Abstract Background The Fox gene family is a large family of transcription factors that arose
early in organismal evolution dating back to at least the common ancestor of metazoans and
fungi. They are key components of many gene regulatory networks essential for embryonic
development. Although much is known about the role of Fox genes during vertebrate
development, comprehensive comparative studies outside vertebrates are sparse. We have
characterized the Fox transcription factor gene family from the genome of the enteropneust …
