Mutations caused by DNA damage are a main driver of cancer. We discovered that recognition of newly synthesised histone H4 directs breast cancer type 1 susceptibility protein (BRCA1) to post-replicative chromatin. The switch from mutagenic to error-free DNA double strand break repair by homologous recombination is therefore controlled by chromatin.
由DNA损伤引起的突变是癌症的主要驱动因素。我们发现,对新合成的组蛋白H4的识别可将乳腺癌1型易感蛋白(BRCA1)导向复制后的染色质。因此,通过同源重组从诱变型DNA双链断裂修复向无差错修复的转变受染色质控制。
