**Background of NEIL3 Recombinant Protein**
NEIL3 (endonuclease VIII-like 3) is a DNA glycosylase belonging to the NEIL family, which plays a critical role in base excision repair (BER), a pathway dedicated to repairing oxidized or alkylated DNA bases. Unlike its homologs NEIL1 and NEIL2. NEIL3 exhibits unique substrate specificity and functional versatility. It preferentially repairs bulky DNA lesions, such as spiroiminodihydantoin (Sp) and guanine hydantoin (Gh), formed under oxidative stress, and is particularly adept at addressing DNA damage in complex structural contexts, including single-stranded DNA and replication forks.
NEIL3 is highly expressed in proliferating cells, especially during the S phase of the cell cycle, and is implicated in maintaining genomic stability during DNA replication. Its role extends beyond canonical BER; recent studies suggest involvement in resolving interstrand crosslinks and supporting telomere integrity. Structurally, NEIL3 contains a conserved helix-hairpin-helix domain for substrate recognition and a unique C-terminal domain that may regulate protein-protein interactions or subcellular localization.
Recombinant NEIL3 protein is produced using heterologous expression systems (e.g., *E. coli* or mammalian cells*) to study its enzymatic activity, substrate preferences, and interactions with other repair proteins like PCNA or Pol β. Its recombinant form enables detailed biochemical assays, structural studies (e.g., crystallography or cryo-EM), and functional analyses in cellular models. Research on NEIL3 has gained momentum due to its potential links to cancer, neurodegeneration, and aging, where defective repair of oxidative DNA damage contributes to disease progression.
Overall, NEIL3 recombinant protein serves as a vital tool for dissecting DNA repair mechanisms and exploring therapeutic strategies targeting replication-associated genomic instability.
