Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in several processes, including circulatory system development; digestive tract development; and regulation of transcription, DNA-templated. Predicted to act upstream of or within several processes, including animal organ development; chordate embryonic development; and regulation of transcription by RNA polymerase II. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in persistent fetal circulation syndrome. Orthologous to human FOXF1 (forkhead box F1).
