Analysis of genome-wide binding of the insulator factors CTCF and CP190

Project description:We identified about 3000 CTCF sites in the genome. In addition to binding to CTCF sites we found CP190 to bind to transcriptional start sites of actively transcribed genes where it inversely correlates with nucleosome occupancy. Keywords: ChIP-chip CTCF and CP190 ChIP. 2 biological replicates per experiment. dye-swaps as indicated in sample description.

The activation potential of MOF is constrained for dosage compensation

Project description:The H4K16 acetyltransferase MOF plays a crucial role in dosage compensation in Drosophila, but has additional, global functions. We compared the molecular context and effect of MOF in male and female flies combining chromosome-wide mapping and transcriptome studies with analyses of defined reporter loci in transgenic flies. MOF distributes dynamically between two complexes, the Dosage Compensation Complex and a complex containing MBD-R2, a global facilitator of transcription. These different targeting principles define the distribution of MOF between the X chromosome and autosomes and at transcription units with 5’ or 3’ enrichment. The male X chromosome differs from all other chromosomes in that H4K16 acetylation levels do not correlate with transcription output. The reconstitution of this phenomenon at a model locus revealed that the activation potential of MOF is constraint in male cells in the context of the DCC to arrive at the two-fold activation of transcription characteristic of dosage compensation. ChIP-chip profiling of MBD-R2, MOF and MSL1 in adult male and female flies, and SL2 cells, incl. at least 3 biological replicates

The MOF-containing NSL complex associates globally with housekeeping genes, but activates only a defined subset (ChIP)

Project description:The MOF-containing NSL complex binds to many but not all promoters of active genes and potentially contributes to their proper gene expression. It is currently unknown what determines whether an active gene is bound or not. Here, we provide evidence that the NSL complex primarily targets active promoters of most housekeeping genes. There, it co-localizes with the chromatin remodeler NURF and the histone methyltransferase Trithorax. Moreover, despite binding to most housekeeping genes, the NSL complex regulates only a subset of them, which are depleted for certain insulator binding-proteins and enriched for the core promoter motif “Ohler 5”. We suggest that the combination of general chromatin factors and core promoter motifs is predictive for whether a housekeeping gene is transcriptionally regulated by the NSL complex. ChIP-chip profiling of NSL1 in adult male and female whole fly extracts and the embryonically derived male S2 cell line.

Genome-associated RNA Polymerase II includes the dissociable Rpb4/7 subcomplex

Project description:Yeast RNA polymerase (Pol) II consists of a ten-subunit core enzyme and the Rpb4/7 subcomplex, which is dispensable for catalytic activity and dissociates in vitro. To investigate whether Rpb4/7 is an integral part of DNA-associated Pol II in vivo, we used chromatin immuno-precipitation coupled to high-resolution tiling microarray analysis. We show that the genome-wide occupancy profiles for Rpb7 and the core subunit Rpb3 are essentially identical. Thus, the complete Pol II associates with DNA in vivo, consistent with functional roles of Rpb4/7 throughout the transcription cycle. Keywords: ChIP-chip Comparison of Rpb3 vs. Rpb4/7 genome-wide occupancy profiles. Data obtained from independent ChIP-chip experiments on two yeast strains: S288C Rpb3TAP vs. Rpb7-TAP strain and W303 Rpb3-TAP vs. wild type strain (IP with the monoclonal antibody for Rpb4/7). Biological replicates W303 strains: 1 x Rpb3-TAP, 1 x wt with Rpb4/7 antibody, independently grown and harvested. Biological replicates S288C strains: 3 x Rpb3-TAP, 2 x Rpb7-TAP, independently grown and harvested. One replicate per array.
