Histone degradation after DNA damage enhances repair

DNA damage can occur anywhere in the genome, but most DNA is wrapped around nucleosomes making it inaccessible to the repair machinery. Researchers from the Gasser group now show that DNA damage induces histone depletion, which increases the accessibility and flexibility of the DNA fiber and enhances the rate of homology search during repair by homologous recombination.
