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 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'.
