Status Public on Jul 29, 2009
Title S2-DRSC Replication Origins
Project modENCODE
Organism Drosophila melanogaster
Experiment type Other
Summary modENCODE_submission_710
This submission comes from a modENCODE project of David MacAlpine. For full list of modENCODE projects, see http://www.genome.gov/26524648
Project Goal: Early origins of replication were identified by treating cells with hydroxyurea (HU), a potent inhibitor of nucleotide synthesis, in the presence of the nucleotide analogue BrdU. Treatment of synchronized S2-DRSC cells with HU stalls replication forks and activates the intra S-phase checkpoint, thereby limiting BrdU incorporation to those sequences immediately adjacent to early activating replication origins. BrdU enriched sequences surrounding early origins of replication are then enriched by immunoprecipitation with an anti-BrdU antibody. Early origins are then detected by hybridization to Agilent genomic tiling arrays. Peaks are called using MA2C (http://liulab.dfci.harvard.edu/MA2C/MA2C.htm)
