Biological roles of obscurin and its close homolog Obsl1 (obscurin-like 1) have been enigmatic. While obscurin is highly expressed in striated muscles, Obsl1 is found ubiquitously. Accordingly, obscurin mutations have been linked to myopathies, whereas mutations in Obsl1 result in 3M-growth syndrome. To further study unique and redundant functions of these closely related proteins, we generated and characterized Obsl1 knockouts. Global Obsl1 knockouts are embryonically lethal. In contrast, skele ...[more]

Comparative single-cell transcriptional and proteomic atlas of clinical-grade injectable mesenchymal source tissues

Project description:Bone marrow aspirate concentrate (BMAC) and adipose-derived stromal vascular fraction (ADSVF) are the most marketed stem cell therapies to treat a variety of conditions in the general population and elite athletes. Both tissues have been used interchangeably clinically even though their detailed composition, heterogeneity, and mechanisms of action have neither been rigorously inventoried nor compared. This lack of information has prevented investigations into ideal dosages and has facilitated anecdata and misinformation. Here, we analyzed single-cell transcriptomes, proteomes, and flow cytometry profiles from paired clinical-grade BMAC and ADSVF. This comparative transcriptional atlas challenges the prevalent notion that there is one therapeutic cell type present in both tissues. We also provide data of surface markers that may enable isolation and investigation of cell (sub)populations. Furthermore, the proteome atlas highlights intertissue and interpatient heterogeneity of injected proteins with potentially regenerative or immunomodulatory capacities.

Identification of the bacteriophage nucleus protein interaction network

Project description:Here, we use proximity labeling and localization mapping to systematically identify proteins associated with the major nuclear shell protein chimallin (ChmA) and other distinctive structures assembled by these phages. We identify six uncharacterized nuclear shell-associated proteins, one of which directly interacts with self-assembled ChmA. The structure and protein-protein interaction network of this protein, which we term ChmB, suggests that it forms pores in the ChmA lattice that serve as docking sites for pro-capsid genome packaging, and may also participate in mRNA and/or protein transport.

Cyclin B3 is a dominant fast-acting cyclin that drives rapid early embryonic mitoses

Project description:Mitosis in early embryos often proceeds at a rapid pace, but how this pace is achieved is not understood. Here we show that cyclin B3 is the dominant driver of rapid embryonic mitoses in the C. elegans embryo. Cyclins B1 and B2 support slow mitosis (NEBD to Anaphase ~600s) but the presence of cyclin B3 dominantly drives the ~3-fold faster mitosis observed in wildtype. Multiple mitotic events are slowed down in Cyclin B1&B2-driven mitosis and cyclin B3-associated Cdk1 H1 kinase activity is ~25-fold more active than cyclin B1-associated Cdk1. Addition of cyclin B1 to fast cyclin B3-only mitosis introduces an ~60s delay between completion of chromosome alignment and anaphase onset; this delay, which is important for segregation fidelity, is dependent on inhibitory phosphorylation of the anaphase activator Cdc20. Thus, cyclin B3 dominance, coupled to a cyclin B1-dependent delay that acts via Cdc20 phosphorylation, sets the rapid pace and ensures mitotic fidelity in the early C. elegans embryo.

Digestive Enzyme Activity and Protein Degradation in Plasma of Heart Failure Patients

Project description:Heart failure is associated with degradation of cell functions and extracellular matrix proteins, but the trigger mechanisms are uncertain. Our recent evidence in acute multiorgan failure suggests that active digestive enzymes leak out of the small intestine into the systemic circulation and cause cell dysfunctions and organ failure. Accordingly, we investigated in morning fasting plasma of heart failure (HF) patients the presence of pancreatic trypsin, a major enzyme responsible for digestion. Western analysis shows that trypsin in plasma is significantly elevated in HF compared to matched controls and their concentrations correlate with inflammatory biomarkers. The plasma trypsin levels in HF are accompanied by elevated pancreatic lipase concentrations. The trypsin has a significantly elevated activity as determined by substrate cleavage. Mass spectrometry shows that the number of proteins in the HF group is similar to controls while the number of peptides was increased about 20% in the HF patients. The peptides are derived from extracellular and intracellular protein sources and exhibit cleavage sites by trypsin as well as other degrading proteases. These results provide first evidence that active digestive enzymes leak into the systemic circulation and may participate in myocardial cell dysfunctions and tissue destruction in HF.

