Both environmental and endogenous factors induce various forms of DNA damage. DNA double strand break (DSB) is the most deleterious DNA lesion. The swift initiation of a complexed network of interconnected pathways to repair the DNA lesion is essential for cell survival. In the past years, the roles of ubiquitin and ubiquitin-like proteins in DNA damage response and DNA repair has been explored. These findings help us better understand the complicated mechanism of DSB signaling pathways.
环境因素和内源性因素都会诱发各种形式的DNA损伤。DNA双链断裂(DSB)是最具危害性的DNA损伤。迅速启动一个由相互关联的通路组成的复杂网络来修复DNA损伤对于细胞存活至关重要。在过去几年里,泛素和类泛素蛋白在DNA损伤应答和DNA修复中的作用得到了探索。这些发现有助于我们更好地理解DSB信号通路的复杂机制。
