Kinase inhibitors are important cancer therapeutics. Polypharmacology is commonly observed, requiring thorough target deconvolution to understand drug mechanism of action. Using chemical proteomics, we analyzed the spectrum 243 clinically evaluated kinase drugs. The data revealed previously unknown targets for established drugs, offered a perspective on "druggable" kinome, highlighted (non)kinase off-targets, and suggested potential therapeutic applications. Integration phosphoproteomic...

Isobaric stable isotope labeling using, for example, tandem mass tags (TMTs) is increasingly being applied large-scale proteomic studies. Experiments focusing on proteoform analysis in drug time course or perturbation studies large patient cohorts greatly benefit from the reproducible quantification of single peptides across samples. However, such often require hundreds micrograms that cost reagents represents a major contribution to overall an experiment. Here, we describe and evaluate...

Abstract Nano-flow liquid chromatography tandem mass spectrometry (nano-flow LC–MS/MS) is the mainstay in proteome research because of its excellent sensitivity but often comes at expense robustness. Here we show that micro-flow LC–MS/MS using a 1 × 150 mm column shows reproducibility chromatographic retention time (<0.3% coefficient variation, CV) and protein quantification (<7.5% data from >2000 samples human cell lines, tissues body fluids. Deep analysis identifies >9000...

Although most cancer drugs modulate the activities of cellular pathways by changing posttranslational modifications (PTMs), little is known regarding extent and time- dose-response characteristics drug-regulated PTMs. In this work, we introduce a proteomic assay called decryptM that quantifies drug-PTM modulation for thousands PTMs in cells to shed light on target engagement drug mechanism action. Examples range from detecting DNA damage chemotherapeutics, identifying drug-specific PTM...

The coordination of protein synthesis and degradation regulating abundance is a fundamental process in cellular homeostasis. Today, mass spectrometry-based technologies allow determination endogenous turnover on proteome-wide scale. However, standard dynamic SILAC (Stable Isotope Labeling Cell Culture) approaches can suffer from missing data across pulse time-points limiting the accuracy such analysis. This issue particular relevance when studying stability at level proteoforms because often...

Abstract Proteome-wide measurements of protein turnover have largely ignored the impact post-translational modifications (PTMs). To address this gap, we employ stable isotope labeling and mass spectrometry to measure >120,000 peptidoforms including >33,000 phosphorylated, acetylated, ubiquitinated peptides for >9,000 native proteins. This site-resolved (SPOT) profiling discloses global site-specific differences in associated with presence or absence PTMs. While causal relationships...

Identifying the molecular mechanisms that promote optimal immune responses to coronavirus disease 2019 (COVID-19) vaccination is critical for future rational vaccine design. Here, we longitudinally profile innate and adaptive in 102 adults after first, second, third doses of mRNA or adenovirus-vectored COVID-19 vaccines. Using a multi-omics approach, identify key differences induced by ChAdOx1-S BNT162b2 correlate with antigen-specific antibody T cell reactogenicity. Unexpectedly, observe...

Integrated analysis of genomes, transcriptomes, proteomes and drug responses cancer cell lines (CCLs) is an emerging approach to uncover molecular mechanisms action. We extend this paradigm measuring proteome activity landscapes by acquiring integrating quantitative data for 10,000 proteins 55,000 phosphorylation sites (p-sites) from 125 CCLs. These are used contextualize p-sites predict sensitivity. For example, we find that Progesterone Receptor (PGR) associated with sensitivity drugs...

The complex architecture of transmembrane proteins requires quality control (QC) folding, membrane positioning, and trafficking as prerequisites for cellular homeostasis intercellular communication. However, it has remained unclear whether protein-specific QC hubs exist. Here we identify cereblon (CRBN), the target immunomodulatory drugs (IMiDs), a co-chaperone that specifically determines chaperone activity HSP90 toward by means counteracting AHA1. This function is abrogated IMiDs, which...

Manipulating molecules that impact T cell receptor (TCR) or cytokine signaling, such as the protein tyrosine phosphatase non-receptor type 2 (PTPN2), has significant potential for advancing cell-based immunotherapies. Nonetheless, it remains unclear how PTPN2 impacts activation, survival, and memory formation of cells. We find deficiency renders cells in vivo vitro less dependent on survival-promoting cytokines, interleukin (IL)-2 IL-15. Remarkably, briefly ex vivo-activated PTPN2-deficient...

Protein kinases are important mediators of intracellular signaling and reversibly activated by phosphorylation. Immobilized kinase inhibitors can be used to enrich these often low-abundance proteins, identify targets inhibitors, or probe their selectivity. It has been suggested that the binding affinity beads reflects a kinase's activation status, concept is under considerable debate. To assess merits idea, we performed series experiments including quantitative phosphoproteomics purification...

Lysine deacetylase inhibitors (KDACis) are approved drugs for cutaneous T cell lymphoma (CTCL), peripheral (PTCL), and multiple myeloma, but many aspects of their cellular mechanism action (MoA) substantial toxicity not well understood. To shed more light on how KDACis elicit responses, we systematically measured dose-dependent changes in acetylation, phosphorylation, protein expression response to 21 clinical pre-clinical KDACis. The resulting 862,000 dose-response curves revealed,...

Abstract Deubiquitylases (DUBs) are therapeutically amenable components of the ubiquitin machinery that stabilize substrate proteins. Their inhibition can destabilize oncoproteins may otherwise be undruggable. Here, we screened for DUB vulnerabilities in multiple myeloma, an incurable malignancy with dependency on proteasome system and identified OTUD6B as oncogene drives G1/S‐transition. LIN28B, a suppressor microRNA biogenesis, is specified bona fide cell cycle‐specific OTUD6B....

Abstract The electrogenic sodium bicarbonate cotransporter 1, NBCe1 (SLC4A4), is the major transporter expressed in astrocytes. It highly sensitive for and main regulator of intracellular, extracellular, synaptic pH, thereby modulating neuronal excitability. However, despite these essential functions, molecular mechanisms underlying NBCe1‐mediated astrocytic response to extracellular pH changes are mostly unknown. Using primary mouse cortical astrocyte cultures, we investigated effect...

Abstract We longitudinally profiled immune responses in 102 adults who received BNT162b2 (Pfizer-BioNTech) or ChAdOx1-S (Oxford-AstraZeneca) as their primary vaccinations. Bloods were collected pre-vaccination, 1-7 days after the 1 st , 2 nd and 3 rd doses (BNT162b2 mRNA-1273) to assess innate early adaptive responses, ∼28 immunogenicity. Using a multi-omics approach including RNAseq, cytokine multiplex assay, proteomics, lipidomics, flow cytometry we identified key differences induced by...
