forkhead associated (FHA) domain found in forkhead box protein K1 (FOXK1) and similar proteins; FOXK1, also called myocyte nuclear factor (MNF), acts as a transcriptional regulator that binds to the upstream enhancer region (CCAC box) of the myoglobin gene. It positively regulates Wnt/beta-catenin signaling by translocating DVL 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. The FHA domain is a small phosphopeptide recognition module.

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'.

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'.

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.

Forkhead (FH) domain found in Forkhead box protein N4 (FOXN4); FOXN4 acts as a transcription factor essential for neural and some non-neural tissue development, such as retina and lung, respectively. During development of the central nervous system, FOXN4 is required in specifying the amacrine and horizontal cell fates from multipotent retinal progenitors, while suppressing alternative photoreceptor cell fates. In non-neural tissues, it plays an essential role in specifying the atrioventricular canal and is indirectly required for patterning the distal airway during lung development. 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 O3 (FOXO3); 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'. The FH domain is a winged helix DNA-binding domain. 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.

forkhead associated (FHA) domain found in Saccharomyces cerevisiae fork head protein homolog 1 (FKH1), 2 (FKH2) and similar proteins; This family includes FKH1 and FKH2, as well as pre-rRNA-processing protein FHL1. FKH1 and FKH2 are forkhead transcription factors that regulate the expression of the CLB2 cluster of genes during the G2/M phase of the mitotic cell cycle. The CLB2 cluster of genes includes mitotic regulators such as CLB1, CLB2, CDC5 and CDC20, as well as SWI5 and ACE2. FKH1 and FKH2 are involved in HMRa silencing. They associate with the coding regions of active genes and influence, in opposing ways, transcriptional elongation and termination, and coordinate early transcription elongation and pre-mRNA processing. Both FKH1 and FKH2 play a role as regulators of lifespan in collaboration with the anaphase-promoting complex (APC), likely through combined regulation of stress response, genomic stability, and cell cycle regulation. They also function in controlling yeast cell morphology by preventing pseudohyphal growth and act as rate-limiting replication origin activators via their interaction with the origin recognition complex (ORC). FHL1 is a forkhead protein that controls the pre-rRNA processing machinery in conjunction with IFH1. It might act as a transcriptional regulator of genes specifically involved in that process. IFH1 convert FHL1 from a repressor to an activator. This family also includes AtFHA1 and AtFHA2, which may play a role in the control of plant organ development. AtFHA2 is specifically involved in the regulation of stamen development. The FHA domain is a small phosphopeptide recognition module.

forkhead associated (FHA) domain found in microspherule protein 1 (MCRS1) and similar proteins; MCRS1, also called 58 kDa microspherule protein (MSP58), cell cycle-regulated factor p78, or INO80 complex subunit J, is a nuclear RNA-binding protein that interacts with fragile X mental retardation protein in polyribosomal ribonucleoparticles (mRNPs) from neurons. It is a cell-cycle-dependent protein that acts as an inhibitor of TERT telomerase activity. It associates with LPTS/PinX1 and reduces the telomere length. It modulates the transcription repressor activity of DAXX by recruiting it to the nucleolus. As part of the NSL complex, MCRS1 may be involved in acetylation of nucleosomal histone H4 on several lysine residues. MCRS1 is also a putative regulatory component of the chromatin remodeling INO80 complex, which is involved in transcriptional regulation, DNA replication, and probably DNA repair. MCRS1 contains an FHA domain at its C-terminus. The FHA domain is a small phosphopeptide recognition module.
