Anti-POLB (DNA polymerase beta)

This product was affinity purified from monospecific antiserum by immunoaffinity chromatography. This antibody reacts with overexpressed and endogenous POLß protein. A BLAST analysis was used to suggest reactivity with POLß from human, bovine, and Xenopus laevis based on a 100% homology with the immunizing sequence. Cross-reactivity with POLß from other sources has not been determined. Protein function: Repair polymerase that plays a key role in base-excision repair. Has 5'-deoxyribose-5-phosphate lyase (dRP lyase) activity that removes the 5' sugar phosphate and also acts as a DNA polymerase that adds one nucleotide to the 3' end of the arising single-nucleotide gap. Conducts 'gap-filling' DNA synthesis in a stepwise distributive fashion rather than in a processive fashion as for other DNA polymerases. [The UniProt Consortium]
