Zinc finger, C2H2 type; The C2H2 zinc finger is the classical zinc finger domain. The two conserved cysteines and histidines co-ordinate a zinc ion. The following pattern describes the zinc finger. #-X-C-X(1-5)-C-X3-#-X5-#-X2-H-X(3-6)-[H/C] Where X can be any amino acid, and numbers in brackets indicate the number of residues. The positions marked # are those that are important for the stable fold of the zinc finger. The final position can be either his or cys. The C2H2 zinc finger is composed of two short beta strands followed by an alpha helix. The amino terminal part of the helix binds the major groove in DNA binding zinc fingers. The accepted consensus binding sequence for Sp1 is usually defined by the asymmetric hexanucleotide core GGGCGG but this sequence does not include, among others, the GAG (=CTC) repeat that constitutes a high-affinity site for Sp1 binding to the wt1 promoter.

 37-120 1.81e-35

SCAN oligomerization domain; The SCAN domain (named after SRE-ZBP, CTfin51, AW-1 and Number 18 cDNA) is found in several vertebrate proteins that contain C2H2 zinc finger motifs, many of which may be transcription factors playing roles in cell survival and differentiation. This protein-interaction domain is able to mediate homo- and hetero-oligomerization of SCAN-containing proteins. Some SCAN-containing proteins, including those of lower vertebrates, do not contain zinc finger motifs. It has been noted that the SCAN domain resembles a domain-swapped version of the C-terminal domain of the HIV capsid protein. This domain model features elements common to the three general groups of SCAN domains (SCAN-A1, SCAN-A2, and SCAN-B). The SCAND1 protein is truncated at the C-terminus with respect to this model, the SCAND2 protein appears to have a truncated central helix.

KRAB box; The KRAB domain (or Kruppel-associated box) is present in about a third of zinc finger proteins containing C2H2 fingers. The KRAB domain is found to be involved in protein-protein interactions. The KRAB domain is generally encoded by two exons. The regions coded by the two exons are known as KRAB-A and KRAB-B. The A box plays an important role in repression by binding to corepressors, while the B box is thought to enhance this repression brought about by the A box. KRAB-containing proteins are thought to have critical functions in cell proliferation and differentiation, apoptosis and neoplastic transformation.

 221-249 5.43e-08

KRAB (Kruppel-associated box) domain -A box; The KRAB domain is a transcription repression module, found in a subgroup of the zinc finger proteins (ZFPs) of the C2H2 family, KRAB-ZFPs. KRAB-ZFPs comprise the largest group of transcriptional regulators in mammals, and are only found in tetrapods. These proteins have been shown to play important roles in cell differentiation and organ development, and in regulating viral replication and transcription. A KRAB domain may consist of an A-box, or of an A-box plus either a B-box, a divergent B-box (b), or a C-box. Only the A-box is included in this model. The A-box is needed for repression, the B- and C- boxes are not. KRAB-ZFPs have one or two KRAB domains at their amino-terminal end, and multiple C2H2 zinc finger motifs at their C-termini. Some KRAB-ZFPs also contain a SCAN domain which mediates homo- and hetero-oligomerization. The KRAB domain is a protein-protein interaction module which represses transcription through recruiting corepressors. A key mechanism appears to be the following: KRAB-AFPs tethered to DNA recruit, via their KRAB domain, the repressor KAP1 (KRAB-associated protein-1, also known as transcription intermediary factor 1 beta , KRAB-A interacting protein , and tripartite motif protein 28). The KAP1/ KRAB-AFP complex in turn recruits the heterochromatin protein 1 (HP1) family, and other chromatin modulating proteins, leading to transcriptional repression through heterochromatin formation.

 461-513 5.14e-04

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.

SCAN oligomerization domain; The SCAN domain (named after SRE-ZBP, CTfin51, AW-1 and Number 18 cDNA) is found in several vertebrate proteins that contain C2H2 zinc finger motifs, many of which may be transcription factors playing roles in cell survival and differentiation. This protein-interaction domain is able to mediate homo- and hetero-oligomerization of SCAN-containing proteins. Some SCAN-containing proteins, including those of lower vertebrates, do not contain zinc finger motifs. It has been noted that the SCAN domain resembles a domain-swapped version of the C-terminal domain of the HIV capsid protein. This domain model features elements common to the three general groups of SCAN domains (SCAN-A1, SCAN-A2, and SCAN-B). The SCAND1 protein is truncated at the C-terminus with respect to this model, the SCAND2 protein appears to have a truncated central helix.

KRAB box; The KRAB domain (or Kruppel-associated box) is present in about a third of zinc finger proteins containing C2H2 fingers. The KRAB domain is found to be involved in protein-protein interactions. The KRAB domain is generally encoded by two exons. The regions coded by the two exons are known as KRAB-A and KRAB-B. The A box plays an important role in repression by binding to corepressors, while the B box is thought to enhance this repression brought about by the A box. KRAB-containing proteins are thought to have critical functions in cell proliferation and differentiation, apoptosis and neoplastic transformation.

 221-249 5.43e-08

KRAB (Kruppel-associated box) domain -A box; The KRAB domain is a transcription repression module, found in a subgroup of the zinc finger proteins (ZFPs) of the C2H2 family, KRAB-ZFPs. KRAB-ZFPs comprise the largest group of transcriptional regulators in mammals, and are only found in tetrapods. These proteins have been shown to play important roles in cell differentiation and organ development, and in regulating viral replication and transcription. A KRAB domain may consist of an A-box, or of an A-box plus either a B-box, a divergent B-box (b), or a C-box. Only the A-box is included in this model. The A-box is needed for repression, the B- and C- boxes are not. KRAB-ZFPs have one or two KRAB domains at their amino-terminal end, and multiple C2H2 zinc finger motifs at their C-termini. Some KRAB-ZFPs also contain a SCAN domain which mediates homo- and hetero-oligomerization. The KRAB domain is a protein-protein interaction module which represses transcription through recruiting corepressors. A key mechanism appears to be the following: KRAB-AFPs tethered to DNA recruit, via their KRAB domain, the repressor KAP1 (KRAB-associated protein-1, also known as transcription intermediary factor 1 beta , KRAB-A interacting protein , and tripartite motif protein 28). The KAP1/ KRAB-AFP complex in turn recruits the heterochromatin protein 1 (HP1) family, and other chromatin modulating proteins, leading to transcriptional repression through heterochromatin formation.

 461-513 5.14e-04

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.

Zinc finger, C2H2 type; The C2H2 zinc finger is the classical zinc finger domain. The two conserved cysteines and histidines co-ordinate a zinc ion. The following pattern describes the zinc finger. #-X-C-X(1-5)-C-X3-#-X5-#-X2-H-X(3-6)-[H/C] Where X can be any amino acid, and numbers in brackets indicate the number of residues. The positions marked # are those that are important for the stable fold of the zinc finger. The final position can be either his or cys. The C2H2 zinc finger is composed of two short beta strands followed by an alpha helix. The amino terminal part of the helix binds the major groove in DNA binding zinc fingers. The accepted consensus binding sequence for Sp1 is usually defined by the asymmetric hexanucleotide core GGGCGG but this sequence does not include, among others, the GAG (=CTC) repeat that constitutes a high-affinity site for Sp1 binding to the wt1 promoter.
