Post-translational modifications of lysine in DNA-damage repair.
DNA damage in cells is often the result of constant genotoxic insult. Nevertheless, efficient DNA repair pathways are able to maintain genomic integrity. Over the past decade it has been revealed that it is not only kinase signalling pathways which play a central role in this process, but also the different post-translational modifications at lysine residues of histone (chromatin) and non-histone proteins. These lysine modifications include acetylation, methylation, ubiquitination and SUMOylation. Genomic instability is often the major cause of different diseases, especially cancer, where lysine modifications are altered and thereby have an impact on the various DNA repair mechanisms. This chapter will discuss the recent advances in our understanding of the role of different lysine modifications in DNA repair and its physiological consequences.
