Poly-(ADP-ribosylation) is a post-translational modification with broad roles in cell signaling. A recently reported crystal structure reveals how the accessory factor HPF1 extends the catalytic active site of PARP1 and PARP2 to promote the specific ADP-ribosylation of serine residues, a prerequisite for dynamic chromatin changes induced by DNA damage.

将PARP标记为丝氨酸作用。

聚(ADP-核糖基化)是翻译后修饰,在细胞信号转导中具有广泛的作用。最近报道的晶体结构揭示了辅助因子HPF1如何扩展PARP1和PARP2的催化活性位点,以促进丝氨酸残基的特异性ADP-核糖基化,这是由DNA损伤引起的动态染色质变化的前提。
