Substrate identification of ADAMTS16

ABSTRACT: Secreted and cell-surface proteases are major mediators of extracellular matrix remodelling, but their mechanisms and regulatory impact are poorly understood. We developed a mass spectrometry approach using cell free ECM produced by mouse Balb/c 3T3 cells in vitro to identify fibronectin as a novel substrate of the secreted metalloprotease ADAMTS16. ADAMTS16 cleaves fibronectin between its (I)5 and (I)6 modules, releasing the N-terminal 30kDa heparin-binding domain essential for fibronectin assembly.

Secreted and cell-surface proteases are major mediators of extracellular matrix (ECM) turnover, but their mechanisms and regulatory impact are poorly understood. We developed a mass spectrometry approach using a cell-free ECM produced in vitro to identify fibronectin (FN) as a novel substrate of the secreted metalloprotease ADAMTS16. ADAMTS16 cleaves FN between its (I)5 and (I)6 modules, releasing the N-terminal 30 kDa heparin-binding domain essential for FN self-ass ...[more]

Cell-intrinsic regulation of interneuron migration controls cortical neurogenesis

Project description:Interneurons navigate along multiple tangential paths to settle into appropriate cortical layer. They undergo saltatory migration, which is paced by intermittent nuclear jumps whose regulation relies on interplay between extracellular cues and genetic-encoded information. However, it remains unclear how cycles of pause and movement are coordinated at the molecular level. Post-translational modification of proteins contributes to cell migration regulation. The present study uncovers that carboxypeptidase 1, which promotes deglutamylation, is a pivotal regulator of pausing of cortical interneurons. Moreover, we show that pausing during migration controls the flow of interneurons invading the cortex by generating heterogeinity in movement at the population level. Interfering with the regulation of pausing not only affects the size of the cortical interneuron cohort but also secondarily impairs the generation of age-matched upper layer projection neurons.

Caspase-3 cleaves extracellular vesicle proteins during auditory brainstem development

Project description:Sound localization requires extremely precise development of auditory brainstem circuits, the molecular mechanisms of which are largely unknown. We previously demonstrated a novel requirement for non-apoptotic activity of the protease caspase-3 in chick auditory brainstem development. Here, we used mass spectrometry to identify proteolytic substrates of caspase-3 during chick auditory brainstem development. Functional annotation analysis revealed that our caspase-3 substrates were enriched more than two-fold for proteins associated with extracellular vesicles (EVs), membrane-bound nanoparticles that function in intercellular communication. The proteome of EVs isolated from the auditory brainstem contained caspase-3 and was highly enriched for the caspase-3 substrates identified here. Additionally, we identified two caspase-3 substrates with known functions in axon guidance, namely Neural Cell Adhesion Molecule (NCAM) and Neuronal-glial Cell Adhesion Molecule (Ng-CAM), that were found in auditory brainstem EVs and expressed in the auditory pathway alongside cleaved caspase-3. Taken together, these data suggest a novel developmental mechanism whereby caspase-3 influences auditory brainstem circuit formation through the proteolytic cleavage of EV proteins.

ALOX12-expressing macrophages produce MCTRs to promote local efferocytosis and tissue repair

Project description:Poor wound healing due to dysregulated tissue repair responses can exacerbate and prolong disease. Successful tissue repair is critically dependent on the timely clearance of apoptotic cells by macrophages in a process termed efferocytosis. Mechanisms and factors that link these two fundamental processes are therefore of great interest. Herein, we observed that a subset of 12-lipoxygenase (ALOX12)-expressing macrophages upregulate the production of host protective autacoids termed maresin conjugates in tissue regeneration (MCTR) during efferocytosis. MCTRs in turn play autocrine and paracrine functions in enhancing the ability of both ALOX12-positive and surrounding ALOX12-negative macrophages to uptake apoptotic cells. These effects of ALOX12-positive macrophages and MCTRs in regulating apoptotic cells clearance was also observed at sites of high apoptotic cell burden in mouse and flatworm models, as the formation of these mediators was upregulated and abrogation of related ALOX activity in mice reduced the ability of macrophages to clear apoptotic cells. Furthermore, add-back of MCTRs rapidly enhanced the efferocytosis capability of macrophages in mice and planarian flatworms. Mechanistic studies in macrophages revealed that MCTRs modulated Rac1 signalling and glycolytic metabolism, two pathways crucial for effective efferocytosis, and enhanced efferocytosis-induced WNT ligand production. Inhibition of Rac1 abrogated the ability of MCTRs to enhance glucose uptake and efferocytosis in vitro, while inhibiting either Rac1, glycolysis, or WNT ligand production prevented MCTR-mediated enhancement of apoptotic cell clearance and tissue regeneration. Taken together, our findings identify a central role for ALOX12-expressing macrophages in the regulation of efferocytosis and tissue repair via the local formation of MCTRs.

