背景信息

The ENOX2 protein, also known as tumor-associated NADH oxidase (tNOX), is a member of the ECTO-NOX family of oxidoreductases involved in cell growth regulation. Initially identified for its elevated expression in cancer cells, ENOX2 catalyzes the oxidation of NADH and reduction of extracellular electron acceptors, generating reactive oxygen species (ROS) that promote cell proliferation. Unlike its constitutive counterpart ENOX1. ENOX2 exhibits tumor-specific activity and is linked to the uncontrolled growth of malignant cells.

Structurally, ENOX2 contains conserved coenzyme Q-binding domains and a cysteine-rich motif critical for its enzymatic function. Its recombinant form is typically produced through heterologous expression systems (e.g., E. coli or mammalian cells) for research and therapeutic applications. Recombinant ENOX2 enables detailed study of its role in cancer metabolism, particularly in sustaining the "Warburg effect" - the metabolic shift favoring glycolysis even under aerobic conditions.

Current research focuses on ENOX2 as a potential therapeutic target. Its cancer-specific expression pattern makes it attractive for developing targeted therapies, with studies exploring small-molecule inhibitors and antibody-based approaches. Recombinant ENOX2 proteins are also used to screen anticancer compounds and develop diagnostic biomarkers. Challenges remain in understanding its precise molecular interactions and optimizing recombinant versions for stability in biotechnological applications. Ongoing investigations aim to elucidate its full regulatory network and explore its potential in personalized oncology.
