Hox-related factors
Web6 mrt. 2014 · Hox genes encode homeodomain-containing transcription factors that determine cell and tissue identities in the embryo during development. Hox genes are also expressed in various adult tissues and cancer cells. In Drosophila , expression of cell adhesion molecules, cadherins and integrins, is regulated by Hox proteins operating in … 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.
