  • polyribosome
    • basic FUNCTION
  • GTP-dependent translocation of the nascent protein
  • is a biochemical sensor that couples miniature synaptic events to local translational suppression in neuronal dendrites
  • intracellular target of diphtheria toxin is a modified histidine residue, diphthamide, in the translation elongation factor, EEF2
  • EEF2 phosphorylation state localized to the growth cone regulates potentially neurite outgrowth
  • EEF2 and RPS6KB1 signaling pathways control protein synthesis and are inhibited during myocardial ischemia
    • CELLULAR PROCESS protein, translation/synthesis
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
  • EEF2K/EEF2 pathway is a key biochemical sensor that couple neuronal activity to spine plasticity, by controlling the dendritic translation of BDNF
    • a component
    INTERACTION
    DNA
    RNA
    small molecule nucleotide,
    GTP
    protein
  • inactivation of EEF2K by CDK1 may serve to keep EEF2 active during mitosis (where calcium levels rise) and thereby permit protein synthesis to proceed in mitotic cells
  • TRPM7 via its kinase mediates enhanced Thr56 phosphorylation of EEF2
  • EIF5A is closely related to EEF2 function during translation elongation
  • PRKAA2 controls cardiac RPS6KB1 under normoxia and regulates EEF2 but not the MTOR-RPS6KB1 pathway during ischemia
  • substrate of CSK and could locate in the nucleus
  • upon activation, EEF2K phosphorylates and thereby inhibits EEF2, resulting in a dramatic reduction of mRNA translation
    • cell & other
    REGULATION
    Phosphorylated by CSK and CSK-mediated phosphorylation of EEF2 has no effect on its cytoplasmic function in regulating protein translation
