Functioni

Ornithine decarboxylase (ODC) antizyme protein that negatively regulates ODC activity and intracellular polyamine biosynthesis and uptake by binding to and targeting ODC1 for degradation. 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 (By similarity).By similarity

Interactioni

Subunit structurei

Forms a ternary complex with PSMB4 and OAZ1 before PSMB4 is incorporated into the 20S proteasome. Interacts with AZIN2; the interaction stabilizes the complex by inhibiting AZIN2 ubiquitination and degradation and leads to increased ornithine decarboxylase (ODC) activity and decreased rate of ODC1 degradation (By similarity).By similarity

Sequence processingi: The displayed sequence is further processed into a mature form.

This entry describes 1 isoform i produced by ribosomal frameshifting. AlignAdd to basket

Note: A ribosomal frameshift occurs between the codons for Ser-68 and Asp-69. An autoregulatory mechanism enables modulation of frameshifting according to the cellular concentration of polyamines.
Isoform 1 (identifier: Q56K12-1) [UniParc]FASTAAdd to basket

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
