Ataxin-1 and HBP1 module (AXH); AXH is a protein-protein and RNA binding motif found in Ataxin-1 (ATX1). ATX1 is responsible for the autosomal-dominant neurodegenerative disorder Spinocerebellar ataxia type-1 (SCA1) in humans. The AXH module has also been identified in the apparently unrelated transcription factor HBP1 which is thought to be involved in the architectural regulation of chromatin and in specific gene expression.

high mobility group (HMG)-box found in sex-determining region Y (SRY)-box (SOX) family transcription factors; The SOX gene family of transcription factors are characterized by the evolutionarily conserved SRY-type HMG box, which is a DNA binding domain that binds the minor groove of DNA on a common consensus site, (A/T)(A/T)CAA(A/T)G but with different levels of efficiency. Members include SRY and its homologs identified in mammals that can be subdivided into 8 groups (A, B1, B2, C, D, E, F, G, H). They are involved in embryonic development, regulating processes such as cell differentiation, maintenance of stemness, sex determination, and development of the central nervous, haematopoietic and other organ systems. The SOX gene family has a crucial role in carcinogenesis and cancer progression.

These proteins contain a single HMG box, and bind the minor groove of DNA in a highly sequence-specific manner. ROX1, also called heme-dependent repression factor, or hypoxic function repressor, is a transcription factor that represses the expression of HEM13, COX5B, ANB1, CYC7 or AAC3. It binds to the DNA sequence 5'-RRRTAACAAGAG-3'. mat-Mc belongs to the mating type protein family, which contains sequence specific DNA-binding proteins that act as master switches in yeast differentiation by controlling gene expression in a cell type-specific fashion. mat-Mc is a positive regulator of MFM genes and is required for conjugation and efficient meiosis. Its HMG box recognizes the DNA sequence 5'-AACAAAG-3'. Ste11 is a key transcription factor for sexual development. It activates the transcription of the matp, matm, mei2, mfm, ste6 and rgs1 genes. It binds specifically to a DNA fragment carrying a 10-base motif 5'-TTCTTTGTTY-3'. FPR1 controls fertilization, probably by determining the mating type. SMR2 is a transcription factor that is required for post-fertilization events. It is required for the developmental events that occur in the female organ after fertilization. RFG1 is a transcription regulator that functions in both the positive and negative regulation of filamentous growth, depending upon environmental conditions.

high mobility group (HMG)-box domain superfamily; The High Mobility Group (HMG)-box is found in a variety of eukaryotic chromosomal proteins and transcription factors. HMGs bind to the minor groove of DNA and have been classified by DNA binding preferences. Two phylogenetically distinct groups of Class I proteins bind DNA in a sequence specific fashion and contain a single HMG box. One group (SOX-TCF) includes transcription factors, TCF-1, -3, -4, and also SRY and LEF-1, which bind four-way DNA junctions and duplex DNA targets. The second group (MATA) includes fungal mating type gene products MC, MATA1 and Ste11. Class II and III proteins (HMGB-UBF) bind DNA in a non-sequence specific fashion and contain two or more tandem HMG boxes. Class II members include non-histone chromosomal proteins, HMG1 and HMG2, which bind to bent or distorted DNA such as four-way DNA junctions, synthetic DNA cruciforms, kinked cisplatin-modified DNA, DNA bulges, cross-overs in supercoiled DNA, and can cause looping of linear DNA. Class III members include nucleolar and mitochondrial transcription factors, UBF and mtTF1, which bind four-way DNA junctions.

