title: Gag order.
abstract: The Polycomb group (PcG) complex mediates heritable silencing of numerous genes during development. In a recent issue of Molecular Cell, Wang et al. (2004) characterize the order of PcG protein recruitment to specific regions of Ubx and substantiate a binding-in trans looping model of repression that may interfere with transcription initiation or elongation.
