SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytosolic
	intracellular,cytoplasm,cytoskeleton,microtubule,centrosome
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

INTERACTION

DNA

RNA

small molecule

protein	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)
