MetabolomicsCell Membrane Remodeling Mediates Polymyxin B Resistance in Klebsiella pneumoniae: An Integrated Proteomics and Metabolomics Study
Polymyxin B (PB) is introduced into the clinic as the last-line therapy against carbapenem-resistant Klebsiella pneumoniae (CRKP). Unfortunately, increased resistance to PB in Klebsiella pneumoniae (K. pneumoniae) has threatened global health. Resistance of K. pneumoniae ...

ProteomicsSITE-SPECIFIC ACTIVITY-BASED PROTEIN PROFILING USING PHOSPHONATE HANDLES
Most drug molecules target proteins. Identification of the exact drug binding sites on these proteins is essential to understand and predict how drugs affect protein structure and function. To address this challenge, we developed a strategy that uses IMAC-enrichable phosphonate affinity tags, for ef...

ProteomicsValidation and application of a novel KLK6 activity based probe (IMP2352)
Pancreatic cancer has the lowest survival rate of all common cancers due to late diagnosis and limited treatment options. Serine hydrolases are known to mediate cancer progression and metastasis through initiation of signaling cascades and cleavage of extracellular matrix proteins, and the kallikrei...

ProteomicsDual-Probe Activity-Based Protein Profiling Reveals Site-Specific Binding Dynamics of EGFR-Directed Drugs
Comparative, dose-dependent analysis of interactions between small molecule drugs and their targets, as well as off-targets, in complex proteomes is crucial for selecting optimal drug candidates. The affinity of small molecules for targeted proteins is largely dictated by interactions between amino ...

ProteomicsABPP-HT - high-throughput activity-based profiling of deubiquitylating enzyme inhibitors in a cellular context
The potency and selectivity of a small molecule inhibitor are key parameters to assess during the early stages of drug discovery. In particular, it is very informative for characterizing compounds in a relevant cellular context in order to reveal potential off-target effects and drug efficacy. Activ...

ProteomicsDiscovery of highly Potent and Selective Activity-Based Probes for the Deubiquitylating Enzyme USP30
Ubiquitin-specific protease 30 (USP30) is a deubiquitylating enzyme (DUB) localized in the mitochondrial membrane, which is related to PINK1/Parkin-mediated mitophagy, pexophagy, BAX/BAK-dependent apoptosis, and IKKβ-USP30-ACLY-regulated lipogenesis/tumorigenesis. Mission therapeutics pointed their ...

Ubiquitin carboxy-terminal hydrolase L1 (UCHL1) is a deubiquitinating enzyme (DUB) that is very highly expressed in human brain. UCHL1 has been proposed as a potential therapeutic target in neurodegeneration, cancer, and liver and lung fibrosis, however bona fide molecular functions of UCHL1 are yet...
