Genome-wide binding of Ubx and Hth in 3rd thoracic imaginal discs

ABSTRACT: The Hox genes are responsible for generating morphological diversity along the anterior-posterior axis during animal development. The Drosophila Hox gene Ultrabithorax (Ubx), for example, is required for specifying the identity of the third thoracic (T3) segment of the adult, which includes the dorsal haltere, an appendage required for flight, and the ventral T3 leg. Ubx mutants show homeotic transformations of the T3 leg towards the identity of the T2 leg and the haltere towards the wing. All Hox genes, including Ubx, encode homeodomain containing transcription factors, raising the question of what target genes Ubx regulates to generate these adult structures. To address this question, we carried out whole genome ChIP-chip studies to identify all of the Ubx bound regions in the haltere and T3 leg imaginal discs, which are the precursors to these adult structures. In addition, we used ChIP-chip to identify the sites bound by the Hox cofactor, Homothorax (Hth). This is a dataset generated by the Drosophila Regulatory Elements modENCODE Project led by Kevin P. White at the University of Chicago. This dataset was generated in collaboration with Richard S. Mann at Columbia University. It contains ChIP-chip data on Affymetrix Drosophila Tiling 2.0R arrays for multiple transcription factor antibodies in multiple Drosophila tissues.

For each combination of tissue and antibody, ChIP experiments have been performed and hybridized on Affymetrix Drosophila Tiling 2.0R arrays. At least 3 biological replicates for the ChIP sample have been hybridized.
