N-terminal domain of transcription factor Specificity Proteins (SP) 1-4; Specificity Proteins (SPs) are transcription factors that are involved in many cellular processes, including cell differentiation, cell growth, apoptosis, immune responses, response to DNA damage, and chromatin remodeling. There are many SPs in vertebrates (9 SPs in humans and mice, 7 SPs in chicken, and 11 SPs in teleost fish), but arthropods only have 3 SPs. SPs belong to a family of proteins, called the SP/Kruppel or Krueppel-like Factor (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. SP factors preferentially bind GC boxes, while KLFs bind CACCC boxes. Another characteristic hallmark of SP factors is the presence of the Buttonhead (BTD) box CXCPXC, just N-terminal to the zinc fingers. The function of the BTD box is unknown, but it is thought to play an important physiological role. Another feature of most SP factors is the presence of a conserved amino acid stretch, the so-called SP box, located close to the N-terminus. SP factors may be separated into three groups based on their domain architecture and the similarity of their N-terminal transactivation domains: SP1-4, SP5, and SP6-9. The transactivation domains between the three groups are not homologous to one another. SP1-4 have similar N-terminal transactivation domains characterized by glutamine-rich regions, which, in most cases, have adjacent serine/threonine-rich regions. This model represents the N-terminal domain of SP1-4.

N-terminal domain of transcription factor Specificity Protein (SP) 2; Specificity Proteins (SPs) are transcription factors that are involved in many cellular processes, including cell differentiation, cell growth, apoptosis, immune responses, response to DNA damage, and chromatin remodeling. SP2 contains the least conserved DNA-binding domain within the SP subfamily of proteins, and its DNA sequence specificity differs from the other SP proteins. It localizes primarily within subnuclear foci associated with the nuclear matrix, and can activate, or in some cases, repress expression from different promoters. The transcription factor SP2 serves as a paradigm for indirect genomic binding. It does not require its DNA-binding domain for genomic DNA binding and occupies target promoters independently of whether they contain a cognate DNA-binding motif.

N-terminal domain of Oryza sativa transcription factor SUPPRESSOR OF FRI 4 (OsSUF4), Arabidopsis thaliana SUF4 (AtSUF4), and similar proteins; Oryza sativa SUPPRESSOR OF FRI 4 (OsSUF4) is a C2H2-type zinc finger transcription factor which interacts with the major H3K36 methyltransferase SDG725 to promote H3K36me3 (tri-methylation at H3K9) establishment. The transcription factor OsSUF4 recognizes a specific 7-bp DNA element (5'-CGGAAAT-3'), which is contained in the promoter regions of many genes throughout the rice genome. Through interaction with OsSUF4, SDG725 is recruited to the promoters of key florigen genes, RICE FLOWERING LOCUS T1 (RFT1) and Heading date 3a (Hd3a), for H3K36 deposition to promote gene activation and rice plant flowering. OsSUF4 target genes include a number of genes involved in many biological processes. Flowering plant Arabidopsis SUF4 binds to a 15bp DNA element (5'-CCAAATTTTAAGTTT-3') within the promoter of the floral repressor gene FLOWERING LOCUS C (FLC) and recruits the FRI-C transcription activator complex to the FLC promoter. Although the DNA-binding element and target genes of AtSUF4 are different from those of OsSUF4, AtSUF4 is known to interact with the Arabidopsis H3K36 methyltransferase SDG8 (also known as ASHH2/EFS/SET8), and the methylation deposition mechanism mediated by the SUF4 transcription factor and H3K36 methyltransferase may be conserved in Arabidopsis and rice. Proteins in this family have two conserved C2H2-type zinc finger motifs at the N-terminus (included in this model), and a large proline-rich domain at the C-terminus; for OsSUF4, it has been shown that the N-terminal zinc-finger domain is responsible for DNA binding, and that the C-terminal domain interacts with SDG725.

N-terminal domain of transcription factor Specificity Protein (SP) 5; Specificity Proteins (SPs) are transcription factors that are involved in many cellular processes, including cell differentiation, cell growth, apoptosis, immune responses, response to DNA damage, and chromatin remodeling. There are many SPs in vertebrates (9 SPs in humans and mice, 7 SPs in the chicken, and 11 SPs in teleost fish), but arthropods only have 3 SPs. All of them contain clade SP5, which plays a potential role in human cancers and was found in several human tumors including hepatocellular carcinoma, gastric cancer, and colon cancer. Leukemia inhibitor factor/Stat3 and Wnt/beta-catenin signaling pathways converge on SP5 to promote mouse embryonic stem cell self-renewal. SP5 belongs to a family of proteins, called the SP/Kruppel or Krueppel-like Factor (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. SP factors preferentially bind GC boxes, while KLFs bind CACCC boxes. Another characteristic hallmark of SP factors is the presence of the Buttonhead (BTD) box CXCPXC, just N-terminal to the zinc fingers. The function of the BTD box is unknown, but it is thought to play an important physiological role. Another feature of most SP factors is the presence of a conserved amino acid stretch, the so-called SP box, located close to the N-terminus. SP factors may be separated into three groups based on their domain architecture and the similarity of their N-terminal transactivation domains: SP1-4, SP5, and SP6-9. The transactivation domains between the three groups are not homologous to one another. This model represents the N-terminal domain of SP5.
