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'.

Forkhead (FH) domain found in Forkhead box proteins FOXD1, FOXD2 and similar proteins; FOXD1, also called Forkhead-related protein FKHL8, or Forkhead-related transcription factor 4 (FREAC-4), is involved in transcriptional activation of Placental Growth Factor (PGF) and the complement component (C3) genes. It plays an important role in early embryonic development and organogenesis, and functions as an oncogene in several cancers. FOXD2, also called Forkhead-related protein FKHL17, or Forkhead-related transcription factor 9 (FREAC-9), is a probable transcription factor involved in embryogenesis and somatogenesis. It has been found that long noncoding RNA FOXD2 adjacent opposite strand RNA1 (lncRNA FOXD2-AS1) expression is upregulated in various human malignancies, including gastric, lung, bladder, colorectal, nasopharyngeal, esophageal, hepatocellular, thyroid and skin cancer. It is a promising candidate as a new biomarker and therapeutic target for cancer diagnosis/prognostication due to high tissue specificity and elevated efficiency.

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'.

Forkhead (FH) domain found in the Forkhead box protein D (FOXD) subfamily; The FOXD subfamily includes four winged helix transcription factors, FOXD1-4. FOXD1, also called Forkhead-related protein FKHL8 or Forkhead-related transcription factor 4 (FREAC-4), is involved in transcriptional activation of Placental Growth Factor (PGF) and the complement component (C3) genes. It plays an important role in early embryonic development and organogenesis, and functions as an oncogene in several cancers. FOXD2, also called Forkhead-related protein FKHL17 or Forkhead-related transcription factor 9 (FREAC-9), is a probable transcription factor involved in embryogenesis and somatogenesis. FOXD3, also called HNF3/FH transcription factor genesis, acts as a transcriptional repressor that binds to the consensus sequence 5'-A[AT]T[AG]TTTGTTT-3'. It also acts as a transcriptional activator. It promotes development of neural crest cells from neural tube progenitors and restricts neural progenitor cells to the neural crest lineage while suppressing interneuron differentiation. FOXD3 is required for maintenance of pluripotent cells in the pre-implantation and peri-implantation stages of embryogenesis. FOXD4, also called Forkhead-related protein FKHL9 or Forkhead-related transcription factor 5 (FREAC-5), is essential for establishing neural cell fate and for neuronal differentiation. The family also includes Forkhead box protein D4-like proteins, FOXD4L1-6. 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 K (FOXK) subfamily; The FOXK subfamily includes two winged helix transcription factors, FOXK1 and FOXK2. FOXK1, also called myocyte nuclear factor (MNF), acts as a transcriptional regulator that binds to the upstream enhancer region (CCAC box) of myoglobin genes. It positively regulates Wnt/beta-catenin signaling by translocating dishevelled (DVL) proteins into the nucleus. It also reduces virus replication, probably by binding the interferon stimulated response element (ISRE) to promote antiviral gene expression. In addition, FOXK1 plays important roles in multiple human cancers. FOXK2, also called cellular transcription factor ILF-1 or interleukin enhancer-binding factor 1, is a transcriptional regulator that recognizes the core sequence 5'-TAAACA-3'. It binds to NFAT-like motifs (purine-rich) in the IL2 promoter. It also binds to the HIV-1 long terminal repeat. FOXK2 may be involved in both, positive and negative regulation of important viral and cellular promoter elements. In addition, FOXK2 plays a critical role in suppressing tumorigenesis. 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'.
