The assay is designed to identify small molecules that inhibit the activity of USP1, a type of deubiquitinating enzyme that is involved in various diseases. The assay is based on a fluorescent read-out and is being used to screen the NIH Molecular Libraries Small Molecule Repository (MLSMR) to identify potential drug candidates. Inhibiting USPs provides a potentially specific therapeutic intervention that may reduce side-effects and increase efficacy. Is the molecule effective to this assay?
