- DNA breaks especially double-strand breaks (DSBs) are extremely serious damages that can cause loss of genetic material, gene recombination, and lead to cancer or cell death.
- Eukaryotic cells have evolved a variety of mechanisms to deal with the serious threats caused by DNA double-strand breaks. This is the DNA damage response mechanism (DDR), which mainly includes DNA damage detection, signal transduction, and damage repair.
- DDR DNA damage response mechanism
- DNA double-strand break repair mainly includes homologous end joining (HR) repair and non-homologous end joining (NHEJ) repair. In higher eukaryotes, NHEJ repair, which is preferentially used during the early G1/S phase, is the main mechanism.
- DDR initial damage factors such as MRN will detect and recognize the damage site, recruit phosphoinositide kinase family members (ATM, ATR, DNA-PK), phosphorylate H2AX to promote the formation of ⁇ H2AX, guide downstream signal transduction and recruit related proteins to complete the receptor. Repair of damaged DNA.

- NHEJ non-homologous DNA double-strand breaks End join
- the Ku70/Ku80 heterodimer specifically connects to the double-stranded damage through a pre-formed channel, recognizes double-strand breaks and binds to the broken ends separately, and then follows the DNA in an ATP-dependent manner. The strands slid a certain distance to both ends to form a KU-DNA complex and recruit DNA-PKcs to bind to the double-strand break.
