Quantitative analysis of SUMO1 and SUMO2 proteomes in human lung A549 cells during influenza A virus infection or heat-shock

ABSTRACT: Dynamic nuclear SUMO modifications play essential roles in orchestrating cellular responses to proteotoxic stress, DNA damageand DNA virus infections. Here, we describe the host SUMOylation response to the nuclear-replicating RNA pathogen, influenz A virus. Using quantitative proteomics to compare SUMOylation responses to various stresses (including heat-shock), we reveal that influenza A virus infection causes unique re-targeting of SUMO1 and SUMO2 to a diverse range of host proteins involved in transcription, mRNA processing, RNA quality control and DNA damage repair. This global characterization of influenza virus-triggered SUMO remodeling provides a proteomic resource to understand host nuclear SUMOylation responses to infection.

Dynamic nuclear SUMO modifications play essential roles in orchestrating cellular responses to proteotoxic stress, DNA damage, and DNA virus infection. Here, we describe a non-canonical host SUMOylation response to the nuclear-replicating RNA pathogen, influenza virus, and identify viral RNA polymerase activity as a major contributor to SUMO proteome remodeling. Using quantitative proteomics to compare stress-induced SUMOylation responses, we reveal that influenza virus infection triggers unique ...[more]

NuA4 and H2A.Z control environmental responses and autotrophic growth in Arabidopsis

Project description:Nucleosomal acetyltransferase of H4 (NuA4) is an essential transcriptional coactivator in eukaryotes, but remains poorly characterized in plants. Here, we describe Arabidopsis homologs of the NuA4 scaffold proteins Enhancer of Polycomb-Like-1 (AtEPL1) and Esa1- Associated Factor 1 (AtEAF1). Loss of AtEAF1 results in inhibition of growth and chloroplast development. These effects are stronger in the Atepl1 mutant and are further enhanced by loss of Golden2-Like (GLK) transcription factors, suggesting that NuA4 activates nuclear plastid genes alongside GLK. We demonstrate that AtEPL1 is necessary for nucleosomal acetylation of histones H4 and H2A.Z by NuA4 in vitro. These chromatin marks are diminished genome-wide in Atepl1, while another active chromatin mark, H3K9 acetylation (H3K9ac), is locally enhanced. Expression of many chloroplast-related genes depends on NuA4, as they are downregulated with loss of H4ac and H2A.Zac. Finally, we demonstrate that NuA4 promotes H2A.Z deposition and by doing so prevents spurious activation of stress response genes.

Characterizations of HSP90-interacting complex in renal cells using tandem affinity purification and its potential role in kidney stone formation

Project description:Heat shock protein 90 (HSP90) is a highly abundant molecular chaperone that interacts with many other intracellular proteins to regulate various cellular processes. However, compositions of the HSP90-interacting complex remain underinvestigated. This study thus aimed to characterize such complex in human embryonic kidney (HEK293T) cells under normal physiologic state using tandem affinity purification (TAP) followed by protein identification using an ultrahigh-resolution tandem mass spectrometer (Qq-TOF MS/MS). A total of 32 proteins, including four forms of HSP90 and 16 novel HSP90-interacting partners, were successfully identified from this complex using TAP control to subtract non-specific binders. Co-immunoprecipitation followed by immunoblotting and immunofluorescence co-staining confirmed the association of HSP90 with known (HSP70, α-tubulin, and β-actin) and novel (vimentin, calpain-1, and importin-β1) partners. Knockdown of HSP90 by small-interfering RNA (siHSP90) caused significant changes in levels of HSP70, α-tubulin, β-actin, vimentin, and calpain-1, all of which are calcium oxalate (CaOx) crystal-binding proteins that play significant roles in kidney stone formation. Moreover, crystal-binding capability was significantly decreased in siHSP90-transfected cells as compared to non-transfected control and siControl-transfected cells. In summary, we report herein a number of novel HSP90-interacting proteins in renal cells and demonstrate the potential role of HSP90-interacting complex in kidney stone formation.

The Global Landscape of Transcription Initiation During the Caulobacter Cell Cycle [mapping]

Project description:The Caulobacter cell cycle includes in an asymmetric cell division that is driven by a core regulatory circuit comprised of 4 transcription factors (DnaA, GcrA, CtrA, and SciP) and a DNA methyltransferase (CcrM). Using a modified global 5M-bM-^@M-^Y RACE protocol we mapped 2,726 transcriptional start sites (TSS) in the 4mb Caulobacter genome and identified 586 cell cycle-regulated TSS. The core cell cycle circuit directly controls about 55% of cell cycle-regulated TSS by integrating multiple regulatory inputs within at least 322 promoters, providing a large number of transcription profiles from a small number of regulatory factors. Here, we identified previously unknown features of the core cell cycle circuit, including antisense TSS within dnaA and ctrA, plus newly identified TSS for ctrA and ccrM. Altogether, we identified 615 antisense TSS plus 241 genes that are transcribed from multiple TSS. The multiple TSS in the same promoter region often exhibit different cell cycle activation timing, These novel features of the global transcript profile add significant insight to the system architecture of the Caulobacter cell cycle regulatory circuit. Global 5' RACE was performed to map Transcription Start Sites in the Caulobacter NA1000 genome

