A variety of internal and external agents can cause DNA damage in cells. Many factors influence how the repair route is selected, including the cell cycle phase and chromatin segment where the break occurred. In terms of initiating 5’ end DNA repair, the p53 binding protein 1(53BP1) and BRCA 1 are important protein components that influence Double-strand break repair pathway selection. The 53BP1 complex attaches to chromatin near DNA break and activities downstrea… WebTherefore, the local chromatin environment at sites of DNA damage could be shaped by PARP1 through two complementary mechanisms: first, chromatin relaxation through …
