  • ribosomal protein of the 40 S subunit, required for ribosome biogenesis extraribosomal
  • role of RPS3 as a molecular switch that accommodates apoptotic induction to DNA repair through Akt-mediated phosphorylation
  • may act upstream of caspase-3, most likely in the mitochondrial apoptotic pathway
  • RPS3 is recruited to the DISC and plays a critical role in both genotoxic stress and cytokine induced apoptosis
  • has multi-functions such as translation, DNA repair and apoptosis
  • acts as a microtubule associated protein (MAP) and regulates spindle dynamics during mitosis

  • physiological target of AKT1 kinase and a novel mediator of neuronal apoptosis (AKT1-dependent phosphorylation of RPS3 inhibited its proapoptotic function and perturbed its interaction with E2F1)
  • RPS3 appears to be recruited to the death-inducing signaling complex (DISC) to induce apoptosis by interacting TRADD in response to extracellular stresses
  • cell & other
    Other AKT1 phosphorylation governs RPS3 nuclear accumulation that in turn impairs its apoptotic function thereby promoting cell survival (
    arginine methylation of RPS3 plays a critical role in its import into the nucleolus, as well as in small subunit assembly of the ribosome