Monitoring α-synuclein ubiquitination dynamics reveals key endosomal effectors mediating its trafficking and degradation

Project description:While defective α-synuclein homeostasis is central to the pathogenesis of Parkinson’s, fundamental questions about its intracellular trafficking remain unresolved. We have developed a bimolecular fluorescence complementation assay in living cells to monitor de novo ubiquitination of α-synuclein. We identified lysine residues 45, 58 and 60 as critical ubiquitination sites for the degradation of α-synuclein. This is mediated by NBR1 binding to ubiquitinated α-synuclein and entry into endosomes in a process that involves ESCRT I-III complexes for subsequent lysosomal degradation. Autophagy or the autophagic chaperone Hsc70 are dispensable for this pathway. Antibodies against diglycine-modified α-synuclein peptides confirmed that endogenous α-synuclein is similarly ubiquitinated in brain and targeted to the lysosome in rat primary and human iPSC-derived neurons. Ubiquitinated α-synuclein was detected in Lewy bodies and cellular models of aggregation suggesting that it may be entrapped with endo/lysosomes in inclusion bodies. Collectively, our data elucidate the intracellular trafficking of de novo ubiquitinated α-synuclein and provide the tools for investigating the rapidly turned-over fraction of this disease-causing protein.

Evolution of Modularity, Interactome and Functions of GIV/Girdin (CCDC88A) from Invertebrates to Vertebrates

Project description:PDZ domains are one of the most abundant protein domains in eukaryotes and frequently found on junction-localized scaffold proteins. Various signaling molecules bind to PDZ proteins via PDZ-binding motifs (PBM) and finetune cellular signaling. Here we describe the presence of a PBM on GIV/Girdin (CCDC88A) that is conserved throughout evolution, from invertebrates to vertebrates, and is generated as a long isoform-variant in humans, which we named GIV-L. Unlike GIV, which lacks PBM and is cytosolic, GIV-L localizes to the cell junctions, and has a unique PDZ-interactome, which impacts GIV-L’s ability to bind and activate trimeric G-protein, Gi through its guanine-nucleotide exchange modulator (GEM) module; the GEM module is found exclusively in vertebrates. Thus, the two functional modules in GIV evolved sequentially: the ability to bind PDZ proteins via the PBM evolved earlier in invertebrates, whereas G-protein binding and activation may have evolved later only among vertebrates. Phenotypic studies in Caco-2 cells revealed that GIV and GIV-L may have antagonistic effects on cell growth, proliferation (cell cycle), and survival. Immunohistochemical analyses in human colon tissues showed that GIV expression increases with a concomitant decrease in GIV-L during cancer initiation. Taken together, these findings reveal how GIV/CCDC88A in humans displays evolutionary flexibility in modularity, which allows the resultant isoforms to play opposing roles either as a tumor suppressor (GIV-L) or as an oncogene (GIV).

Polypyrimidine Tract Binding Proteins PTBP1 and PTBP2 Interact with Distinct Proteins Under Splicing Conditions

Project description:RNA binding proteins play an important role in regulating alternative pre-mRNA splicing and in turn cellular gene expression. Polypyrimidine tract binding proteins, PTBP1 and PTBP2, are paralogous RNA binding proteins that play a critical role in the process of neuronal differentiation and maturation; changes in the concentration of PTBP proteins during neuronal development direct splicing changes in many transcripts that code for proteins critical for neuronal differentiation. How the two related proteins regulate different sets of neuronal exons is unclear. The distinct splicing activities of PTBP1 and PTBP2 can be recapitulated in an in vitro splicing system with the differentially regulated N1 exon of the c-src pre-mRNA. Here, we conducted experiments under these in vitro splicing conditions to identify PTBP1 and PTBP2 interacting partner proteins.

