AZIN2 (Antizyme Inhibitor 2): AZIN2 regulates the activity of ornithine decarboxylase, a key enzyme in polyamine biosynthesis which is important for cell growth and differentiation. It acts by inhibiting antizyme, which usually downregulates ornithine decarboxylase. Abnormalities in polyamine metabolism, potentially influenced by AZIN2, have been associated with cancer, as polyamines are critical for cell proliferation....
