Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0000209
UniProt IDO14977
Primary gene name(s)AZIN1
Synonym gene name(s)OAZI, OAZIN
Protein nameAntizyme inhibitor 1
Protein functionAntizyme inhibitor protein that positively regulates ornithine decarboxylase, ODC activity and polyamine uptake by counteracting the negative effect of antizyme OAZ1, OAZ2 and OAZ3 on ODC1 activity, PubMed:17900240. Inhibits antizyme-dependent ODC degradation by binding to antizymes. Releases ODC1 from its inactive complex with antizymes, leading to formation of the catalytically active ODC1. {ECO:0000269|PubMed:17900240}.
Subcellular locationNucleus {ECO:0000250}.
