Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in cranial skeletal system development. Acts upstream of or within several processes, including animal organ development; roof of mouth development; and thyroid hormone generation. Predicted to be located in nucleus. Is expressed in several structures, including alimentary system; brain; branchial pouch endoderm; head surface ectoderm; and outflow tract. Used to study Bamforth-Lazarus syndrome and congenital hypothyroidism. Human ortholog(s) of this gene implicated in Bamforth-Lazarus syndrome and thyroid gland papillary carcinoma. Orthologous to human FOXE1 (forkhead box E1). [provided by Alliance of Genome Resources, Apr 2022]
