  • nuclear localization signal (NLS)located in the N-terminal domain with six C2H2 zinc fingers
  • an activation domain in the C-terminus (Wezensky 2010)

  • CATEGORY regulatory , transcription factor
    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • having transcription factor activity and functioning as a tumor suppressor in association with HIF1A
  • may be an oxidative stress responding regulator in lung cells
  • controls the stability of RCHY1, an E3 ubiquitin ligase for TP53
  • transcription factor of the surfactant protein C (SP-C) promoter (Yang 2009)
  • having a pathogenic role in pulmonary emphysema, a critical aspect of severe chronic obstructive pulmonary disease (Yang 2009)
  • regulate the pro-apoptotic factor, BNIP3, demonstrating that PLAGL2 may also function as a tumor suppressor (Wezensky 2010)
  • plays a role in the regulation of NCF2, the gene encoding the NADPH oxidase cytosolic protein NCF2, but not sufficient to activate an NCF2 promoter-reporter plasmid, suggesting the requirement for other factors (Wezensky 2010)
  • with MED15, and SPI1 cooperate to enhance NCF2 promoter-reporter activity (Wezensky 2010)
  • CELLULAR PROCESS nucleotide, transcription, regulation
    a component
    DNA binding
    small molecule metal binding,
  • Zn2+
  • protein
  • with HIF1A
  • interacting with UBE2I (functioned as a co-factor of PLAGL2 on the surfactant protein-C promoter and the co-activation was independent of its SUMOylation enzymatic activity)
  • direct binding of PLAGL2 to the NCF2 promoter sequence (Wezensky 2010)
  • interaction between PLAGL2 and MED15 (Wezensky 2010)
