Hox proteins are transcription factors that control developmental pathways along the anteroposterior axis of vertebrates. On their own, Hox proteins bind DNA weakly, but they gain specificity and affinity by interaction with members of the PBC subfamily of homeobox proteins. In vitro studies indicate that most of these interactions are mediated by the conserved hexapeptide motif of the Hox proteins. To study the significance of these interactions in vivo, we have generated mice that carry… Expand
