Description: ML323 is a reversible and effective USP1-UAF1 inhibitor in a Ub-Rho assay (IC50: 76 nM) and in orthogonal gel-based assays using K63-linked diubiquitin (di-Ub) (IC50: 174 nM 820 nM)and monoubiquitinated PCNA (Ub-PCNA) (IC50: 820 nM) as substrates, respectively. Target: DUB. Smiles:...

The USP1 deubiquitinating enzyme, which regulates the DNA translesion synthesis (TLS) and Fanconi anemia (FA) DNA damage response pathways by deubiquitinating the central players of these pathways, is activated by the WD40-repeat containing UAF1 protein through formation of a stable USP1-UAF1 protein complex.
