ProteomicsDrosophila SWR1 and NuA4 complexes are defined by DOMINO isoform
Histone acetylation and deposition of H2A.Z variant are integral aspects of active transcrip-tion. In Drosophila, the single DOMINO chromatin regulator complex is thought to combine both activities via an unknown mechanism. Here we show that alternative isoforms of the DOMINO nucleosome remodeling A...

ProteomicsDivergent evolutionary strategies for selective sex chromosome regulation in Drosophila
The dosage compensation complex (DCC) of Drosophila identifies its X chromosomal binding sites with exquisite selectivity. The principles that assure this vital targeting are known from the D. melanogaster model: DCC-intrinsic specificity of DNA binding, cooperativity with the CLAMP protein, and non...

TranscriptomicsThe activation potential of MOF is constrained for dosage compensation
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 ...

GenomicsActive Promoters give rise to false positive 'Phantom Peaks' in ChIP-Seq experiments
We applied ChIP-seq to map the chromosomal binding sites for two nucleosome remodeling complexes containing the ATPase ISWI, ACF and RSF, in Drosophila embryos. Employing a panel of polyclonal and monoclonal antibodies directed against their signature subunits, ACF1 and RSF1, robust profiles were ob...

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

TranscriptomicsThe MOF-containing NSL complex associates globally with housekeeping genes, but activates only a defined subset
This SuperSeries is composed of the following subset Series: GSE30989: MOF-containing NSL complex specifically binds promoters of most, but stimulates only a specific subset of, housekeeping genes (ChIP-chip dataset) GSE30990: MOF-containing NSL complex specifically binds promoters of most, but stim...

TranscriptomicsThe nucleosome remodeler SNF2L modulates WNT signaling for cellular homeostasis
ISWI is an evolutionary conserved ATPase that catalyzes nucleosome remodeling in several different complexes. Two mammalian ISWI orthologs, SNF2H and SNF2L, have specialized functions despite their high similarity. Due to the lack of reagents the functions of SN2L in human cells had not been establi...

TranscriptomicsAnalysis of genome-wide binding of the insulator factors CTCF and CP190
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 e...
