ICC/IF image of ab26343 stained T47D cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab26343 at 1μg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43μM.

Supplementary information

DNA polymerase beta often abbreviated as pol β serves as a repair enzyme that plays a role in the base excision repair (BER) pathway. This protein's mechanical function involves filling small gaps in the DNA created during repair processes by adding nucleotides. Its molecular weight is approximately 39 kDa. DNA polymerase beta is expressed extensively in the brain liver and testis indicating its importance in DNA repair in various cells. Other names for this protein include DNA pol beta and pol β. It synthesizes DNA using deoxyribonucleotide triphosphates as substrates and requires magnesium ions for activity.
Biological function summary

DNA polymerase beta helps to maintain genome integrity by repairing DNA lesions caused by oxidation alkylation or deamination. This protein often collaborates with other components of the DNA repair pathways but it does not directly form a larger protein complex focusing instead on its important function in BER. When DNA damage like single-strand breaks occur pol β carries out important gap-filling synthesis steps preparing the strand for subsequent ligation.

Pathways

DNA polymerase beta functions critically in base excision repair and acts alongside other important proteins like XRCC1. The BER pathway operates to correct DNA damage from endogenous sources preventing harmful mutations. This pathway is essential for maintaining cellular stability and protecting cells from apoptosis or malignant transformation that might occur if DNA damage propagates.

Mutations or dysfunctional activity within DNA polymerase beta have links to cancer and neurodegenerative diseases. For example errors in pol β's repair functions can lead to the persistence of DNA damage which can contribute to tumorigenesis. Furthermore its relationship with beta-actin has implications in cellular structural integrity and cancer metastasis. Dysfunctions within the BER pathway indicate potential contributions to neurodegenerative disorders where an accumulation of DNA damage is a common feature.

Target data

Repair polymerase that plays a key role in base-excision repair (PubMed : 10556592, PubMed : 9207062, PubMed : 9572863). During this process, the damaged base is excised by specific DNA glycosylases, the DNA backbone is nicked at the abasic site by an apurinic/apyrimidic (AP) endonuclease, and POLB removes 5'-deoxyribose-phosphate from the preincised AP site acting as a 5'-deoxyribose-phosphate lyase (5'-dRP lyase); through its DNA polymerase activity, it adds one nucleotide to the 3' end of the arising single-nucleotide gap (PubMed : 10556592, PubMed : 17526740, PubMed : 9556598, PubMed : 9572863, PubMed : 9614142). Conducts 'gap-filling' DNA synthesis in a stepwise distributive fashion rather than in a processive fashion as for other DNA polymerases. It is also able to cleave sugar-phosphate bonds 3' to an intact AP site, acting as an AP lyase (PubMed : 9614142).
