Monitoring Proteome Stress in Live Cells Using HaloTag-Based Fluorogenic Sensor.

Fluorescent folding sensor is a powerful tool to detect proteome stresses, including heat, osmotic, oxidative, and drug induced stresses. Monitoring proteome stress using these sensors allows us to dissect the mechanism of cellular stress and find therapeutics that ameliorate stress related diseases. Here we present a HaloTag-based fluorogenic proteome stress sensor (AgHalo) to robustly detect and quantify proteome stresses in live cells. We describe how proteome stresses are monitored in both bacterial and...

Comparison of the Rat and Human Dorsal Root Ganglion Proteome.

Dorsal root ganglion (DRG) are a key tissue in the nervous system that have a role in neurological disease, particularly pain. Despite the importance of this tissue, the proteome of DRG is poorly understood, and it is unknown whether the proteome varies between organisms or different DRG along the spine. Therefore, we profiled the proteome of human and rat DRG. We identified 5,245 proteins in human DRG and 4959 proteins in rat DRG. Across species the proteome is largely conserved with some notable differenc...

An update of the functional mitochondrial human proteome network.

Due to the pivotal role of mitochondrial alterations in several diseases, the Human Proteome Organization (HUPO) has promoted in recent years an initiative to characterize the mitochondrial human proteome, the mitochondrial human proteome project (mt-HPP). Here, we generated an updated version of the functional mitochondrial human proteome network, made by nodes (mitochondrial proteins) and edges (gold binary interactions), using data retrieved from neXtProt, the reference database for HPP metrics. The prin...

Analysis of PNGase F-resistant N-glycopeptides using SugarQb for Proteome Discoverer 2.1 reveals cryptic substrate specificities.

SugarQb ( is a freely available collection of computational tools for the automated identification of intact glycopeptides from high-resolution HCD MS/MS data-sets in the Proteome Discoverer environment. We report the migration of SugarQb to the latest and free version of Proteome Discoverer 2.1, and apply it to the analysis of PNGase F-resistant N-glycopeptides from mouse embryonic stem cells. The analysis of intact glycopeptides highlights unexpected technical limitations to PN...

iTRAQ-based quantitative analysis of age-specific variations in salivary proteome of caries-susceptible individuals.

Human saliva is a protein-rich, easily accessible source of potential biomarkers for the diagnosis of oral and systemic diseases. However, little is known about the changes in salivary proteome associated with aging of patients with dental caries. Here, we applied isobaric tags for relative and absolute quantitation (iTRAQ) in combination with multiple reaction monitoring mass spectrometry (MRM-MS) to characterize the salivary proteome profiles of subjects of different ages, presenting with and without cari...

Salivary proteome patterns of individuals exposed to High Altitude.

Identification of molecular signatures having key roles in hypobaric hypoxia by analysing the salivary proteome. Saliva holds a promising future in the search for new clinical biomarkers that are easily accessible, less complex, accurate, and cost effective as well as being non-invasive.

Extending single molecule imaging to proteome analysis by quantitation of fluorescent labeling homogeneity in complex protein samples.

Fluorescence-based electrophoresis has been widely used for proteome analysis, in which every protein species in cells are labeled with a fluorescent dye, separated by electric migration and are quantified using fluorescence detection. The ultimate limit of sensitivity for this approach could be reached by single-molecule fluorescence imaging and counting individual proteins, requiring exhaustive fluorescent labeling of proteins across molecular populations and species. However, it remains unclear how homog...

Affinity Purification of Methyllysine Proteome by Site-Specific Covalent Conjugation.

To separate the targeted proteome from the whole protein mixture is a basic but critical step of affinity-purification coupled to mass spectrometry (AP-MS). The bait protein is usually immobilized on the surface of a solid support to enable affinity-based purification of the targeted proteome. Here, we developed a site-specific covalent immobilization of the bait protein through an affinity-guided covalent coupling (AGCC) of a single cysteine residue of an SH2 domain (utilized as an affinity tag of the prot...

Rapid remodeling of the host epithelial cell proteome by the listeriolysin O pore-forming toxin.

Bacterial pathogens use various strategies to interfere with host cell functions. Among these strategies, bacteria modulate host gene transcription, thereby modifying the set of proteins synthetized by the infected cell. Bacteria can also target pre-existing host proteins and modulate their post-translational modifications or trigger their degradation. Analysis of protein levels variations in host cells during infection allows to integrate both transcriptional and post-transcriptional regulations induced by...

Orthologous proteins of experimental de- and remyelination are differentially regulated in the CSF proteome of multiple sclerosis subtypes.

Here, we applied a multi-omics approach (i) to examine molecular pathways related to de- and remyelination in multiple sclerosis (MS) lesions; and (ii) to translate these findings to the CSF proteome in order to identify molecules that are differentially expressed among MS subtypes.

Flexible and fast mapping of peptides to a proteome with ProteoMapper.

Bottom-up proteomics relies on the proteolytic or chemical cleavage of proteins into peptides, the identification of those peptides via mass spectrometry, and the mapping of the identified peptides back to the reference proteome to infer which possible proteins are identified. Reliable mapping of peptides to proteins still poses substantial challenges when considering similar proteins, protein families, splice isoforms, sequence variation, and possible residue mass modifications, combined with an imperfect ...

Inventory of proteoforms as a current challenge of proteomics: Some technical aspects.

The main intricacy in the human proteome is that it is tremendously complex and composed from diverse and heterogeneous gene products. These products are called protein species or proteoforms and are the smallest units of the proteome. In pursuit of the comprehensive profiling of the human proteome, significant advances in the technology of so called "Top-Down" mass spectrometry based proteomics, have been made. However, the scale of performance of this approach is still far behind the "Bottom-Up", peptide-...

Identification of viral domains integrated into Arabidopsis proteome.

Horizontal gene transfer (HGT) contributes to the genome evolution of living organisms. In particular, several recent studies provide convincing data on the integration of viral sequences into diverse organisms. Here, we identified 101 viral domains integrated into the model plant Arabidopsis proteome. Functional analysis based on gene ontology (GO) terms indicates that viral domains in the Arabidopsis proteome were involved in various stress responses with binding functions. Protein interaction networks su...

Alteration of the colostrum whey proteome in mothers with gestational hypothyroidism.

Gestational hypothyroidism (G-HypoT) is one of the most common thyroid diseases in pregnant women. Human milk, which closely links the mother with infant, is an important factor to the infant health. Here, we analyzed the colostrum whey proteome of women with or without G-HypoT.

Thermal proteome profiling in bacteria: probing protein state .

Increasing antibiotic resistance urges for new technologies for studying microbes and antimicrobial mechanism of action. We adapted thermal proteome profiling (TPP) to probe the thermostability of proteins had a more thermostable proteome than human cells, with protein thermostability depending on subcellular location-forming a high-to-low gradient from the cell surface to the cytoplasm. While subunits of protein complexes residing in one compartment melted similarly, protein complexes spanning compartmen...