A phage nucleus-associated RNA-binding protein is required for jumbo phage infection

Project description:Large-genome bacteriophages (jumbo phages) of the Chimalliviriadae family assemble a nucleus-like compartment bounded by a protein shell that protects the replicating phage genome from host-encoded restriction enzymes and CRISPR/Cas nucleases. While the nuclear shell provides broad protection against host nucleases, it necessitates transport of mRNA out of the nucleus-like compartment for translation by host ribosomes, and transport of specific proteins into the nucleus-like compartment to support DNA replication and mRNA transcription. Here we identify a conserved phage nuclear shell-associated protein that we term Chimallin C (ChmC), which adopts a nucleic acid-binding fold, binds RNA with high affinity in vitro, and binds phage mRNAs in infected cells. ChmC also forms phase-separated condensates with RNA in vitro. Targeted knockdown of ChmC using mRNA-targeting dCas13d halts infections at an early stage. Taken together, our data suggest that the conserved ChmC protein acts as a chaperone for phage mRNAs, potentially stabilizing these mRNAs and driving their translocation through the nuclear shell to promote translation and infection progression.

Role of SurA, BamB, BamC and HlpA for shaping the outer membrane protein composition of Pseudomonas aeruginosa

Project description:Pseudomonas aeruginosa (Pa) is one of the main causative agents of nosocomial infections and the spread of multidrug-resistant strains is rising. The outer membrane composition of Pa restricts antibiotic entry and determines virulence. For efficient outer membrane protein biogenesis, the BAM complex and chaperones like Skp and SurA are crucial. Deletion mutants of bamB, bamC and the skp homolog hlpA as well as a conditional mutant of surA were investigated. The most profound effects were associated with a lack of SurA, characterized by increased membrane permeability, enhanced sensitivity to antibiotic treatment and attenuation of virulence in a Galleria mellonella infection model. Strikingly, the conditional deletion of surA in a multidrug-resistant bloodstream isolate re-sensitized the strain to antibiotic treatment. Mass spectrometry revealed striking alterations in the outer membrane composition. Thus, SurA of Pa is important for the insertion of many porins, type V secretion systems, TonB-dependent receptors, proteins involved in LPS transport and BAM complex components. Therefore, SurA of Pa serves as a promising target for developing a drug that shows antiinfective activity and sensitizes multidrug-resistant strains to antibiotics.

Single-cell identification of L1HS-Ta retrotransposons in preimplantation embryos by ATLAS-seq

Project description:We used ATLAS-seq to comprehensively map the genomic location of LINE-1 elements belonging to the youngest and potentially polymorphic subfamily (L1HS-Ta). This was performed in single-cells of 2 preimplantation embryos (E3 and E6) as well as from the remaining inner cell mass (denoted T). In brief, single cells were isolated from the inner cell mass of preimplantation embryos by laser drilling and micromanipulation. Whole-genome Multiple Displacement Amplification was performed on each isolated single cells, as well as on the remaining cells of the inner cell mass as a population (samples labelled 'T'). Then we applied ATLAS-seq to map L1HS-Ta retrotransposons. This approach relies on the random mechanical fragmentation of the genomic DNA to ensure high-coverage, ligation of adapter sequences, suppression PCR-amplification of L1HS-Ta element junctions, and Ion Torrent sequencing using single-end 400 bp read chemistry. A notable aspect of ATLAS-seq is that we can obtain both L1 downstream and upstream junctions (3'- and 5'-ATLAS-seq libraries, respectively), for full-length L1 elements.
