The large family encoding POU transcription factors has been described in several species. In particular, class III POU genes regulate critical steps of vertebrate and invertebrate neurogenesis. A novel amphioxus class III POU gene, AinphiBrn1/2/4, has been isolated and its spatio-temporal expression has been reported. AmphiBrn1/2/4 is first expressed in the dorsal epiblast, then throughout the neural plate except for a gap at level of the anterior region of the cerebral vesicle. Transcripts are also detected in the primordium of gill slits, pharynx and left Hatschek's diverticulum.

Abstract
The large family encoding POU transcription factors has been described in several species. In particular, class III POU genes regulate critical steps of vertebrate and invertebrate neurogenesis. A novel amphioxus class III POU gene, AinphiBrn1/2/4, has been isolated and its spatio-temporal expression has been reported. AmphiBrn1/2/4 is first expressed in the dorsal epiblast, then throughout the neural plate except for a gap at level of the anterior region of the cerebral vesicle. Transcripts are also detected in the primordium of gill slits, pharynx and left Hatschek's diverticulum.
