Ubiquitin-specific protease 1 (USP1) is the founding member of the family of cysteine proteases that catalyse hydrolysis of the isopeptide bond between ubiquitin and targets. USP1 is often overexpressed in various cancers, and expression levels correlate with poor prognosis. USP1 and its partner USP1-associated Factor 1 (UAF1) are required for deubiquitinating monoubiquitin signals in DNA interstrand crosslink repair, and in Translesion synthesis, among others, and both proteins are subject to multiple regulations themselves. This review covers recent findings on the mechanisms and functions of USP1 in DNA repair, its regulation, and its potential as a target for therapeutic intervention.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
