Mapping dynamic Polycomb group proteins during Drosophila development
...intained at all times, other PcG protein locations varied considerably, implying that PcGs employ dynamic regulation over time. In fact, adult male flies had the most divergent profile of PcG Response Elements (the region of chromatin where the PcG proteins bind), suggesting that some male-specific developm...Children's Hospital Boston presents at the 2006 Pediatric Academic Societies annual meeting
