The Hox genes are clustered sets of homeobox-containing genes that play a central role in animal development. Recent genetic and molecular data suggest that Hox proteins interact with pre-existing homeodomain protein complexes. These complexes may help to regulate Hox activity and Hox specificity, and help cells to interpret signaling cascades during development.
