Recombinant Human POLB Protein，His

POLB, or Polymerase Beta, is a DNA polymerase that plays a crucial role in the base excision repair (BER) pathway, which is vital for the maintenance of genomic stability by repairing damaged DNA. It is known for its ability to incorporate nucleotides opposite damaged bases and fill in single-strand breaks. The study of POLB has garnered significant attention due to its implications in cancer biology, as dysregulation or mutations in POLB may contribute to tumorigenesis and resistance to certain chemotherapeutic agents. Additionally, POLB has been implicated in neurological disorders, emphasizing its importance beyond cancer. Researchers have been focusing on understanding the structural and functional aspects of POLB through various biochemical and biophysical techniques, including X-ray crystallography and single-molecule analysis, to unravel its mechanism of action and regulation. The recombinant expression of POLB allows for the production of large quantities of the enzyme, facilitating in-depth studies of its catalytic properties and interactions with other repair factors. This research is essential for developing targeted therapies that could enhance the efficacy of existing treatments by modulating POLB activity, potentially leading to novel strategies for combating cancer and other diseases associated with DNA damage. Overall, POLB represents a critical target for understanding DNA repair mechanisms and developing therapeutic innovations in the fight against diseases linked to genomic instability.
