Although Hox genes contain and are originally named because of the homeobox sequence, not all homeobox-containing genes are Hox genes (other examples include the POU genes and CDX genes). The homeobox encodes for a protein sequence called the homeodomain, which is a DNA-binding domain.
Hox genes are a group of related genes that control the body plan of an embryo along the head-tail axis. After the embryonic segments have formed, the Hox proteins determine the type of appendages or the different types of vertebrae that will form on a segment. Hox proteins thus confer segmental identity, but do not form the actual segments themselves. The term Hox itself is a contraction of homeobox, in the field of genetics. An analogy for the Hox genes can be made to the role of a play dire
