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.

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.

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.
