Hat1-Dependent Lysine Acetylation Targets Diverse Cellular Functions.

Agudelo Garcia Paula A PA Nagarajan Prabakaran P Parthun Mark R MR

Journal of proteome research 20200304 4

Lysine acetylation has emerged as one of the most important post-translational modifications, regulating different biological processes. However, its regulation by lysine acetyltransferases is still unclear in most cases. Hat1 is a lysine acetyltransferase originally identified based on its ability to acetylate histones. Using an unbiased proteomics approach, we have determined how loss of Hat1 affects the mammalian acetylome. Hat1<sup>+/+</sup> and Hat1<sup>-/-</sup> mouse embryonic fibroblast ...[more]

Identification of NEDD8 sites at endogenous levels of NEDD8 expression upon NEDP1 (SENP8, DEN1) knockout.

Project description:We developed a strategy that allows the identification of NEDP1 dependent NEDDylation sites under endogenous expression of wild type NEDD8. We combined the use of anti-diGly antibodies that recognise both ubiquitin and NEDD8 modified peptides upon trypsin digestion with short treatment of cells with the ubiquitin E1 inhibitor MLN7243 (UAEi), that dramatically reduces ubiquitin but not NEDD8 modification. By eliminating the majority of ubiquitin-derived diGly peptides upon MLN7243 treatment, we would be able to quantify NEDP1 dependent diGly peptides. Extracts from parental and NEDP1 knockout HCT116 cells both treated with UAEi were used for the isolation of diGly modified peptides and mass spectrometry analysis.

Germline maintenance through the multifaceted activities of GLH/Vasa in Caenorhabditis elegans P granules

Project description:Vasa is a highly conserved member of the ATP-dependent DEAD box helicase family, a multipotency factor, and a critical component for the specification and maintenance of the germline. Its homologs have been shown to regulate translation, small RNA amplification, and serve as a molecular solvent for single-stranded RNA; however, the function of Vasa’s defining domains and what they interact with are unclear. To address this, 28 mutant alleles of the C. elegans Vasa homolog GLH-1 were generated in conserved motifs. Mutations in the flanking and helicase domains show that GLH-1 retains its association with P granules through its helicase activity and not through static interactions with other P-granule proteins. Changes outside of these domains retain GLH-1 in P granules but still compromise fertility, and removal of glycine-rich repeats progressively diminish P-granule wetting-like interactions at the nuclear periphery. A mutation that facilitates Vasa aggregation was previously leveraged in insects and mammals to identify the transient association of Vasa with piRNA amplifying Argonautes. This same mutation in GLH-1 also stimulates aggregation and association with Argonautes, suggesting that the transient amplifying complex is evolutionarily conserved even though the method of piRNA amplification in C. elegans is not. Mass spectrometry analysis of proteins that co-immunoprecipitate with wild type and mutant GLH-1 reveal an affinity for all three PCI (26S Proteasome Lid, COP9, eIF3) scaffolding complexes, which regulate protein turnover and translation, and an aversion for ribosomes and the 26S proteasome core. These results suggest that phase-separated P granules compartmentalize the cytoplasm to exclude large protein assemblies and emphasize the role of Vasa homologs in maintaining proteostasis.

Combined Metabolic and Chemical (CoMetChem) labeling using stable isotopes

Project description:Histone acetylation is an important, reversible posttranslational protein modification and hallmark of epigenetic regulation. However, little is known about the dynamics of reversible hisotne acetylation, due to the lack of analytical methods that can capture site-specific acetylation and deacetylation reactions. We present a new approach that combines metabolic and chemical labeling (CoMetChem) using uniformly 13C-labeled glucose and stable isotope labeled acetic anhydride, which allows to quantify site-specific lysine acetylation dynamics in tryptic peptides using high-resolution mass spectrometry.

Dysregulated cellular redox status during hyperammonemia causes mitochondrial dysfunction by inhibiting sirtuin mediated deacetylation

Project description:Perturbed metabolism of ammonia, an endogenous cytotoxic molecule, causes mitochondrial dysfunction with decreased nicotinamide adenine dinucleotide (NAD+) in skeletal muscle. Consistent with our previous report of enrichment of NAD metabolism and sirtuin pathways during hyperammonemia, NAD+-dependent Sirtuin3 (Sirt3) expression and deacetylase activity weredecreased with increased muscle protein acetylation in murine and human skeletal muscle/myotubes. Acetylomics and cell fractions showed hyperammonemia-induced hyperacetylation of critical mitochondrial and signaling molecules. Overexpression of mitochondrial targeted Lactobacillus brevis NADH oxidase (MitoLbNOX) reversed ammonia-induced oxidative dysfunction, electron transport chain (ETC) supercomplex disassembly, lower ATP content, NAD+, and redox ratio (NAD+/NADH). Protein hyperacetylation, post-mitotic senescence and lower mitochondrial sirtuin (Sirt3) expressionduring hyperammonemia were also reversed by MitoLbNOX. Sirt3 overexpression alone did not reverse ammonia-induced redox or mitochondrial dysfunction but reversed hyperacetylation and senescence. These data show that targeting redox ratio, rather than Sirt3, more consistently restores mitochondrial homeostasis and protein acetylation during hyperammonemia.

Quantifying Competition Among Mitochondrial Protein Acylation Events Induced by Ethanol Metabolism

Project description:Mitochondrial dysfunction is one of many key factors in the etiology of alcoholic liver disease (ALD). Lysine acetylation is known to regulate numerous mitochondrial metabolic pathways and recent reports demonstrate that alcohol-induced protein acylation negatively impacts these processes. To identify regulatory mechanisms attributed to alcohol-induced protein post-translational modifications, we employed a model of alcohol consumption within the context of wild type (WT), sirtuin 3 knockout (SIRT3 KO), and sirtuin 5 knockout(SIRT5 KO) mice to manipulate hepatic mitochondrial protein acylation. Mitochondrial fractions were examined by label-free quantitative HPLC-MS/MS to reveal competition between lysine acetylation and succinylation. A class of proteins defined as “differential acyl switching proteins” demonstrate select sensitivity to alcohol-induced protein acylation. A number of these proteins reveal saturated lysine-site occupancy, suggesting a significant level of differential stoichiometry in the setting of ethanol consumption. We hypothesize that ethanol downregulates numerous mitochondrial metabolic pathways through differential acyl switching proteins.

Proteogenomics of ex vivo-activated platelets.

Project description:Platelets are major players in the process of intravascular thrombus formation. Current therapeutic strategies still fail to prevent thrombotic coronary events in a substantial number of patients, indicating that the complex mechanisms modulating platelet response during activation are not fully elucidated. The evidence that platelets are capable of de novo protein synthesis has raised the issue of whether and how these resident mRNAs are regulated in circulating platelets. Among the several mechanisms potentially involved, mRNA splicing may be relevant. Purified platelet-rich plasmas from healthy volunteers were collected and in vitro activated with collagen or Thrombin Receptor Activating Peptide (TRAP). Transcriptome profiling by RNA-Seq and in silico intron representation analysis were applied to search for the presence of pre-mRNA molecules and splicing events affected by platelet activation. HiRIEF LC-MS allowed platelet proteome characterization at deep coverage to investigate a possible correlation between splicing events and protein levels. By comparing computational and wet-lab analyses it was possible to identify a set of transcripts influenced at both intron and protein level.
