A possible role of repair proteins BRCA1 and DNA-PK in the processing of oxidative DNA damage


BRCA1 and DNA-PK are two significant multifunctional proteins involved primarily in the processing of double strand breaks (DSBs). BRCA1 participates actively in homologous recombination (HR) while DNA-PK in non-homologous end joining (NHEJ). In this mini review, we discuss all recent evidence for a possible involvement of these repair proteins also in the processing of oxidatively-induced DNA damage.Keyword: DNA damage, BRCA1, DNA-PKReceived: 6 June 2008, Accepted: 10 August 2008 Published online: 18 August 2008
