InnateDB Gene IDBG-102418 (OAZ3)
Protein Structure
UniProt Annotation
Function Ornithine decarboxylase (ODC) antizyme protein that negatively regulates ODC activity and intracellular polyamine biosynthesis and uptake by binding to ODC1 without promoting its degradation (PubMed:17900240). Stabilizes AZIN2 by interfering with its ubiquitination. Involved in the translocation of AZNI2 from ER-Golgi intermediate compartment (ERGIC) to the cytosol. Probably plays a key role in spermatogenesis by regulating the intracellular concentration of polyamines in haploid germ cells. {ECO:0000269PubMed:17900240}.
Subcellular Localization Nucleus. Cytoplasm {ECO:0000250}.
