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 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.

The SRY HMG box recognizes DNA by partial intercalation in the minor groove. It binds to the DNA consensus sequence 5'-[AT]AACAA[AT]-3'. 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-5 is the only member of group G Sox transcription factors. It is also called SOX-12, SOX-20, SOX-26, or SOX-27. SOX-5 is a crucial transcription factor involved in the regulation of embryonic development and in cell fate determination. It binds to the 5'-AACAAT-3' sequence.

first 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 first one.

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.

HMG-box domain; This short 71 residue domain is an HMG-box domain. HMG-box domains mediate re-modelling of chromatin-structure. Mammalian HMG-box proteins are of two types: those that are non-sequence-specific DNA-binding proteins with two HMG-box domains and a long highly acidic C-tail; and a diverse group of sequence-specific transcription factor-proteins with either a single HMG-box or up to six copies, and no acidic C-tail.

high mobility group (HMG)-box found in structure-specific recognition protein 1 (SSRP1) and similar proteins; SSRP1, also called FACT complex subunit SSRP1, chromatin-specific transcription elongation factor 80 kDa subunit, facilitates chromatin transcription complex 80 kDa subunit (FACT 80 kDa subunit or FACTp80), facilitates chromatin transcription complex subunit SSRP1, recombination signal sequence recognition protein 1, or T160, is a factor that facilitates transcript elongation through nucleosomes. It 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.

high mobility group (HMG)-box found in SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily E member 1 (SMARCE1) and similar proteins; SMARCE1, also called BRG1-associated factor 57 (BAF57), is a ubiquitously expressed protein involved in transcriptional activation and repression of select genes by chromatin remodeling. It is a component of SWI/SNF chromatin remodeling complexes that carry out key enzymatic activities, changing chromatin structure by altering DNA-histone contacts within a nucleosome in an ATP-dependent manner. SMARCE1 has a single HMG domain that displays non-specific DNA-binding characteristics. It also contains a kinesin-like coiled-coil (KLCC) domain.

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.
