Quantitative Proteomics Illuminates A Functional Interaction Between Mouse Homolog Of Diaphanous 2 (mDia2) And The Proteasome

ABSTRACT: Formin mDia2 is a cytoskeleton-regulatory protein that switches reversibly between a closed, auto-inhibited and an open, active conformation. Although the open conformation of mDia2 induces actin assembly thereby controlling many cellular processes, mDia2 possesses also actin-independent and conformation-insensitive scaffolding roles related to microtubules and p53, respectively. Thus, we hypothesise that mDia2 may have other unappreciated functions and regulatory modes. Here we identify and validate proteasome and Ubiquitin as genuine mDia2-interacting partners using quantitative proteomics and a multi-disciplinary approach, respectively.

Proteomic analysis uncover a new function and mode of action for mDia2

Project description:mDia2 is an auto-inhibited Formin influencing actin dynamics upon conversion to the active conformation. mDia2 regulates actin-based protrusions and cell invasion, cell differentiation, vesicle trafficking and cytokinesis. However, whether mDia2 has additional functions and how its action is functionally specified remain unknown. Here we draw the interactome of auto-inhibited and constitutively active mDia2 to address these issues. We embed mDia2 in protein networks accounting for its attributed functions and unexpectedly link it to the Ubiquitin Proteasome System. Taking FBXO3 as a test case, we show that mDia2 binds FBXO3 and p53, and regulates p53 transcriptional activity in an actin-nucleation-independent and conformation-insensitive manner. Increased mDia2 and FBXO3 levels elevate p53 activity and expression thereby sensitizing cells to p53-dependent apoptosis, whereas their decrease produces opposite effects. Thus, we discover a new role of mDia2 in p53 regulation suggesting that the closed conformation is biologically active and an FBXO3-based mechanism to functionally specify mDia2’s activity.

Ubiquitin-based pathway acts inside chloroplasts to regulate photosynthesis

Project description:Photosynthesis is the energetic basis for most life on Earth, and in plants it operates inside double-membrane-bound organelles called chloroplasts. The photosynthetic apparatus comprises numerous proteins encoded by the nuclear and organellar genomes. Maintenance of this apparatus requires the action of internal chloroplast proteases, but a role for the nucleocytosolic ubiquitin-proteasome system (UPS) was not expected owing to the barrier presented by the double-membrane envelope. Here, we show that photosynthesis proteins (including those encoded internally by chloroplast genes) are ubiquitinated, and processed via the CHLORAD pathway: they are degraded by the 26S proteasome following CDC48-dependent retrotranslocation to the cytosol. This demonstrates that the reach of the UPS extends to the interior of endosymbiotically-derived chloroplasts, where it acts to regulate one of the most fundamental processes of life.

Positional proteomics reveals differences in N-terminal proteoform stability.

Project description:To understand the impact of alternative translation initiation on a proteome, we performed the first large-scale study of protein turnover rates in which we distinguish between N-terminal proteoforms pointing to translation initiation events. Using pulsed SILAC combined with N-terminal COFRADIC we monitored the stability of 1,941human N-terminal proteoforms, including 147 proteoform pairs with heterogeneous N-termini originating from the same gene that result from alternative translation initiation and incomplete processing of the initiator methionine. N-terminally truncated proteoforms were on average less abundant than canonical proteoforms, many had different stabilities and exhibited both faster and slower turnover rates compared to their canonical counterparts. These differences in stability did not depend on the length of truncation but on individual protein characteristics. In silico simulation of N-terminal proteoforms in macromolecular complexes revealed possible consequences for complex integrity such as replacement of unstable canonical subunits. The extent of intrinsic disorder in N-terminal protein structures correlated with turnover times, indicating that a change in the structural flexibility of protein N-termini in truncated proteoforms might impact proteoform stability. Interestingly, removal of the initiator methionine by methionine aminopeptidases reduced the stability of processed proteoforms while susceptibility for N-terminal acetylation, another common co-translational modification, did not seem to impact on turnover rates. Taken together, our findings reveal differences in protein stability between N-terminal proteoforms and point to a role for alternative translation initiation and co-translational initiator methionine removal in the overall regulation of proteome homeostasis.

Genome wide mapping of long range contacts unveils DNA Double Strand Breaks clustering at damaged active genes.

Project description:Translocations, that occur when two DNA Double Strand breaks (DSBs) are abnormally rejoined, represent highly deleterious genome rearrangements favoring cancer apparition and progression. However, the mechanisms that drive their formation are yet poorly deciphered. One prerequisite for translocation is the juxtaposition of two distant DSBs, an event that would be favored if DSB cluster, i.e. are brought together in close spatial proximity within the nucleus. Whether DSB cluster in higher eukaryotes has been subjected to a strong controversy over the past decade, due to conflicting results obtained using microscopy based methods1-9. Here we used for the first time a high throughput chromosome conformation capture assay (Capture Hi-C10) to investigate DSB clustering. We unambiguously found that DSBs do cluster in human nuclei but only when induced in transcriptionally active genes. Clustering of damaged genes mainly occur during the G1 cell cycle phase and coincide with delayed repair. Moreover DSB clustering depends on the MRN complex, as well as the Formin 2 (FMN2) nuclear actin organizer and the LINC (LInker of Nuclear and Cytoplasmic skeleton) complex, suggesting that active mechanisms promote DSB clustering. This work reveals that when damaged, active genes exhibit a very peculiar behavior compared to the rest of the genome, being mostly left unrepaired and clustered in G1 while being repaired by homologous recombination in post-replicative cells.

