    basic FUNCTION
  • serine-threonine phosphatase activity
  • playing a role in specific sensory neuron function and/or development
  • PPEF1 plays a pivotal role in tumorigenesis of lung cancer cells by reducing PDCD5-mediated genotoxic stress responses

    small molecule metal binding,
  • Mg2+
  • Mn2+
  • protein
  • PPEF1 interacts with and dephosphorylates PDCD5 at Ser-119, which leads to PDCD5 destabilization
  • PPEF1 suppressed TP53-mediated genotoxic stress response via negative regulation of PDCD5
  • cell & other
    REGULATION
    Phosphorylated by CSNK2A1 at Ser119, which is required for nuclear translocation in response to genotoxic stress
    Other regulated by calcium
