P166 links membrane and intramitochondrial modules of the trypanosomal tripartite attachment complex

ABSTRACT: p166 is a central component of a protein complex that is essential for mitochondrial genome segregation in Trypanosoma brucei. The last 34 aa (the C-tail) of p166 are absolutely essential for its function of p166. The prupose of this experiment is to find even putative binding partners interacting with p166. For this purpose, two CoIP experiments with a truncated soluble version of p166 were performed. One uses p166 with an intact C-tail whereas the C-tail is removed in a second experiment. Differences between the two CoIPs indicate potential interactors of the C-tail.

The protist parasite Trypanosoma brucei has a single mitochondrion with a single unit genome termed kinetoplast DNA (kDNA). Faithfull segregation of replicated kDNA is ensured by a complicated structure termed tripartite attachment complex (TAC). The TAC physically links the basal body of the flagellum with the kDNA spanning the two mitochondrial membranes. Here, we characterized p166 as the only known TAC subunit that is anchored in the inner membrane. Its C-terminal transmembrane domain separa ...[more]

Complementary peptides (cPEPs) modulate protein translation

Project description:MicroRNAs (miRNAs) are small regulatory RNAs that control plant and animal development by regulating post-transcriptional gene expression. Primary transcripts of miRNAs contain small ORFs that can be translated into small peptides (miPEPs). MiPEPs specifically enhance the expression of their cognate miRNA in a positive feedback loop. Here, by addressing the molecular bases of miPEP specificity, we identified an unanticipated mechanism modulating coding gene expression. We found that the miORF itself constitutes a prerequisite for the miPEP to specifically control the expression of its miRNA. We extended this property to any coding gene through the design of artificial peptides. We called these peptides « complementary peptides » (cPEPs) as their external application modulates the translation of their corresponding protein. We discovered here a yet undescribed mechanism of post-transcriptional regulation, opening new promising avenues in fundamental research and applied biology. Quantitative proteomics using LC-MS/MS after co-immunoprecipitation with a HA-tagged cPEP or scrambled peptide was performed to identify interactors of the cPEP or scrambled peptide in co-eluates of plants.

Triggered offset fragmentation allows massively multiplexed target profiling on quadrupole-orbitrap mass spectrometers

Project description:Parallel reaction monitoring (PRM) on quadrupole-orbitrap mass spectrometers has a limited multiplexing capacity which depends heavily on the reproducibility of peptide retention times. To overcome these limitations, we aimed to establish a data acquisition mode that allows retention-time-independent massive multiplexing on quadrupole-orbitrap mass spectrometers. The presented method is based on data-dependent acquisition and is called pseudo-PRM. In principle, high-intensity stable isotope-labeled peptides are used to trigger the repeated fragmentation of the corresponding light peptides. In this way, pseudo-PRM data can be analyzed like normal PRM data with Skyline. We tested pseudo-PRM for the target detection from yeast, human cells, and serum, and assessed the quantification accuracy/precision and sensitivity. Moreover, we analyzed multiplexing of more than 1,000 targets in a single pseudo-PRM run. Finally, we applied pseudo-PRM to quantify vaccinia virus proteins during infection, verifying that pseudo-PRM presents an alternative method for multiplexed target profiling on quadrupole-orbitrap mass spectrometers.

Revealing the Structural Plasticity of SARS-CoV-2 nsp7 and nsp8 Using Structural Proteomics (XL-MS)

Project description:SARS-CoV-2 nsp7 and nsp8 are important cofactors of the RTC, as they interact and regulate the activity of RNA-dependent RNA polymerase and other nspsHere we used solution-based structural proteomic techniques, hydrogen-deuterium exchange mass spectrometry (HDX-MS) and crosslinking mass spectrometry (XL-MS), illuminate the dynamics of SARS-CoV-2 full-length nsp7, nsp8, and nsp7:nsp8 proteins and protein complex.

Biochemical and structural insights into SARS-CoV-2 polyprotein processing by Mpro (XL-MS)

Project description:SARS-CoV-2, a human coronavirus, is the causative agent of the COVID-19 pandemic, entailing enormous disruption worldwide. Its ~30 kb RNA genome is translated into two large polyproteins subsequently cleaved by viral papain-like protease and main protease (Mpro/nsp5). Polyprotein processing is essential yet incompletely understood. We studied Mpro-mediated processing of the nsp7-10/11 polyprotein, whose mature products are cofactors of the viral replicase, identifying the order of cleavages: 1) nsp9-10, 2) nsp8-9/nsp10-11, and 3) nsp7-8. Integrative modeling based on mass spectrometry (including hydrogen-deuterium exchange and cross-linking) and X-ray scattering yielded three-dimensional models of the nsp7-10/11 polyprotein, and the data suggest that the nsp7-10/11 structure in complex with Mpro strongly resembles the unbound polyprotein. Our array of techniques supports the notion that interplay between polyprotein conformation and junction accessibility determine the preference and order of cleavages. Finally, we leveraged assays of limited proteolysis by Mpro of nsp7-11 using a series of inhibitors/binders to characterize Mpro inhibition using a polyprotein substrate.