RNA-seq, ChIP-seq and ATAC-seq analysis of MKL1 blocked cells during reprogramming

Project description:Actins and regulators of actin dynamics generate contractile forces providing major mechanical and structural support for the cell. Whether and how they actively participate in cell fate control is not clear. Here, we report the actin responsive transcription factor complex MKL1/SRF, the major transcriptional regulator of large numbers of actin cytoskeletal genes, as an important regulator of genomic accessibility and cell fate outcome. Somatic cells with weaker MKL1/SRF activity progress toward pluripotency efficiently while sustained MKL1/SRF activity at a level seen in typical fibroblasts is sufficient to stall cells on their trajectory toward pluripotency. This altered cell fate outcome is associated with an overactive actin cytoskeleton, which connects to chromatin via the LINC complex, preventing its conversion into a relaxed, open conformation that allows sufficient accessibility to pluripotency-inducing transcription factors. Interfering with actin polymerization at appropriate times promotes pluripotency induction. Thus, we reveal a previously unappreciated aspect of cell fate control exerted by the actin based cytoskeletal system.

Comprehensive identification of full-length mRNA isoforms reveals massive diversity of neural cell-surface molecules and illuminates their function in development and disease

Project description:Genes encoding cell-surface proteins are crucial for nervous system development and are implicated in neurological disorders. These genes produce alternative mRNA isoforms which remain poorly characterized, impeding our understanding of how disease-associated mutations cause pathology. Here we introduce a new strategy to reveal complete full-length isoform portfolios encoded by individual genes. Using our strategy to catalog diversity of neural cell surface molecules, we identified thousands of unannotated isoforms expressed in retina and brain. Mass spectrometry revealed that many newly-discovered proteins are expressed on the cell surface in vivo. Remarkably, we discover that the major isoform of the retinal degeneration gene CRB1 was previously overlooked. This isoform is the only one expressed by photoreceptors, the affected cells in CRB1 disease. By generating mouse mutants, we reveal a function for this isoform at the cell-cell junctions of the retinal outer limiting membrane, and we provide a causal link between loss of this Crb1 isoform and photoreceptor death. Therefore, our isoform identification strategy accelerates discovery of new gene functions relevant to disease.

The Caveolin3 complex stabilizes functional surface expression of the Lactate-Proton Shuttle McT1 but not the sodium channel Nav1.5 in cardiomyocytes

Project description:Caveolin3 variants were associated with action potential prolongation. As Caveolin1 was recently identified in cardiomyocytes, we hypothesize that conserved isoform-specific protein interactions underlie human loss-of-function variants. To analyze the Caveolin1 and Caveolin3 interactome, we developed unbiased live-cell proteomic and isoform-specific mass spectrometry techniques. We demonstrate the functional relevance and pathogenic mechanism of a novel Caveolin3 interactor in gene-edited human iPSC-cardiomyocyte models.

A complex containing lysine-acetylated actin inhibits the formin INF2

Project description:INF2 is a member of the formin family of actin assembly factors. Dominant mis-sense mutations in INF2 link to two diseases: focal segmental glomerulosclerosis (FSGS), a kidney disease; and Charcot-Marie-Tooth disease (CMTD), a neuropathy. All disease mutations map to the autoinhibitory Diaphanous Inhibitory Domain (DID). Curiously, purified INF2 is not autoinhibited, suggesting the existence of additional cellular inhibitors. We purified an INF2 inhibitor from mouse brain, and identified it as a complex between lysine-acetylated actin (KAc-actin) and cyclase-associated protein (CAP). Inhibition of INF2 by CAP/KAc-actin requires INF2 DID. Treatment of CAP/KAc-actin with histone deacetylase 6 (HDAC6) releases INF2 inhibition, while HDAC6 inhibitors block cellular INF2 activation. INF2 disease mutants are poorly inhibited by CAP/KAc-actin, suggesting that FSGS and CMTD result from reduced CAP/KAc-actin binding. This is the first demonstrated role for lysine-acetylated actin: regulation of an actin assembly factor by a novel mechanism, which we call facilitated auto-inhibition.

Covalent binding of enzymes in the ubiquitylation cascade as a response to oxidative stress

Project description:In contrast to the general ubiquitin activation and transfer cascade, we show that Uba1 binds to ubiquitin conjugating enzymes (Ubc) even in the absence of ubiquitin under mild oxidizing conditions. We show that this binding is ATP-dependent and leads to a disulfide-linkage between the catalytic cysteine residues as demonstrated with gel shift assays and visualized in a high-resolution structure of a covalent Uba1Ubc13 complex. The structure provides additional insights into the Uba1-Ubc binding mode and reveals unexpected structural changes in the N-terminus of Uba1, leading to a more open ATP-binding pocket. Immunoprecipitation experiments with yeast cells in combination with mass spectrometry revealed that several Uba~Ubc complexes are generated in vivo under oxidative stress conditions.
