DNA polymerase beta is sensitive to Mn2+ and Mg2 (show MCOLN1 Proteins)+ and its optimumal pH is 9.
In brief, the major differences in BER performed by early stage embryos and adults are the absence of DNA polymerase-beta, leading to predominance of replicative polymerases, in early stage embryos.
Data show that esophageal carcinoma (EC) cells expressing the DNA polymerase beta K167I variant to be sensitive to DNA damaging agents.
Pol lambda (show POLL Proteins) can incorporate rNMPs opposite normal bases or 8-oxo-G, and with a different fidelity. Further, the incorporation of rNMPs opposite 8-oxo-G delays repair by DNA glycosylases.
POLB was pinpointed as a target gene of miR (show MLXIP Proteins)- 499. Additionally, we identified that miR (show MLXIP Proteins)-499 can enhance cisplatin's function of inhibiting proliferation and of promoting apoptosis in EC9706 and KYSE30 cell lines.
Since APE1 (show APEX1 Proteins), XRCC1 (show XRCC1 Proteins) and POLB proteins operate downstream the same DNA repair pathway to eliminate DNA oxidative damage, their expression above basal levels found in our study could reveal excessive oxidative stress in high-grade bladder tumors.
findings indicate that the IKBKB and POLB SNPs confer no genetic predisposition to SLE risk in this Chinese Han population
The structure of pol beta in binary complex with template 8-oxoG in a base excision repair substrate, is reported.[Dna polymerase beta]
Fen1 (show FEN1 Proteins) significantly stimulated trinucleotide repeats expansion by Pol beta, but not by the related enzyme Pol lambda (show POLL Proteins).
Data show that tongue cancer resistance-associated protein 1 (TCRP1) contributes to cisplatin (DDP (show TIMM8A Proteins)) resistance via the increased expression of DNA polymerase beta subunit (Pol beta) in lung cancer cells.
DNA polymerase beta catalyzes lesion bypass across benzo[a]pyrene-derived DNA adduct in an error prone manner.
HSP90 (show HSP90 Proteins) regulates DNA repair by interaction between XRCC1 (show XRCC1 Proteins) and DNA polymerase beta.
pol beta plays an important role in bypassing a 5',8-cyclo-dA during DNA replication and repair.
we show here that heterozygosity for a Y265C mutation in Polbeta, a key polymerase in the BER pathway, is enough to significantly reduce both the number of expansions seen in paternal gametes and the extent of somatic expansion in some tissues
The aberrant DNA replication mediated by the PCNA (show PCNA Proteins)-DNA pol-b complex induces p53 (show TP53 Proteins)-dependent neuronal cell death
Y265C POLB mutation leads to several pathologies associated with SLE and short CDR3 regions during VDJ recombination in B cells.
Pol beta deficiency could enable ROS (show ROS1 Proteins) accumulation.
Results show that deficiency of either DNA polymerases beta or lambda or both results in a modest but significant decrease in V region somatic hypermutation (SHM (show CNTNAP1 Proteins)) with no effect on mutation specificity, suggesting no direct role in SHM (show CNTNAP1 Proteins).
Transient OGG1 (show OGG1 Proteins), APE1 (show APEX1 Proteins), PARP1 (show PARP1 Proteins) and Polbeta expression in an Alzheimer's disease mouse model.
Data indicate an association of ovarian stimulation with a downregulation of mRNAs encoding the base excision repair proteins APEX1 (show APEX1 Proteins) and POLB as well as the 5-methyl-CpG-binding domain protein MBD3 (show MBD3 Proteins) in individual morula embryos.
Overexpression of Pol beta could reduce oxidative damage and protect cells from hydroquinone genotoxicity.
Polbeta could protect cells from apoptosis induced by hydroquinone through decrease of ROS (show ROS1 Proteins) level and depolarization of mitochondria.
The protein encoded by this gene is a DNA polymerase involved in base excision and repair, also called gap-filling DNA synthesis. The encoded protein, acting as a monomer, is normally found in the cytoplasm, but it translocates to the nucleus upon DNA damage. Several transcript variants of this gene exist, but the full-length nature of only one has been described to date.
