线粒体DNA(MtDNA)双链断裂(DSB)修复是维持mtDNA完整性所必需的,但对参与mtDNA DSB修复的蛋白质知之甚少。在这里,我们使用酿酒酵母作为真核模型来鉴定参与mtDNA DSB修复的蛋白质。我们发现Mhr1,一个已知在体外具有同源DNA配对活性的蛋白质,在体内与mtDNA DSB结合,表明它参与了mtDNA DSB的修复。我们的数据还表明,Yku80是一种先前参与mtDNA DSB修复的蛋白质,它不与Mhr1竞争结合mtDNA DSB。事实上,在酵母线粒体提取液中不能检测到C末端标记的Yku80。因此,我们得出结论,在酵母中,Mhr1而不是Yku80是一个潜在的线粒体DNA DSB修复因子。
Mitochondrial DNA (mtDNA) double-strand break (DSB) repair is essential for maintaining mtDNA integrity, but little is known about the proteins involved in mtDNA DSB repair. Here, we utilize Saccharomyces cerevisiae as a eukaryotic model to identify proteins involved in mtDNA DSB repair. We show that Mhr1, a protein known to possess homologous DNA pairing activity in vitro, binds to mtDNA DSBs in vivo, indicating its involvement in mtDNA DSB repair. Our data also indicate that Yku80, a protein previously implicated in mtDNA DSB repair, does not compete with Mhr1 for binding to mtDNA DSBs. In fact, C-terminally tagged Yku80 could not be detected in yeast mitochondrial extracts. Therefore, we conclude that Mhr1, but not Yku80, is a potential mtDNA DSB repair factor in yeast.
