We find a high concordance between the binding of the Drosophila transcription factor Dorsal and the co-activator CBP during early embryogenesis. This relationship was furter examined by comparing CBP distribution in Drosophila embryos derived from wt and mutant flies lacking intranuclear Dorsal (gd7). Our data suggests a specific involvemet of CBP in initiating early dorsoventral patterning, but not in anterioposterior. CBP ChIP seq of 2-4 hours old Drosophila embryos derived from w1118 (wild-type) or gd7 homozygous mutant mothers

We profiled Sex comb on midleg (Scm), Pc and E(z) in fly embryos and S2 based on BioTAP-XL ChIP-seq. ChIP-seq revealed that Scm is co-localized with PRC1, PRC2, and H3K27me3 in both S2 cells and embryos. Genomic binding/occupancy profiling of Scm, Pc and E(z) by high throughput sequencing

LID is a histone demethylase acting on H3K4me3, a mark related to transcription and found near the transcription start sites (TSS) of the genes. We analyzed where POLIISER5 and POLIISER2 are localized in LID RNAi mutants. 1 sample for POLIISER5 with an input control, and 1 sample for POLIISER2 with an input control.

modENCODE_submission_3628 This submission comes from a modENCODE project of David MacAlpine. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: We will precisely identify sequence elements that direct DNA replication by using chromatin immunoprecipitation of known replication initiation complexes. These experiments will be conducted in multiple cell types and developmental tissues. For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf EXPERIMENT TYPE: CHIP-seq. BIOLOGICAL SOURCE: Developmental Stage: Embryo 0-2h; EXPERIMENTAL FACTORS: Developmental Stage Embryo 0-2h; Antibody dORC2 (target is Drosophila ORC2p); read length (read_length)

We report genome-wide binding of the highly conserved TF Sine oculis (So), which is necessary for Drosophila eye development and has few previously known direct transcriptional targets. Our data identify novel putative targets of So-mediated regulation, including genes involved in multiple aspects of development. 2 biological replicates of ChIP-seq with anti-So antibody on chromatin from D. melanogaster third instar eye-antennal imaginal discs; negative control - same sample and ChIP-seq protocol without anti-So antibody

Trithorax group (TrxG) proteins counteract Polycomb silencing by an as yet uncharacterized mechanism. A well-known member of the TrxG is the histone methyltransferase Absent, Small, or Homeotic discs 1 (ASH1). In Drosophila ASH1 is needed for the maintenance of Hox gene expression throughout development, which is tightly coupled to preservation of cell identity. In order to understand the molecular function of ASH1 in this process, we performed affinity purification of tandem-tagged ASH1 followed by mass spectrometry (AP-MS) and identified FSH, another member of the TrxG as interaction partner. Here we provide genome-wide chromatin maps of both proteins based on ChIP-seq. Our Dataset comprises of 4 ChIP-seq samples using chromatin from S2 cells which was immunoprecipitated, using antibodies against Ash1, FSH-L and FSH-SL.

JAK/STAT pathway plays important roles in controlling Drosophila intestinal homeostasis and regulating the ISC proliferation and differentiation. However,the downstream targets of its transcription factor-STAT92E remain largely unknown.To further identify the regualtory mechanisms of the JAK/STAT pathway in controlling intestinal homeostasis,we performed the ChIP-Seq assay with mouse raised STAT92E antibody using JAK/STAT signaling highly activated adult intestines.Through the ChIP assay, we have identified over 1000 significant peaks (p<0.01) around the putative targets.The well-characterized JAK/STAT downstream targets including Domeless,Socs36E,STAT92E and chinmo were identified in our ChIP assay,indicating that our experiment is workable to identify novel JAK/STAT downstream targets in adult intestines.This work will provide insights into our understanding of regulatory mechanisms of JAK/STAT signaling during Drosophila intestinal development. Identify the ChIP peaks of STAT92E antibody using JAK/STAT signaling highly actived Drosophila adult intestines, compared with input libaray as the control

We show that the non-specific lethal (NSL) complex in Drosophila binds to housekeeping genes. Individual ChIP-qPCR experiments of NSL target genes indicated a role of the NSL complex in RNA Polymerase II (Pol II) recruitment to promoters. Consequently, we obtained ChIP-Seq profiles of the Pol-II-subunit Rbp3 in S2 cells that were depleted of either NSL1 or NSL3. Rbp3-ChIP from S2 cells treated with siRNA targeted against GFP were used as a control. This experiment is related to experiment E-MTAB-214 and E-MTAB-1085.
