text
  • localize to centrosomes and modulate centrosome overproduction
  • basic FUNCTION
  • programming ribosomal frameshifting
  • modulating the rate of ODC1 degradation
  • catalyzing the conversion of ornithine to putrescine in the first and apparently rate-limiting step in polyamine biosynthesis, and playing a role in the regulation of polyamine synthesis (negative regulator of cellular polyamines)
  • can alter the intensity and duration of the BMP stimulus through SMAD6 and the tissue-specific expression of OAZ1 is a critical determinant of the cellular response to the BMP signal
  • ODC1, OAZ1 and AZIN1 play a key role in regulation of intracellular polyamine levels by forming a regulatory circuit through their interactions
  • inactivates ODC1 and targets it to ubiquitin-independent degradation by the 26S proteasome
  • mediator of ubiquitin-independent degradation and a suspected tumor suppressor
  • restrains the assembly of centrioles by controlling the levels of centrosomal TTK through the CDK2-regulated TTK degradation signal

  • SNIP1
  • interacting with AURKAIP1 (AURKAIP1, OAZ1 and Aurora-A could exist as a ternary complex and AURKAIP1 enhances the interaction between OAZ1 and Aurora-A)
  • positive regulator of ODC1 that is homologous to ODC1, exists predominantly as a monomer and lacks decarboxylase activity
  • exerts its effect on centrosomes via TTK (promotes the removal of TTK from centrosomes, and centrosome overproduction caused by reducing OAZ1 activity requires TTK)