high mobility group (HMG)-box found in group B SRY-related high-mobility group (HMG) box (Sox) transcription factors; SoxB transcription factors play critical roles in the regulation of neurogenesis. They can be divided into two main subgroups, SoxB1 (Sox-1/Sox-2/Sox-3) and SoxB2 (SOX-14/SOX-21). SoxB1 proteins suppress neurogenesis by maintaining neural cells in an undifferentiated state. SoxB2 proteins may have the opposite activity and promote neuronal differentiation. SOX-1 is involved in the regulation of embryonic development and cell fate determination. It also acts as a tumor suppressor that plays an anti-tumorigenicity role in different cells and its expression is inhibited in a variety of cancers. SOX-2 plays an important role in various phases of embryonic development, including cell fate and differentiation. Its overexpression and gene amplification may be associated with tumor aggression and metastasis in various cancer types, including breast, prostate, lung, ovarian and colon cancer. SOX-3 is required during the formation of the hypothalamic-pituitary axis. It plays a role in both normal neural development and carcinogenesis. SOX-14, also called SOX-28, acts as a negative regulator of transcription. It is mainly involved in the regulation of neural development. It can also promote proliferation and invasion capacity of cervical cancer cells by activating the Wnt/beta-catenin pathway. SOX-21, also called SOX-A, or SOX-25, promotes the progression of vertebrate neurogenesis.

NHP6A and NHP6B seem to be functionally redundant. They are DNA-binding proteins that induce severe bending of DNA and are required for DNA-binding by the FACT complex, a general chromatin factor that acts to reorganize nucleosomes. They augment the fidelity of transcription by RNA polymerase III independently of any role in the FACT complex. They may also play essential roles in transcriptional initiation fidelity of some but not all tRNA genes.

high mobility group (HMG)-box found in Arabidopsis thaliana FACT complex subunit SSRP1 and similar proteins; SSRP1, also called facilitates chromatin transcription complex subunit SSRP1, high mobility group B protein 8, nucleosome/chromatin assembly factor group D 08 (or D 8), protein NUCLEAR FUSION DEFECTIVE 8, or recombination signal sequence recognition protein 1, is a component of the FACT complex, a general chromatin factor that acts to reorganize nucleosomes. The FACT complex is involved in multiple processes that require DNA as a template such as mRNA elongation, DNA replication, and DNA repair. SSRP1 may bind specifically to double-stranded DNA. It is required for karyogamy during female gametophyte development, when the two polar nuclei fuse to form the diploid central cell nucleus. SSRP1 contains only one HMG-box domain.

high mobility group (HMG)-box found in sex determining region Y (SRY)-box 4 (SOX4) and similar proteins; SOX-4 is a transcriptional activator that promotes neuronal differentiation both in the adult and embryonic neural progenitors. It binds with high affinity to the T-cell enhancer motif 5'-AACAAAG-3' motif. SOX-4 is abnormally expressed in various cancers. SOX-4 belongs to group C SRY-related high-mobility group (HMG) box (Sox) transcription factors.

first high mobility group (HMG)-box found in Saccharomyces cerevisiae intrastrand cross-link recognition protein (Ixr1) and similar proteins; Ixr1, also called structure-specific recognition protein (SSRP), is a homolog of the yeast mitochondrial regulator ABF2. It binds to platinated DNA and confers sensitivity to the anticancer drug cisplatin. Ixr1 contains two HMG-box domains. This model corresponds to the first one.

second high mobility group (HMG)-box found in Arabidopsis thaliana high mobility group B protein 6 (HMGB6) and similar proteins; HMGB6, also called nucleosome/chromatin assembly factor group D 06 (or D 6), WRKY transcription factor 53 (WRKY53), or WRKY DNA-binding protein 53, is a master regulator of age-induced leaf senescence. It acts in a complex transcription factor signaling network regulating senescence specific gene expression; hydrogen peroxide might be involved in signal transduction. The subfamily also includes Arabidopsis thaliana HMGB13 (also known as nucleosome/chromatin assembly factor group D 13). Both HMGB6 and HMGB13 contain three HMG-box domains. This model corresponds to the second one.

high mobility group (HMG)-box found in protein polybromo-1 (PB1) and similar proteins; PB1, also called BRG1-associated factor 180 (BAF180), or polybromo-1D, is a subunit of the PBAF (polybromo/Brg1-associated factor) chromatin-remodeling complex required for kinetochore localization during mitosis and the transcription of estrogen-responsive genes. It is involved in transcriptional activation and repression of select genes by chromatin remodeling. It acts as a negative regulator of cell proliferation.
