Painting of fourth and chromosome-wide regulation of the 4th chromosome in Drosophila melanogaster.

The EMBO journal 20070222 9
Drosophila melanogaster exhibits two expression-regulating systems that target whole, specific chromosomes: the dosage compensation system whereby the male-specific lethal complex doubles transcription of genes on the male X-chromosome and the chromosome 4-specific protein Painting of fourth, POF. POF is the first example of an autosome-specific protein and its presence raises the question of the universality of chromosome-specific regulation. Here we show that POF and heterochromatin protein 1 ...[more]

Project description:Analysis of gene expression in pof deletion mutants. Chromosome 4 genes are down-regulated in pof mutants compared to wildtype control. 200 Drosophila melanogaster first instar larvae were used for each of three biological replicates of y1 w67c23; PofD119/PofD119 and three biological replicates of y1 w67c23 as controls. Experiment Overall Design: 200 1st instar larvae were used for each of 3 biological replicates of pof mutants and 3 replicates of wt larvae.

Project description:modENCODE_submission_3794 This submission comes from a modENCODE project of Gary Karpen. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: We aim to determine the locations of 125 chromosomal proteins across the Drosophila melanogaster genome. The proteins under study are involved in basic chromosomal functions such as DNA replication, gene expression, gene silencing, and inheritance. We will perform Chromatin ImmunoPrecipitation (ChIP) using genomic tiling arrays. We will initially assay localizations using chromatin from three cell lines and two embryonic stages, and will then extend the analysis of a subset of proteins to four additional animal tissues/stages 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-chip.
