**Background of Recombinant Human EEPD1 Protein**
Recombinant human EEPD1 (Endonuclease/Exonuclease/Phosphatase Domain-containing 1) is a genetically engineered protein derived from the human *EEPD1* gene. EEPD1 belongs to a conserved protein family characterized by a unique combination of endonuclease, exonuclease, and phosphatase domains, suggesting roles in nucleic acid metabolism or repair. Structurally, it contains an N-terminal phosphatase domain and a C-terminal DNA-binding region, which may enable interaction with DNA or RNA substrates.
Functionally, EEPD1 is implicated in maintaining genome stability, particularly in response to replication stress. Studies suggest it participates in resolving stalled replication forks, potentially through its nuclease activity, to prevent DNA damage accumulation. EEPD1 also interacts with key repair proteins like BRCA1 and RAD51. indicating a role in homologous recombination repair. Additionally, it may regulate cell cycle checkpoints, ensuring proper DNA replication before cell division.
Research using recombinant EEPD1 has focused on elucidating its enzymatic mechanisms, substrate specificity, and involvement in DNA repair pathways. Its dysregulation has been linked to cancer, where altered expression correlates with genomic instability or therapeutic resistance. Recombinant EEPD1 serves as a vital tool for in vitro studies, structural analysis, and drug discovery targeting DNA repair deficiencies.
Overall, EEPD1 represents a promising target for understanding genome maintenance and developing therapies for diseases linked to replication stress or DNA damage. Further studies are needed to fully unravel its physiological and pathological roles.
