DNA polymerases (or DNA-directed DNA polymerases) are enzymes that catalyse the addition of deoxyribonucleotides to replicating DNA strands and they play crucial roles in the processes that repair different types of DNA damage.

DNA polymerase beta Show summary »

Target Id 3231
Nomenclature DNA polymerase beta
Genes POLB (Hs), Polb (Mm), Polb (Rn)
Ensembl ID ENSG00000070501 (Hs), ENSMUSG00000031536 (Mm), ENSRNOG00000019150 (Rn)
UniProtKB AC P06746 (Hs), Q8K409 (Mm), P06766 (Rn)

oleanolic acid pIC50 5.6 [2]
Comment DNA polymerase beta plays a key role in the DNA base-excision repair (BER) process. Its inhibition is being explored for potential to exploit synthetic lethality (SL) as a targeted anticancer strategy, in malignancies with defects in their DNA repair pathways [5].
