Ubiquitylation-Mediated Fine-Tuning of DNA Double-Strand Break Repair

Cancers (Basel). 2020 Jun 18;12(6):1617. doi: 10.3390/cancers12061617.

Abstract

The proper function of DNA repair is indispensable for eukaryotic cells since accumulation of DNA damages leads to genome instability and is a major cause of oncogenesis. Ubiquitylation and deubiquitylation play a pivotal role in the precise regulation of DNA repair pathways by coordinating the recruitment and removal of repair proteins at the damaged site. Here, we summarize the most important post-translational modifications (PTMs) involved in DNA double-strand break repair. Although we highlight the most relevant PTMs, we focus principally on ubiquitylation-related processes since these are the most robust regulatory pathways among those of DNA repair.

Keywords: DNA repair; DSB; PTM; deubiquitylation; ubiquitylation.
