靶标
-
功能
Repair polymerase. Conducts "gap-filling" DNA synthesis in a stepwise distributive fashion rather than in a processive fashion as for other DNA polymerases. Has a 5'-deoxyribose-5-phosphate lyase (dRP lyase) activity. -
序列相似性
Belongs to the DNA polymerase type-X family. -
结构域
Residues 239-252 form a flexible loop which appears to affect the polymerase fidelity. -
翻译后修饰
Methylation by PRMT6 stimulates the polymerase activity by enhancing DNA binding and processivity. -

Image courtesy of Human Protein Atlas ab26343 staining DNA polymerase beta in Human gall bladder, showing a strong nuclear staining pattern in the columnar epithelial cells in contrast with the cells in the lamina propria. Paraffin embedded human gall bladder tissue was incubated with ab26343 (1/150 dilution) for 30 mins at room temperature. Antigen retrieval was performed by heat induction in citrate buffer pH 6.
ab26343 was tested in a tissue microarray (TMA) containing a wide range of normal and cancer tissues as well as a cell microarray consisting of a range of commonly used, well characterised human cell lines. Further results for this antibody can be found at www.proteinatlas.org

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.
