Forkhead (FH) domain found in the Forkhead box protein G (FOXG) subfamily; The FOXG subfamily includes a winged helix transcription factor FOXG1, which is also called brain factor 1 (BF-1), brain factor 2 (BF-2), Forkhead box protein G1A, Forkhead box protein G1B, Forkhead box protein G1C, Forkhead-related protein FKHL1, Forkhead-related protein FKHL2, or Forkhead-related protein FKHL3. FOXG1 acts as a transcription repression factor which plays an important role in the establishment of the regional subdivision of the developing brain and in the development of the telencephalon. It is repetitively used in the sequential events of telencephalic development to control multi-steps of brain circuit formation ranging from cell cycle control to neuronal differentiation in a clade- and species-specific manner. Individuals with mutations in FOXG1 harbor "FOXG1-related encephalopathy", characterized by two clinical phenotypes/syndromes including microcephaly, developmental delay, severe cognitive disabilities, early-onset dyskinesia and hyperkinetic movements, stereotypies, epilepsy, and cerebral malformation for those with deletions or intragenic mutations of FOXG1. The FH domain is a winged helix DNA-binding domain. FOX transcription factors recognize the core sequence 5'-(A/C)AA(C/T)A-3'.

It is required for induction of the goosecoid (GSC) promoter by TGF-beta or activin signaling. FOXH1 forms a transcriptionally active complex containing FOXH1/SMAD2/SMAD4 on a site on the GSC promoter called TARE (TGF-beta/activin response element). The FH domain is a winged helix DNA-binding domain. FOX transcription factors recognize the core sequence 5'-(A/C)AA(C/T)A-3'.

Forkhead (FH) domain found in the Forkhead box protein A (FOXA) subfamily; The FOXA subfamily includes three winged helix transcription factors, FOXA1 (also called hepatocyte nuclear factor 3-alpha or transcription factor 3A), FOXA2 (also called hepatocyte nuclear factor 3-beta or transcription factor 3B), and FOXA3 (also called hepatocyte nuclear factor 3-gamma or transcription factor 3G). FOXA1 is essential for epithelial lineage differentiation and has been found to be upregulated in numerous cancers. FOXA2 controls cell differentiation. It is a key transcriptional regulator that maintains airway mucus homeostasis and may also have an important role in bone metabolism. FOXA3 acts as an essential transcriptional regulator engaged in adipogenesis and energy metabolism. This subfamily also includes Xenopus tropicalis FOXA4, Drosophila melanogaster protein fork head (dFKH), and similar proteins. FOXA4 is only present in amphibians, where it is required for the correct regionalization and maintenance of the central nervous system. dFKH promotes terminal as opposed to segmental development. In the absence of dFKH, this developmental switch does not occur. The FH domain is a winged helix DNA-binding domain. FOX transcription factors recognize the core sequence 5'-(A/C)AA(C/T)A-3'.
