WebHox proteins are sequence-specific DNA binding proteins. They recognize small, 4–5 base regions that are AT rich, often with a core of TAAT. Furthermore, they interact with other DNA-binding “cofactors,” and when partnered with a cofactor have a larger and, therefore, more specific DNA binding site. WebMainly Hox genes of the HoxA and HoxC clusters are expressed in MNs with initial overlapping boundaries, which later on become refined. The establishment of these …
