摘要：

Efficient DNA damage sensing and repair is crucial to preserve genomic integrity and failure to detect or repair DNA breaks can cause mutations, contributing to the formation of tumors. One key protein required for mediating DNA repair is the tumor suppressor 53BP1. Recent studies now demonstrate the crucial role of K48-linked ubiquitination and protein degradation for 53BP1 recruitment at sites of DNA damage.
