parp1的酶活性(将(多聚adp)核糖(PAR)链添加到蛋白质上)通过导致更容易接近的染色质和PAR依赖性DNA修复蛋白的募集来启动DNA修复。新的研究表明,这些parp1催化的功能是由细胞中的辅助因子HPF1重定向的。
The enzymatic activity of PARP1—which adds chains of (poly-ADP)-ribose (PAR) to proteins—initiates DNA repair by leading to more-accessible chromatin and recruitment of PAR-dependent DNA-repair proteins. New work shows that these PARP1-catalysed functions are redirected by the auxiliary factor HPF1 in cells.
