Transcription Factor Domain

TF Family: Fork_head
Domain: Fork_head domain
PFAM: PF00250
TF Group: Helix-turn-helix
Description: The fork head domain is a conserved DNA-binding domain (also known as a winged helix) of about 100 amino-acid residues. Drosophila melanogaster fork head protein is a transcription factor that promotes terminal rather than segmental development, contains neither homeodomains nor zinc-fingers characteristic of other transcription factors [1]. Instead, it contains a distinct type of DNA-binding region, containing around 100 amino acids, which has since been identified in a number of transcription factors (including D. melanogaster FD1-5, mammalian HNF-3, human HTLF, Saccharomyces cerevisiae HCM1, etc.). This is referred to as the fork head domain but is also known as a 'winged helix' [1, 2, 3]. The fork head domain binds B-DNA as a monomer [2], but shows no similarity to previously identified DNA-binding motifs. Although the domain is found in several different transcription factors, a common function is their involvement in early developmental decisions of cell fates during embryogenesis [3].
