Summary
DNA damage is identified and repaired through posttranslational modifications (PTMs). This review highlights the crucial roles of arginine and lysine methylation in orchestrating DNA repair processes.
Area of Science:
- Molecular Biology
- Genetics
- Biochemistry
Background:
- DNA is constantly damaged by mutagens.
- Accurate DNA repair requires precise localization of repair machinery.
- Posttranslational modifications (PTMs) are key regulators of DNA damage response.
Purpose of the Study:
- To review recent findings on the role of methylation in DNA repair.
- To emphasize the significance of arginine and lysine methylation in DNA repair pathways.
Main Methods:
- Literature review of recent research data.
- Analysis of the roles of specific PTMs in DNA repair.
Main Results:
- PTMs like phosphorylation, ubiquitination, sumoylation, acetylation, and methylation orchestrate DNA repair.
- Arginine and lysine methylation are specifically implicated in DNA repair processes.
Conclusions:
- Methylation, particularly arginine and lysine methylation, plays a critical role in DNA repair.
- Understanding these methylation events is vital for comprehending DNA damage response.

Overview of DNA Repair
In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

Epigenetic Regulation
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Mismatch Repair
Overview
Mismatch Repair
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
