DNA-protein crosslink repair.

Stingele J , Jentsch S .


???displayArticle.abstract???
DNA-protein crosslinks (DPCs) are highly toxic DNA adducts, but whether dedicated DPC-repair mechanisms exist was until recently unknown. This has changed with discoveries made in yeast and Xenopus laevis that revealed a protease-based DNA-repair pathway specific for DPCs. Importantly, mutations in the gene encoding the putative human homologue of a yeast DPC protease cause a human premature ageing and cancer predisposition syndrome. Thus, DPC repair is a previously overlooked genome-maintenance mechanism that may be essential for tumour suppression.
