    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,cytoplasm,cytosolic
    basic FUNCTION
  • playing a role in the cell cycle
  • can activate both the MAP kinase and JNK kinase pathways
  • activates IKappaB kinases and thus induces the nuclear production of NF-KappaB
  • promotes the production of TNF-alpha and IL-2 during T lymphocyte activation
  • regulates IL8 production, which is markedly reduced in presence of KSR2
  • required for TLR4 activation of the MEK/ERK pathway
  • able to activate NF-KappaB1 by stimulating proteasome-mediated proteolysis of NF-KappaB1/p105
  • may be an important mediator of intracellular mechanotransduction in mesenchymal stem cells
  • regulator of T helper cell lineage decisions and important functional role in the regulation of Th1 responses
  • functioning as a promoter of apoptosis in ischemia/reperfusion injury
  • inducing cell migration upon COX2 expression and Erk1/Erk2 activity
  • can phosphorylate histone H3 and thus induces cellular transformation through up-regulation of c-fos transcriptional activity
  • CELLULAR PROCESS cell cycle, checkpoint
    PHYSIOLOGICAL PROCESS
