<i>AmphiFoxE4</i>, an amphioxus winged helix/forkhead gene encoding a protein closely related to vertebrate thyroid transcription factor‐2: expression during pharyngeal development

Abstract excerpt

The full-length sequence and developmental expression of amphioxus AmphiFoxE4 are described. Transcripts of the gene are first detected in the pharyngeal endoderm, where the club-shaped gland is forming and subsequently in the definitive gland itself. AmphiFoxE4 is closely related to vertebrate genes encoding the thyroid-specific transcription factor-2 (TTF2), which plays an early developmental role in the...
