    text
  • dynamic protein that shuttles between the cytoplasm and the nucleus and functions in both compartments
  • nuclear accumulation of RPS3 results in an increase in DNA repair activity to some extent, thereby sustaining neuronal survival
  • basic FUNCTION
  • 40S ribosomal protein involved in the repair of
  • oxidative DNA lesions
  • having an extraribosomal role as an endonuclease involved in the repair of UV-induced DNA damage
  • involved in induction of apoptosis
  • functioning as a ribosomal protein but, in addition, may influence repair activities at sites of DNA damage
  • plays a role in repairing various DNA damage acting as a repair UV endonuclease
  • free RPS3 can regulates its own translation via a feedback mechanism
  • protecting against UV-induced skin cell death
  • 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
  • CELLULAR PROCESS cell life, cell death/apoptosis

    protein
  • multi-functional protein that interacts with both TP53 and MDM2 through its KH domain, acted as a scaffold for the additional binding of MDM2 and TP53, suggesting that it interacts with important proteins involved in maintaining genomic integrity (MID: 19656744)
  • 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

    REGULATION
    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
