In contrast to our extensive knowledge on covalent small ubiquitin-like modifier (SUMO) target proteins, we are limited in our understanding of non-covalent SUMO-binding proteins. We identify interactors of different SUMO isoforms-monomeric SUMO1, monomeric SUMO2, or linear trimeric SUMO2 chains-using a mass spectrometry-based proteomics approach. We identify 379 proteins that bind to different SUMO isoforms, mainly in a preferential manner. Interestingly, XRCC4 is the only DNA repair protein in ...[more]

ChIP-Seq of Myf5, MyoD, Snai1, HDAC1, HDAC2, E47 and empty vector controls in mouse skeletal myoblasts or myotubes

Project description:In skeletal myogenesis, the transcription factor MyoD activates distinct transcriptional programs in progenitors compared to terminally differentiated cells. Using ChIP-seq and gene expression analyses, we show that in primary myoblasts, Snail-HDAC1/2 repressive complex bind and exclude MyoD from its targets. Notably, Snail binds E-box motifs that are G/C-rich in their central dinucleotides, and such sites are almost exclusively associated with genes expressed during differentiation. By contrast, Snail does not bind the A/T-rich E-boxes associated with MyoD targets in myoblasts. Thus, Snai1-HDAC1/2 prevents MyoD occupancy on differentiation-specific regulatory elements and the change from Snail- to MyoD-binding often results in enhancer switching during differentiation. Furthermore, we show that a regulatory network involving Myogenic Regulatory Factors (MRFs), Snail/2, miR-30a and miR-206 acts as a molecular switch that controls entry into myogenic differentiation. Together, these results reveal a regulatory paradigm that directs distinct gene expression programs in progenitors versus terminally differentiated cells.

Mapping the DNA-binding response regulators of Desulfovibrio vulgaris Hildenborough

Project description:D. vulgaris is a model sulfate reducing bacteria whose genome encodes a high number of two component systems, including 29 DNA-binding response regulators (RRs) whose functions are unknown, but are very likley to be important to the environmental lifestyle of the organism. We determined the gene targets for 24 of these RRs using purified His-tagged RR and sheared genomic DNA in an in vitro DAP-chip (DNA-affinity-purified - chip) assay. For each RR, one target was identified first using gel shift assays, and qPCR was used to ensure that the target was enriched in the RR-bound DNA before the samples were hybridized to a tiling array. Based on the peaks generated by the array analysis, we determined that at least 200 genes are regulated by two component systems in this organism. We also predicted binding site motifs and validated them for 15 RRs using gel shift assays. In vitro DAP-chip for 28 response regulators where RR-bound enriched DNA is compared to input total genomic DNA

Receptor-mediated recruitment of cytosolic J-proteins to the mitochondrial outer membrane promotes assembly of preprotein translocases

Project description:Mitochondria possess elaborate machineries for the import of preproteins from the cytosol. Cytosolic factors like Hsp70 chaperones and their co-chaperones, the J-proteins, guide preproteins to the mitochondrial surface. The translocase of the mitochondrial outer membrane (TOM) forms the entry gate for precursor proteins. How proteins are delivered to the receptors Tom20, Tom22 and Tom70 is only understood in part. We identified the cytosolic J-protein Xdj1 as a specific interaction partner of the central receptor Tom22. Tom22 recruits Xdj1 to the mitochondrial surface to promote assembly of the TOM complex. A second J-protein of the cytosol, Djp1, binds to Tom70 to mediate biogenesis of the mitochondrial import (MIM) complex. Thus, by targeting distinct TOM receptors, cytosolic J-proteins promote the biogenesis of different mitochondrial preprotein translocases.

Chromatin Affinity Precipitation-chiop of B. subtilis to gain insight into the invivo dynamics of RNA polymerase

Project description:To obtain an insight into the in vivo dynamics of RNA polymerase (RNAP) on the B. subtilis genome, we analyzed the distribution of ?A and ? subunits of RNAP and the NusA elongation factor on the genome in exponentially growing cells, using the ChAP (Chromatin Affinity Precipitation)-chip method. In contrast to E. coli RNAP, which often accumulates at the promoter-proximal region, B. subtilis RNAP is evenly distributed from the promoter to the coding sequences in the majority of genes. This finding suggests that B. subtilis RNAP recruited to the promoter promptly translocates away from the promoter to form the elongation complex. We detected RNAP accumulation in the promoter-proximal regions of some genes, most of which are attributed to transcription attenuation systems in the leader region. Our findings suggest that the differences in RNAP behavior during initiation and early elongation steps between E. coli and B. subtilis result in distinct strategies for post-initiation control of transcription. The E. coli mechanism involves trapping at the promoter and promoter-proximal pausing of RNAP in addition to transcription attenuation, whereas transcription attenuation in leader sequences is mainly employed in B. subtilis. Wild-type strain, Bacillus subtilis 168, was also used for RNA and genomic DNA extraction and analysis - RNA data was divided by genome DNA data to normalize (1) PCR bias and (2) copy number of RNA molecule per genome for multi-copy genome of exponentially growing bacteria.
