2 from FSR2.
