[Research progress on DNA polymerase beta and genetic instability].


DNA polymerase beta (pol beta), a predominant enzyme involved in DNA base excision repair (BER), plays an important role in repair of DNA damage and maintaining stability and integrality of genome. Pol beta lacks 3' to 5' proofreading activity, which contributes to its low fidelity in DNA synthesis. There are different results about action rule of pol beta in genetic instability and mechanism of pol beta in tumorigenesis. The structure and function of pol beta, the relationship between pol beta and genome instability, and abnormal expression and mutation of pol beta in tumor were reviewed.

Using Polbase tables:


Tables may be sorted by clicking on any of the column titles. A second click reverses the sort order. <Ctrl> + click on the column titles to sort by more than one column (e.g. family then name).


It is also possible to filter the table by typing into the search box above the table. This will instantly hide lines from the table that do not contain your search text.