Spirocyclic dimer (SpiD7) activates unfolded protein response (UPR) to selectively inhibit growth and induce apoptosis of cancer cells

Project description:Protein homeostasis is maintained by a combination of tightly controlled processes which include synthesis, folding, trafficking and degradation. Transient accumulation of unfolded / misfolded proteins in the endoplasmic reticulum (ER) due to cell intrinsic and / or extrinsic signals results in the activation of unfolded protein response (UPR), an adaptation mechanism. Failure to resolve the transient accumulation results in UPR mediated programmed cell death. Loss of tumor suppressor gene or oncogene addiction in cancer cells result in a sustained higher basal UPR levels. This higher basal UPR levels in cancer cells when compared to normal cells provides a therapeutic window that can be exploited by UPR activators. Here we explored covalent modification of surface exposed cysteine (SEC) residues to simulate unfolded / misfolded proteins and induce UPR activation. A proteome-wide click-pulldown-MS study using an alkyne tagged isatin-derived spirocyclic -methylene--butyrolactone analog identified > 330 protein targets that were covalently modified. Evaluation for UPR activation with a set of analogs that can covalently modify SECs identified a spirocyclic -methylene--butyrolactone dimer (SpiD7) as a UPR activator. SpiD7 induced XBP1 splicing protected normal cells from caspase-mediated apoptosis, no such induction was observed in cancer cells, which resulted in caspase-mediated apoptosis in cancer cells. SpiD7 inhibits growth of high-grade serous carcinoma (HGSC) cell lines ~3-15 fold more potently than immortalized fallopian tube epithelial (normal) cells and reduced clonogenic growth of HGSC cell lines. Our results suggest that induction of UPR by covalent modification of SEC residues is a cancer cell vulnerability and can be exploited to discover novel therapeutics.

Proteomics exploiting modular baits with different subcellular locations reveal hydrogen peroxide-inducible clone 5 protein (HIC-5) and a glucocorticoid receptor variant as novel testin partners

Project description:The LIM domain and tumour suppressor protein Testin (Tes) is downregulated in a variety of human tumours and tumour cell lines. Depending on its conformation, Tes localises to stress fibres and focal adhesions where it forms protein complexes with other members of the actin cytoskeleton, such as zyxin and VASP, and thereby influences cellular processes like cell migration, adhesion or spreading. Tes is a modular protein and Tes variants lacking specific domains, localize to different locations in cells. To better understand the molecular basis of its function, we utilized an interaction proteomics approach combined with pathway analysis. This revealed proteins present in complexes in which Tes participates as a function of its modular structure as well as novel Tes interaction partners. We demonstrate that Tes interacts with a short isoform of the glucocorticoid receptor (GR), independently of the conventional full length GRα, a transcription factor important in regulating cellular metabolism and immune function. Tes also interacts with the focal adhesion protein and GR-coactivator Hic-5. In addition, we found that upon overexpression, Tes and Hic-5 induce opposite effects on cell spreading on a fibronectin matrix.

Microtubule associated proteins MAP7 and MAP7D1 promote 53BP1-mediated DNA double strand break repair in G1 cell cycle phase

Project description:In this project we have been looking for proteins binding to phosphorylated sites in DNA repair proteins. Previously, we and others have used peptide-pull down assays as a direct means of attributing specific binding functions to known sites phosphorylated by CK2 in DDR proteins. We have now applied the approach to identify proteins binding to four in vivo phosphorylated sites from DDR proteins RAD50 (Thr690), BRCA1 (Ser1336), MLH1 (Ser477) and XPC (Ser883, 884). These sites are conserved, reside within consensus sites for CK2, share similar sequence features, are mutated in cancer and/or their phosphorylation is known to affect (or is affected) by the DDR. We designed biotinylated 20 amino acid (aa) peptides encompassing the specific phosphorylated amino acids of BRCA1, RAD50, MLH1 and XPC that were either non-phosphorylated or phosphorylated. The biotinylated peptides were coupled to streptavidin beads and used to pull down proteins from HeLa nuclear extracts. Proteomic analysis revealed that all four sites bind proteins in a phospho-dependent manner. Each of the phosphorylated sites were binding various proteins including those implicated in DDR and cell cycle regulation as well as proteins involved in other cellular processes; some of these proteins have already known phospho-binding domains, while others do not. Interestingly, microtubule associated protein MAP7 featured prominently in all of the phosphorylated RAD50, BRCA1, MLH1 and XPC peptide pull-downs and MAP7 paralogue MAP7D1 also featured in the phosphorylated BRCA1 peptide pull-down. In the rest of the project we study the interactions and their function in DNA repair.
