Ubiquitin signalling in DNA replication and repair

Nat Rev Mol Cell Biol. 2010 Jul;11(7):479-89. doi: 10.1038/nrm2921. Epub 2010 Jun 16.


Post-translational modification by ubiquitin is best known for its role in targeting its substrates for regulated degradation. However, non-proteolytic functions of the ubiquitin system, often involving either monoubiquitylation or polyubiquitylation through Lys63-linked chains, have emerged in various cell signalling pathways. These two forms of the ubiquitin signal contribute to three different pathways related to the maintenance of genome integrity that are responsible for the processing of DNA double-strand breaks, the repair of interstrand cross links and the bypass of lesions during DNA replication.