Nucleolar-nucleoplasmic shuttling of the RNA-binding macrodomain-containing TARG1 is controlled by DNA damage-induced poly-ADP-ribose and implies functions in ribosome biogenesis

Project description:In this project we employed affinity purification mass spectrometry to determine the interactome of the macrodomain containing protein TARG1/OARD1. TARG1 functions as a hydrolase towards mono-ADP-ribosylation (MARylation). TARG1 sowed strong binding to ribosomes and proteins associated with rRNA processing. However, when poly-ADP- ribosylation (PARylation) was present in the cellular lysate, TARG1 was found to interacts with DNA repair and chromatin-associated proteins, including ARTD1, in a PARylation-dependent manner. PARylation events also lead to a change in the subcellular localization of TARG1, which was found to reside in the nucleolus in resting cells, and shuttle to the nucleoplasm upon PARylation

TraB is a component of the ER-Mitochondrial contact site regulating ER-Mitochondrial interaction and mitophagy

Project description:ER-mitochondria contact sites (EMCSs) are important for mitochondrial function. Here, we have identified a EMCS complex, comprising a family of uncharacterised mitochondrial outer- membrane proteins, TraB1, TraB2 and the ER protein, VAP27-1. In Arabidopsis, there are three TraB isoforms and the trab1a/trab2 double mutant exhibits abnormal mitochondrial morphology, strong starch accumulation and impaired energy metabolism, indicating that these proteins are essential for normal mitochondrial function. Moreover, TraB1 and TraB2 proteins also interact with ATG8 in order to regulate mitochondrial degradation (mitophagy). The turnover of depolarised mitochondria is significantly reduced in both trab1/trab2 and VAP27 mutants (vap27-1,3,4,6) under mitochondrial stress conditions, with an increased population of dysfunctional mitochondria present in the cytoplasm. Consequently, plant recovery after stress is significantly perturbed, suggesting that TraB1 regulated mitophagy and ER-mitochondrial interaction are two closely related processes. Taken together, we ascribe a dual role to TraB1 which is a component of the EMCS complex in eukaryotes, regulating both interaction of the mitochondria to the ER and mitophagy.

Architecture of the chromatin remodeler RSC and insights into its nucleosome engagement

Project description:Eukaryotic DNA is packaged into nucleosome arrays, which are repositioned by chromatin remodeling complexes to control DNA accessibility. The Saccharomyces cerevisiae RSC (Remodeling the Structure of Chromatin) complex, a member of the SWI/SNF chromatin remodeler family, plays critical roles in genome maintenance, transcription, and DNA repair. Here, we report cryo-electron microscopy (cryo-EM) and crosslinking mass spectrometry (CLMS) studies of yeast RSC complex and show that RSC is composed of a rigid tripartite core and two flexible lobes. The core structure is scaffolded by an asymmetric Rsc8 dimer and built with the evolutionarily conserved subunits Sfh1, Rsc6, Rsc9 and Sth1. The flexible ATPase lobe, composed of helicase subunit Sth1, Arp7, Arp9 and Rtt102, is anchored to this core by the N-terminus of Sth1. Our cryo-EM analysis of RSC bound to a nucleosome core particle shows that in addition to the expected nucleosome-Sth1 interactions, RSC engages histones and nucleosomal DNA through one arm of the core structure, composed of the Rsc8 SWIRM domains, Sfh1 and Npl6. Our findings provide structural insights into the conserved assembly process for all members of the SWI/SNF family of remodelers, and illustrate how RSC selects, engages, and remodels nucleosomes.

Mapping the protein interaction network of adaptor protein complex in Arabidopsis identifies P34 as a common stability regulator

Project description:Adaptor protein (AP) complexes are evolutionarily conserved vesicle transport regulators that recruit coat proteins, membrane cargos and coated vesicle accessory proteins. Since in plants endocytic and post-Golgi trafficking intersect at the trans-Golgi network, unique mechanisms for sorting cargos of overlapping vesicular routes are anticipated. The plant AP complexes are part of the sorting machinery, but despite some functional information, their cargoes, accessory proteins, and regulation remain largely unknown. Here, by means of various proteomics approaches, we generated the overall interactome of the five AP and the TPLATE complexes in Arabidopsis thaliana. The interactome converged on a number of hub proteins, including the thus far unknown adaptin binding-like protein, designated P34. P34 interacted with the clathrin-associated AP complexes, controlled their stability and, subsequently, influenced clathrin-mediated endocytosis and various post-Golgi trafficking routes. Altogether, the AP interactome network offers substantial resources for further discoveries of unknown endomembrane trafficking regulators in plant cells.
