title: Hox proteins: sculpting body parts by activating localized cell death.
abstract: Hox proteins shape animal structures by eliciting different developmental programs along the anteroposterior body axis. A recent study reveals that the Drosophila Hox protein Deformed directly activates the cell-death-promoting gene reaper to maintain the boundaries between distinct head segments.