C4PR_LIV: The SARS-CoV-2 ORF3C protein interactome in Vero cells

Project description:The SARS-CoV-2 genome encodes a multitude of accessory proteins. Using comparative genomic approaches, an additional accessory protein, ORF3c, has been predicted to be encoded within the ORF3a sgmRNA. Expression of ORF3c during infection has been confirmed independently by ribosome profiling. Despite ORF3c also being present in the 2002-2003 SARS-CoV, its function has remained unexplored. Here we show that ORF3c localises only to mitochondria during infection, where it inhibits innate immunity by restricting IFN-β production, but not NF-κB activation or JAK-STAT signalling downstream of type I IFN stimulation. We find that ORF3c acts after stimulation with cytoplasmic RNA helicases RIG-I or MDA5 or adaptor protein MAVS, but not after TRIF, TBK1 or phospho-IRF3 stimulation. ORF3c co-immunoprecipitates with the antiviral proteins MAVS and PGAM5 and induces MAVS cleavage by caspase-3. Unlike early lineage SARS-CoV-2 strains, delta variant strains lack intact ORF3c and do not cleave MAVS to the same extent. Together, these data provide insight into an uncharacterised mechanism of innate immune evasion by this important human pathogen. We suggest a model whereby ORF3c inhibits PGAM5-induced mitophagy and instead induces apoptosis, accompanied by caspase-3 activation. This repository contains data associated with the SARS-CoV-2 ORF3C SILAC AP-MS portions of this work.

ACBD5 phosphorylationsite analysis

Project description:Peroxisomes (POs) and the endoplasmic reticulum (ER) cooperate in cellular lipid metabolism and form membrane contacts, which are mediated by the peroxisomal membrane proteins acyl-coenzyme A-binding domain protein 4 and 5 (ACBD4/5) which bind to the resident ER protein vesicle-associated membrane protein-associated protein B (VAPB). ACBD4/5 bind to the major sperm protein (MSP) domain of VAPB via their FFAT-like [two phenylalanines (FF) in an acidic tract] motif. The molecular mechanisms which regulate membrane contact site formation and dynamics are not well explored, in particular in mammalian cells. Here, we reveal that peroxisome-ER associations via the ACBD5-VAPB tether are regulated by phosphorylation.

Immunoprecipitation-Mass Spectrometry (IP-MS) identifies components of a Mce4A-containing complex

Project description:How lipids travel between membranes of diderm bacteria is a challenging mechanistic question because lipids, which are hydrophobic molecules, must traverse a hydrophilic periplasm. This question is even more complex for mycobacteria, which have a unique cell envelope that is highly impermeable to molecules. A growing body of knowledge identifies Mce transporters as lipids importers for mycobacteria. Here, using protein stability experiments and immunoprecipitation-mass spectrometry to identify protein interactions among components of the mycobacterial Mce4 transporter we provide evidence for Mce transporters existing as multiprotein complexes.

Cooperative polarization of MCAM/CD146 and ERM family proteins in melanoma

Project description:The WRAMP structure is a protein network associated with tail-end actomyosin contractility, membrane retraction, and directional persistence during cell migration. A marker of WRAMP structures is melanoma cell adhesion molecule (MCAM) which dynamically polarizes to the cell rear. However, factors that mediate MCAM polarization are still unknown. In this study, BioID using MCAM as bait identifies the ERM family proteins, moesin, ezrin, and radixin, as WRAMP structure components. We also present a novel image analysis pipeline, Protein Polarity by Percentile (“3P”), which classifies protein polarization using machine learning and facilitates quantitative analysis. Using 3P, we find that depletion of moesin, and to a lesser extent ezrin, decreases the proportion of cells with polarized MCAM. Furthermore, although co-polarized MCAM and ERM proteins show high spatial overlap, 3P identifies subpopulations with ERM proteins closer to the cell periphery. Live-cell imaging confirms that MCAM and ERM protein polarization is tightly coordinated, but ERM proteins enrich at the cell edge first. Finally, deletion of a juxtamembrane segment in MCAM previously shown to promote ERM protein interactions impedes MCAM polarization. Our findings highlight the requirement for ERM proteins in recruitment of MCAM to WRAMP structures and an advanced computational tool to characterize protein polarization.
