Homothorax (HTH or HTX) is a transcriptional co-factor to
Hox genes that is closely connected with
extradenticle.
It may play a role in the identification of segments during
panarthropod development.
The gene acts in a similar way across the panarthropod phyla, although its expression pattern is reversed in the millipedes, centipedes and crustaceans.
