MetabolomicsMetabolic Footprinting of a Clear Cell Renal Cell Carcinoma in vitro Model for Human Kidney Cancer Detection
A protocol for harvesting and extracting extracellular metabolites from an in vitro model of human renal cell lines was developed to profile the exometabolome by means of a discovery-based metabolomics approach using ultraperformance liquid chromatography coupled to quadrupole-time-of-flight mass sp...

ProteomicsNanoparticles and photochemistry for Native-like transmembrane protein footprinting
Mass spectrometry based footprinting can probe higher order structure of proteins. We bond photocatalytic nanoparticles to a lipid bilayer that, upon laser irradiation, produce high local concentrations of radicals that penetrate the lipid layer made permeable by a simultaneous laser-initiated PB re...

ProteomicsCarbene Footprinting Accurately Maps Binding Sites in Protein-Ligand and Protein-Protein Interactions
Specific interactions between proteins and their binding partners are fundamental to life processes. Differential protein footprinting using a new and efficient, photo-activated aryltrifluromethylcarbene probe together with mass spectrometry has been employed to identify protein-ligand and protein-p...

MetabolomicsMass Spectrometry-Based Metabolic Fingerprinting Contributes to Unveil the Role of RSUME in Renal Cell Carcinoma Cell Metabolism
Clear cell renal cell carcinoma (ccRCC) is a heterogeneous disease with 50-80% patients exhibiting mutations in the von Hippel-Lindau (VHL) gene. RSUME (RWD domain (termed after three major RWD-containing proteins: RING finger-containing proteins, WD-repeat-containing proteins, and yeast DEAD (DEXD)...

ProteomicsCarbene footprinting reveals binding interfaces of a multimeric membrane spanning protein
Mapping the interaction sites between membrane spanning proteins is a key challenge in structural biology. Here we develop and apply carbene footprinting technology to identify the interfacial sites of a trimeric membrane protein. We show how the footprinting probe is effectively incorporated into d...

ProteomicsMapping the Interaction between Eukaryotic Initiation Factor 4A (eIF4A) and the Inhibitor Hippuristanol Using Carbene Footprinting and Mass Spectrometry
Protein-ligand interactions are central to protein activity and cell functionality. Improved knowledge of these relationships greatly benefits our understanding of key biological processes and aids in rational drug design towards the treatment of clinically relevant diseases. Carbene footprinting is...

ProteomicsDimethylthiourea as a Quencher in Hydroxyl Radical Protein Footprinting Experiments
Hydroxyl radical protein footprinting (HRPF) is a mass spectrometry (MS)-based method for studying protein structures, interactions, conformations, and folding. We evaluated dimethylthiourea (DMTU) as a replacement for catalase in quenching HRPF reactions. We observed that the DMTU is highly effecti...

Using carbene footprinting, we map the MOMP-QPLEX interaction and show by complementary in silico docking that QPLEX enters the porin channel through interactions at the extracellular face, translocates down the channel through a dipole transverse electric field towards the opposite end and is relea...
