N-terminal domain of Kruppel-like factor (KLF) 1, KLF2, KLF4, and similar proteins; Kruppel/Krueppel-like transcription factors (KLFs) belong to a family of proteins called the Specificity Protein (SP)/KLF family, characterized by a C-terminal DNA-binding domain of 81 amino acids consisting of three Kruppel-like C2H2 zinc fingers. These factors bind to a loose consensus motif, namely NNRCRCCYY (where N is any nucleotide; R is A/G, and Y is C/T), such as the recurring motifs in GC and GT boxes (5'-GGGGCGGGG-3' and 5-GGTGTGGGG-3') that are present in promoters and more distal regulatory elements of mammalian genes. Members of the KLF family can act as activators or repressors of transcription depending on cell and promoter context. KLFs regulate various cellular functions, such as proliferation, differentiation, and apoptosis, as well as the development and homeostasis of several types of tissue. In addition to the C-terminal DNA-binding domain, each KLF also has a unique N-terminal activation/repression domain that confers specifity and allows it to bind specifically to a certain partner, leading to distinct activities in vivo. This model represents the related N-terminal domains of KLF1, KLF2, KLF4, and similar proteins.

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 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'.

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. 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'.

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.

N-terminal domain of Kruppel-like factors with similarity to the N-terminal domains of Kruppel-like factor (KLF)1, KLF2, and KLF4; Kruppel/Krueppel-like transcription factors (KLFs) belong to a family of proteins called the Specificity Protein (SP)/KLF family, characterized by a C-terminal DNA-binding domain of 81 amino acids consisting of three Kruppel-like C2H2 zinc fingers. These factors bind to a loose consensus motif, namely NNRCRCCYY (where N is any nucleotide; R is A/G, and Y is C/T), such as the recurring motifs in GC and GT boxes (5'-GGGGCGGGG-3' and 5-GGTGTGGGG-3') that are present in promoters and more distal regulatory elements of mammalian genes. Members of the KLF family can act as activators or repressors of transcription depending on cell and promoter context. KLFs regulate various cellular functions, such as proliferation, differentiation, and apoptosis, as well as the development and homeostasis of several types of tissue. In addition to the C-terminal DNA-binding domain, each KLF also has a unique N-terminal activation/repression domain that confers specifity and allows it to bind specifically to a certain partner, leading to distinct activities in vivo. This model represents the N-terminal domains of an unknown subfamily of KLFs, predominantly found in fish, related to the N-terminal domains of KLF1, KLF2, and KLF4.
