Protein Domain : IPR001766

Name  Transcription factor, fork head Short Name  TF_fork_head
Type  Domain Description  The fork head protein of Drosophila melanogaster, a transcription factor that promotes terminal rather than segmental development, contains neither homeodomains nor zinc-fingers characteristic of other transcription factors []. 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 cerevisiaeHCM1, etc.). This is referred to as the fork head domain but is also known as a 'winged helix' [, , ].The fork head domain binds B-DNA as a monomer [], 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 [].
