**Background of AZIN1 Recombinant Protein**
AZIN1 (Antizyme Inhibitor 1) is a regulatory protein involved in polyamine biosynthesis, a critical pathway for cell growth, proliferation, and differentiation. It functions as a positive regulator by counteracting the activity of antizymes (AZs), which are endogenous inhibitors of ornithine decarboxylase (ODC)—the rate-limiting enzyme in polyamine synthesis. AZIN1 binds to antizymes with high affinity, preventing their interaction with ODC and proteasomal degradation of ODC. This stabilization of ODC sustains polyamine production, essential for cellular processes like DNA replication and stress response.
The AZIN1 gene is highly conserved across species and expressed in various tissues, with elevated levels observed in rapidly dividing cells, including cancer cells. Dysregulation of AZIN1 has been linked to pathological conditions, such as tumor progression, neurodevelopmental disorders, and viral infections. Overexpression of AZIN1 is associated with increased polyamine levels, promoting cell proliferation and oncogenesis, while its downregulation may impair cellular homeostasis.
Recombinant AZIN1 protein is produced using expression systems (e.g., *E. coli* or mammalian cells) to study its structure, interactions, and functional mechanisms. It serves as a tool for investigating polyamine metabolism, cancer biology, and potential therapeutic targeting. Researchers also utilize AZIN1 recombinant protein in *in vitro* assays to screen for inhibitors or modulators of the polyamine pathway, aiming to develop treatments for cancers or other hyperproliferative diseases. Its role in cellular stress adaptation and viral replication further expands its relevance in biomedical research.
In summary, AZIN1 recombinant protein is pivotal for understanding polyamine-driven cellular dynamics and exploring therapeutic strategies against diseases linked to its dysregulation.
