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.

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.

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 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.

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.
