NEIL2 (endonuclease VIII-like 2) is a mammalian DNA glycosylase belonging to the Nei-like (NEIL) family, which plays a critical role in base excision repair (BER) pathways. It primarily targets and repairs oxidatively damaged bases, such as 5-hydroxyuracil, formamidopyrimidines, and spiroiminodihydantoin lesions, formed by reactive oxygen species (ROS) or ionizing radiation. Unlike NEIL1 and NEIL3. NEIL2 exhibits a strong preference for single-stranded DNA and bubble structures, suggesting specialized roles in transcription-coupled repair and replication-associated repair processes. Structurally, NEIL2 contains a conserved helix-hairpin-helix motif for DNA binding and a [4Fe-4S] cluster involved in redox sensing.
Recombinant NEIL2 protein is produced through heterologous expression systems (e.g., E. coli or mammalian cells) for biochemical and functional studies. Researchers utilize purified NEIL2 to investigate its enzymatic kinetics, substrate specificity, and interactions with other BER proteins like DNA polymerase β and FEN1. Its role in maintaining genomic stability has been linked to cancer prevention, aging, and neurological disorders. Recent studies highlight NEIL2's involvement in immune regulation through epigenetic mechanisms and its potential as a therapeutic target for inflammation-related diseases. The development of recombinant NEIL2 has significantly advanced understanding of oxidative DNA damage repair mechanisms and their pathophysiological implications.
