Human POLB ELISA Kit for Sandwich ELISA - ABIN421299
Li, Li, Yu, Zhang, Wang, Jia: miR-3940-5p associated with genetic damage in workers exposed to hexavalent chromium. in Toxicology letters 2014
DNA polymerase beta is sensitive to Mn2+ and Mg2 (show MCOLN1 ELISA Kits)+ 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.
In the mitochondrial extracts from APTX (show APTX ELISA Kits)-/- cells, the strong pol beta lyase and FEN1 (show FEN1 ELISA Kits) activities appear able to repair the blocked BER intermediates with 5'-AMP (show APRT ELISA Kits)-dRP (show UTRN ELISA Kits) groups.Neither pol gamma (show POLG ELISA Kits) lyase nor FEN1 (show FEN1 ELISA Kits) alone is able to complement APTX (show APTX ELISA Kits) deficiency in the absence of pol beta.
human polymerase beta, accommodates 8-oxoG at the primer terminus opposite cytosine and adenine.
POLB functions in base excision repair to fill in single-nucleotide gaps and exhibits mutation E288K associated with colon cancer. Data suggest that E288K mutant POLB exhibits faster rate of closing of fingers domain combined with slower rate of nucleotide release compared to wild-type POLB; loss of fidelity appears due to defect in interaction of E288K mutant POLB with DNA, resulting in stable, closed enzyme structure.
Unencumbered polymerase beta lyase activity in nucleosome core particles during base excision repair has been reported.
pol beta and BRCA1 appeared to have a functional interaction, observed in both DT40 and human cell lines, in protecting cells against alkylating MMS-induced cytotoxicity; but pol beta had no protective effect in the absence of BRCA1. In vivo and in vitro assays for a base excision repair role of BRCA1 were negative.
pol beta contains a specific NLS (show ALDH1A2 ELISA Kits) sequence in the N-terminal lyase domain that promotes transport of the protein independent of its interaction partners. Active nuclear uptake allows development of a nuclear/cytosolic concentration gradient against a background of passive diffusion.
Data suggest that POLB activity is not essential for HIV-1 integration into human macrophages and other cells; limited cellular dNTP pools, but not POLB expression, are primary factor for HIV-1 DNA gap repair, particularly in non-dividing cells.
High DNA polymerase beta mRNA expression is associated with Graves' thyroid tissue.
Polbeta was shown to inhibit the 3'->5' exonuclease activity of APE1 (show APEX1 ELISA Kits) when both enzymes were added simultaneously and to insert the correct nucleotide into the gap arising after hydrolysis of AP site clustered with the benzo[a]pyrene adducts.
Remote mutations induce functional changes in active site residues of human 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 ELISA Kits)-DNA pol-b complex induces p53 (show TP53 ELISA Kits)-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 ELISA Kits) 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 ELISA Kits)) with no effect on mutation specificity, suggesting no direct role in SHM (show CNTNAP1 ELISA Kits).
Transient OGG1 (show OGG1 ELISA Kits), APE1 (show APEX1 ELISA Kits), PARP1 (show PARP1 ELISA Kits) 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 ELISA Kits) and POLB as well as the 5-methyl-CpG-binding domain protein MBD3 (show MBD3 ELISA Kits) in individual morula embryos.
Overexpression of Pol beta could reduce oxidative damage and protect cells from hydroquinone genotoxicity.
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.
