Predicted to enable ornithine decarboxylase inhibitor activity. Predicted to be involved in positive regulation of intracellular protein transport and positive regulation of protein catabolic process. Predicted to act upstream of or within polyamine biosynthetic process. Predicted to be active in cytoplasm and nucleus. Human ortholog(s) of this gene implicated in coronary restenosis. Orthologous to human OAZ1 (ornithine decarboxylase antizyme 1).
