WebHox-CTCF link across the Bilateria. On the basis of these ﬁndings, we propose the existence of a Hox-CTCF kernel as principal orga-nizer of bilaterian body plans. Such a kernel could explain (i) the formation of Hox clusters in Bilateria, (ii) the diversity of bilaterian body plans, and (iii) the uniqueness and time of onset of the Cam- WebDeletion of CTCF binding sites within the Hox clusters results in the expansion of active chromatin into the repressive domain.
