Forkhead (FH) domain found in Forkhead box protein P3 (FOXP3) and similar proteins; FOXP3, also called Scurfin, is a transcriptional regulator which is crucial for the development and inhibitory function of regulatory T-cells (Treg), which are required for maintaining self-tolerance. It may also have intrinsic regulatory function in conventional T (Tconv) cells. A deletion of the Forkhead domain arising from a frame-shift mutation in mouse FOXP3 is linked to the autoimmune disorder scurfy, and a similar congenital disease in humans is known as IPEX (immune dysregulation, polyendocrinopathy, enteropathy, X-linked syndrome). 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 P (FOXP) subfamily; The FOXP subfamily includes four winged helix transcription factors, FOXP1-4. They are involved in the development of the central nervous system. Mutations in FOXP1, also called Mac-1-regulated Forkhead (MFH), leads to developmental delay, intellectual disability, autism spectrum disorder, speech delay, and dysmorphic features. FOXP2, also called CAG repeat protein 44 or Trinucleotide repeat-containing gene 10 protein, is a transcriptional repressor that may play a role in the specification and differentiation of lung epithelium. It may also play a role in developing neural, gastrointestinal and cardiovascular tissues. FOXP3, also called Scurfin, is a transcriptional regulator which is crucial for the development and inhibitory function of regulatory T-cells (Treg). FOXP4, also called Forkhead-related protein-like A, is a transcriptional repressor that represses lung-specific expression. It is necessary for normal T cell cytokine recall responses to antigen following pathogenic infection. 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 Forkhead box (FOX) family of transcription factors and similar proteins; The FOX family comprises diverse tissue- and cell type-specific transcription factors with an evolutionary conserved "Forkhead (FH)" or "winged helix" DNA-binding domain. FH is named for the Drosophila fork head protein, a transcription factor which promotes terminal rather than segmental development. The structure of the FH domain contains 2 flexible loops or "wings" in the C-terminal region, hence the term winged helix. FOX transcription factors recognize the core sequence 5'-(A/C)AA(C/T)A-3'. They participate in a variety of cellular processes, such as cell cycle progression, proliferation, differentiation, migration, metabolism, and DNA damage response. Their expression can be regulated by multiple factors, and they can act as co-activators and/or transcriptional repressors. Fifty FOX-encoding genes in humans have been categorized into 19 subfamilies based on protein sequence homology (FOXA to FOXS).

It acts by activating transcription of genes that mediate assembly of motile cilia, such as CFAP157. FOXJ1 binds the DNA consensus sequences 5'-HWDTGTTTGTTTA-3' or 5'-KTTTGTTGTTKTW-3' (where H is not G, W is A or T, D is not C, and K is G or T).

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.
