WebHox genes have revealed many clues about the evolution of the animal family tree. The similarities among Hox genes, especially in the shared homeobox sequence, suggest that they all arose from a single ancestral gene that was duplicated multiple times. After each duplication event, the genes gradually changed, taking on slightly different jobs. Web1 okt. 2004 · Human Cdx2 is a member of the caudal-related homeobox gene family that activates an intestinal-specific gene transcription, which regulates normal intestinal development and differentiation and plays an important role in triggering cells towards the phenotype of differentiated enterocytes as well as in the maintenance of the phenotype.
