Function
[OAZ1_HUMAN] Ornithine decarboxylase (ODC) antizyme protein that negatively regulates ODC activity and intracellular polyamine biosynthesis and uptake by binding to and targeting ODC1 for degradation (PubMed:17900240). Stabilizes AZIN2 by interfering with its ubiquitination. Also inhibits cellular uptake of polyamines by inactivating the polyamine uptake transporter. SMAD1/OAZ1/PSMB4 complex mediates the degradation of the CREBBP/EP300 repressor SNIP1. Involved in the translocation of AZNI2 from ER-Golgi intermediate compartment (ERGIC) to the cytosol.[1] [2]
