text
  • mainly present in the cytosol
    • basic FUNCTION
  • rate-limiting enzyme of the polyamine biosynthesis pathway which catalyzes ornithine to putrescine
  • has no intrinsic arginine decarboxylase activity
  • having an antiapoptotic role for ornithine decarboxylase during oocyte maturation
  • dimeric enzyme involved in polyamine biosynthesis, and it catalyzes the decarboxylation of ornithine to putrescin
  • regulates the activity and localization of RHOA via polyamination
  • ODC1, OAZ1 and AZIN1 play a key role in regulation of intracellular polyamine levels by forming a regulatory circuit through their interactions
  • modifier of APC-dependent tumourigenesis
  • promotes myoblast proliferation and delays differentiation
  • both AMD1 and ODC1 are essential regulators of ESCs and function to ensure high polyamine levels to promote ESC self-renewal

    protein
  • OAZ1 is a positive regulator of ODC1, is homologous to ODC1, exists predominantly as a monomer and lacks decarboxylase activity
  • SPR is a novel regulator of ODC1 enzyme activity and, potentially SPR drives ODC1-mediated malignant progression in neuroblastoma
