Parallel comparison of mutant proteomes with altered carbon metabolism reveals Hik8 regulates PII phosphorylation and the basal level glycogen accumulation in a cyanobacterium

ABSTRACT: To understand the specificity and the cross-talk of such regulations, we simultaneously and quantitatively compared the proteomes of the gene knockout mutants for the regulators. A number of proteins showing differential expression in one or more mutants were identified, including four proteins that are unanimously upregulated or downregulated in all the five mutants. These represent the important nodes of the intricate and elegant regulatory network for carbon metabolism.

Carbon metabolism is central to photosynthetic organisms and involves the coordinated operation and regulation of numerous proteins. In cyanobacteria, proteins involved in carbon metabolism are regulated by multiple regulators including the RNA polymerase sigma factor SigE, the histidine kinases Hik8, Hik31 and its plasmid-borne paralog Slr6041, and the response regulator Rre37. To understand the specificity and the cross-talk of such regulations, we simultaneously and quantitatively compared th ...[more]

The ER stress sensor IRE1 interacts with STIM1 to promote store-operated calcium entry, T cell activation, and muscular differentiation

Project description:A quantitative phosphoproteomic study was performed on mouse embryonic fibroblasts (MEF) knocked-out of IRE1 protein and re rexpressin it culturen in 25mM glucose media. The chosen experimental strategy was to perform phosphopeptide enrichment associated with multiplex protein identification and quantification by LC-MSMS on a high-resolution mass spectrometer using tandem mass tag (TMT9; Thermo Fisher Scientific) technology and High- Select Fe-NTA Phosphopeptide Enrichment Kit (Thermo Fisher Scientific).

Synthetic peptide library

Project description:Synthetic peptides are commonly used in biomedical science for many applications in basic and translational research. Here, we assembled a large dataset of synthetic peptides whose identity was validated using mass spectrometry. We analyzed the mass spectra and used them for method validation as well as the creation of ground truth datasets and cognate databases.

A family of unconventional deubiquitinases with modular chain specificity determinants

Project description:Interactors of human ZUFSP in HEK-293T cells. Flp-in T-REx 293 cells with stable 3xFLAG-ZUFSP integration were assayed for ZUFSP interactors under three different conditions: i) Cells expressing wild-type ZUFSP, ii) Cells expressing catalytically inactive ZUFSP, iii) Cells expressing wild-type ZUFSP with additional treatment by an unspecific nuclease (Benzonase) during purification.

• YjgM is a novel crotonyltransferase critical for polymyxin resistance of Escherichia coli

Project description:Lysine crotonylation has attracted widespread attention in recent years. However, little is known about bacterial crotonylation, particularly crotonyltransferase and decrotonylase, and how it affects antibiotic resistance. Our study demonstrated the ubiquitous presence of crotonylation in E.coli and its connection to bacterial resistance to polymyxin. We first identified the crotonyltransferase YjgM and its regulatory pathways in E. coli with a focus on crotonylation. Further studies suggested that YjgM upregulates the crotonylation of the substrate protein PmrA, which is crucial for controlling E. coli's resistance to polymycin, thereby boosting PmrA's affinity for binding to the promoter of eptA, which in turn promotes EptA expression and confers polymyxin resistance in E. coli. Additionally, we discovered that PmrA's crucial crotonylation site and functional site is Lys 164. These significant discoveries highlight the role of crotonylation in bacterial drug resistance and offer a fresh perspective for creating antibacterial medicines.

GLH/VASA helicases promote germ granule formation to ensure the fidelity of piRNA-mediated transcriptome surveillance

Project description:The ability to distinguish non-self from self is the key characteristic for any defense system. piRNAs function as guardians of the genome by silencing non-self nucleic acids and transposable elements in animals. Many piRNA factors are enriched in perinuclear germ granules, but whether their localization is required for piRNA biogenesis or function is not known. Here we show that GLH/VASA helicase mutants exhibit defects in forming perinuclear condensates containing PIWI and other small RNA cofactors. These mutant animals produce largely normal levels of piRNA but are defective in triggering piRNA silencing. Strikingly, while many piRNA targets are activated in GLH mutants, we observed that hundreds of endogenous genes are aberrantly silenced by piRNAs. This defect in self versus non-self recognition was also observed in other mutants where perinuclear P granules are disrupted. Together, our results argue that perinuclear germ granules function critically to promote the fidelity of piRNA-based transcriptome surveillance in C. elegans and preserve self versus non-self distinction.

Exercise-induced molecular mechanisms for glycogen supercompensation in human skeletal muscle

Project description:A single bout of exercise followed by intake of carbohydrates leads to glycogen supercompensation in the prior exercised muscle. The molecular mechanisms underlying this well-known phenomenon remain elusive. Here we report that a single bout of exercise induces marked activation of glycogen synthase (GS) and AMP-activated protein kinase (AMPK) for several days beyond normalized muscle glycogen content in man. Acute muscle specific deletion of AMPK activity in mouse muscle abrogated the ability for glycogen supercompensation, providing genetic evidence that AMPK serves as essential driver for glycogen supercompensation. Muscle proteomic analyses revealed elevated glucose uptake capacity in the prior exercised muscle while key proteins in fat oxidation and glycolysis largely remained unchanged. The temporal order of these sustained cellular alterations induced by a single bout of exercise provide a mechanism to offset the otherwise tight feedback inhibition of glycogen synthesis and glucose uptake by glycogen, ultimately leading to muscle glycogen supercompensation.

AS precipitation and protein A affinity chromatography for abundant plasma protein depletion

Project description:Plasma is a highly valuable resource for biomarker research since it is easy obtainable and contains a high amount of information on patient health status. Although advancements in the field of proteomics enabled analysis of the plasma proteome, identification of low abundant proteins remains challenging due to high complexity and large dynamic range. In order to reduce the dynamic range of protein concentrations, a tandem depletion technique consisting of ammonium sulfate precipitation and Protein A affinity chromatography was developed. Using this method, 50 % of albumin, together with other high abundant proteins such as alpha-1-antitrypin, was depleted from the plasma sample at 20 % to 40 % ammonium sulfate saturation levels. In combination with immunoglobulin removal using a Protein A column, this technique delivered up to 40 new low- to medium abundance protein identifications when performing a shotgun mass spectrometry analysis. Compared to non-depleted plasma, 270 additional protein spots were observed during 2D-PAGE analysis. These results illustrate that this tandem depletion method is equivalent to commercial kits which are based on immune-affinity chromatography. Moreover, this method using protein A immunoglobulin depletion was shown to be highly reproducible and a minimal amount of non-target proteins was depleted. The combination of ammonium sulfate precipitation and Protein A affinity chromatography offers a low cost, efficient, straightforward and reproducible alternative to commercial kits, with proteins remaining in native conformation, allowing protein activity and protein interaction studies.

Identification and relative quantification of hFSH glycoforms in women sera by PRM MS based approach.

Project description:This study presents an alternative preliminary strategy to identify and quantify serum hFSH glycoforms based on immunopurification assay and mass spectrometry (MS) using parallel reaction monitoring (PRM) analysis. In this study, we provide MS-PRM data acquisition method for hFSH glycopeptides identification with high specificity and their quantification by extracting the chromatographic traces of selected fragments of glycopeptides. Once set up in all its features, the proposed method could be transferred to the clinic to improve the fertility treatments and follow-ups in men and women.
