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).

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 involved in programming organogenesis and regulating epithelial-to-mesenchymal transition (EMT) and cell proliferation. FOXF2 dysregulation is critical for tumorigenesis of various tissue types. Its expression correlates with good prognosis in patients with early non-invasive stages of breast cancer, but with poor prognosis in advanced breast cancer. 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'.

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.

Forkhead (FH) domain found in Forkhead box protein P1 (FOXP1); FOXP1, also called Mac-1-regulated Forkhead (MFH), is a transcription factor that is widely expressed and has a broad range of functions. It has been shown to have a role in cardiac, lung, and lymphocyte development. Deregulation of FOXP1 is an important contributor to the pathogenesis of diffuse large B-cell lymphoma (DLBCL), suggesting it may function as an oncogene. Loss of FOXP1 expression in breast cancer is associated with a worse outcome, suggesting that FOXP1 may function as a tumor suppressor in some tissues. Haploinsufficiency of the FOXP1 gene leads to a neurodevelopmental disorder termed FOXP1 syndrome, characterized by developmental delay, intellectual disability, autism spectrum disorder, speech delay, and dysmorphic features. 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'.
