Expression pattern of the winged helix factor XFD-11 during Xenopus embryogenesis.
We have identified a cDNA encoding a novel Xenopus winged helix transcription factor termed as XFD-11 (Xenopus fork head domain). The DNA binding domain is most closely related to those of human or murine FREAC-3 (FKHL7/MF-1/FKH-1) proteins. The XFD-11 gene is activated at late blastula/early gastrula and transcription proceeds throughout embryogenesis. Early expression is found in ventral and lateral but not in dorsal mesoderm. At neurula stages, transcripts are found in posterior mesoderm except for the dorsal midline, and the gene is also transcribed at the lateral border of the neural plate and within anterior neuroectoderm. At later stages of development, transcripts are detected within the pronephros, the heart, within neural crest cells surrounding the eye, in the mandibular, hyoid and branchial arches, and within the tail.
