Deubiquitinating enzymes play an important role in a plethora of therapeutically relevant processes, and are emerging as pioneering drug targets. Herein, we present a novel probe Ubiquitin Specific Protease (USP) inhibitor, alongside an alkyne-tagged activity-based probe analogue. Activity-based proteome profiling identified 12 USPs, including USP4, USP16, and USP33, as inhibitor targets using sub-micromolar probe concentrations. This represents the first intact cell activity-based profiling of deubiquitinating enzymes...

Ubiquitin-Specific Proteases (USPs) are deubiquitinating enzymes frequently deregulated in human malignancies. Here, we show that USP54 is overexpressed in intestinal stem cells and demonstrate that its downregulation in colorectal carcinoma cells impedes tumorigenesis. We have generated mutant mice deficient for this deubiquitinase, which are viable and fertile, and protected against chemically-induced colorectal carcinoma. Furthermore, we show that USP54 is upregulated in human colon cancer and associates with poor prognosis...

To begin studies on reproduction in common bed bug, Cimex lectularius, we identified three genes coding for vitellogenin (Vg, a protein required for the reproductive success of insects) and studied their hormonal regulation. RNA interference studied showed that expression of Vg3 gene in the adult females is a prerequisite for successful completion of embryogenesis in the eggs laid by them. Juvenile hormone (JH) receptor, Methoprene-tolerant (Met), steroid receptor coactivator (SRC) and GATAa but not ecdysone receptor (EcR) or its partner, ultraspiracle (USP) are required for expression of Vg genes...

USP17 is a deubiquitinating enzyme that is upregulated in numerous cancers and therefore a drug target. We developed a robust expression, purification, and assay system for USP17 enabling its enzymatic and structural characterization. USP17 was expressed in E. coli as inclusion bodies and then solubilized, refolded, and purified using affinity and size-exclusion chromatography. Milligram quantities of pure USP17 can be produced that is catalytically more efficient (kcat/Km = 1500 (x10(3)) M(-1) sec(-1)) than other human USPs studied to date...
