响应于遗传毒性应激,PIDD蛋白促进肿瘤抑制蛋白p53下游的细胞凋亡。在本期Cell中,Janssens等人(2005)证明,在对这种应激的反应中,PIDD形成一种核复合物,增强NEMO的SUMO化。这种修饰对于抗凋亡转录因子NF-κB的活化是重要的。
In response to genotoxic stress, the PIDD protein promotes apoptosis downstream of the tumor-suppressor protein p53. In this issue ofCell, Janssens et al. (2005) demonstrate that, in response to such stress, PIDD forms a nuclear complex that enhances sumoylation of NEMO. This modification is important for the activation of the antiapoptotic transcription factor NF-κB.
