The roles of different histone modifications have been explored extensively in a number of nuclear processes, particularly in transcriptional regulation. Only recently has the role of histone modification in signaling or facilitating DNA repair begun to be elucidated. DNA broken along both strands in the same region, a double-strand break, is damaged in the most severe way possible and can be the most difficult type of damage to repair accurately. To successfully repair the double-strand break, the cell must gain access to the damaged ends of the DNA and recruit repair factors, and in the case of homologous recombination repair, the cell must also find, colocalize, and gain access to a suitable homologous sequence. In the repair of a double-strand break, the cell must also choose between homologous and non-homologous pathways of repair. Here, we will briefly review the mechanisms of double-strand-break repair, and discuss the known roles of histone modifications in signaling and repairing double-strand breaks.Key words: H23A, double strand break repair, histone modification.
