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 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'.

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 Forkhead box protein J1 (FOXJ1) and similar proteins; FOXJ1, also called Forkhead-related protein FKHL13 or hepatocyte nuclear factor 3 Forkhead homolog 4 (HFH-4), acts as a transcription factor specifically required for the formation of motile cilia. 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 activates the transcription of a variety of ciliary proteins in the developing brain and lung. The FH domain is a winged helix DNA-binding domain.

Forkhead (FH) domain found in the Forkhead box protein O (FOXO) subfamily; The FOXO subfamily includes several winged helix transcription factors: FOXO1, FOXO3, FOXO4 and FOXO6. FOXO transcription factors are involved in the regulation of longevity phenomenon via insulin and insulin-like growth factor signaling. All FOXOs bind to the consensus sequence 5'-GTAAACAA-3', known as the DAF-16 family member-binding element, which includes the core sequence 5'-(A/C)AA(C/T)A-3' recognized by all FOX family members. FOXO1, also called Forkhead box protein O1A or Forkhead in rhabdomyosarcoma (FKHR), is a transcription factor that is the main target of insulin signaling and regulates metabolic homeostasis in response to oxidative stress. FOXO3, also called AF6q21 protein or Forkhead in rhabdomyosarcoma-like 1 (FKHRL1), is a transcriptional activator which triggers apoptosis in the absence of survival factors, including neuronal cell death upon oxidative stress. It recognizes and binds to the DNA sequence 5'-[AG]TAAA[TC]A-3'. FOXO4, also called Fork head domain transcription factor AFX1, is a transcription factor involved in the regulation of the insulin signaling pathway. It binds to insulin-response elements (IREs) and can activate transcription of IGFBP1. FOXO6 acts as a transcriptional activator that may play an important role on tumor invasion, metastasis, and prognosis. The FH domain is a winged helix DNA-binding domain.

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.

Forkhead (FH) domain found in Forkhead box protein N2 (FOXN2); FOXN2, also called human T-cell leukemia virus enhancer factor (HTLF), is a potential tumor suppressor that can facilitate replication fork reversal. It acts as a transcription factor that binds to the purine-rich region in human T-cell leukemia virus long terminal repeat (HTLV-I LTR). It may be a potential therapeutic and radiosensitization target for lung cancer. FOXN2 has also been found to be down-regulated in breast cancer, where it regulates migration, invasion, and epithelial-mesenchymal transition. 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'.
