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.

second high mobility group (HMG)-box found in the high mobility group protein B (HMGB) family; HMGB proteins are chromatin-associated nuclear proteins that act as architectural factors in nucleoprotein structures, which regulate DNA-dependent processes including transcription. In mammals, four family members are present: HMGB1, HMGB2, HMGB3 and HMGB4. They regulate the expression of a wide range of genes through architectural remodeling of the chromatin structure. HMGB1, also called high mobility group protein 1 (HMG-1), is a prototypical alarmin or damage-associated molecular pattern (DAMP) molecule when released from cells. It plays important roles in the regulation of a wide range of processes, including transcription, replication, DNA repair, and nucleosome formation, in the nucleus. It also plays multiple roles in regulating inflammation and responses to cell and tissue stress. HMGB2, also called high mobility group protein 2 (HMG-2), has been implicated in numerous cellular processes, including proliferation, differentiation, apoptosis, and tumor growth. It acts as a chromatin-associated nonhistone protein involved in transcriptional regulation and nucleic-acid-mediated innate immune responses in mammalian. It binds DNA to stabilize nucleosomes and promote transcription. HMGB3, also called high mobility group protein 2a (HMG-2a), or high mobility group protein 4 (HMG-4), is an X-linked member of HMGB family and functions as a universal sentinel for nucleic acid-mediated innate immune responses. HMGB3 has been implicated in the regulation of cellular proliferation and differentiation, as well as inflammatory response. HMGB4 is expressed by neuronal cells and affects the expression of genes involved in neural differentiation. It is a factor that regulates chromatin and expression of neuronal differentiation markers. The family also includes high mobility group protein B1 pseudogene 1 (HMGB1P1) and nuclear auto-antigen Sp-100. HMGB1P1, also called putative high mobility group protein B1-like 1 (HMGB1L1), or putative high mobility group protein 1-like 1 (HMG-1L1), is an HMG-box containing protein that binds preferentially single-stranded DNA and unwinds double-stranded DNA. Sp-100, also called nuclear dot-associated Sp100 protein, or speckled 100 kDa. It is a tumor suppressor that is a major constituent of the promyelocytic leukemia (PML) bodies, a subnuclear organelle involved in many physiological processes including cell growth, differentiation and apoptosis. Through the regulation of ETS1, Sp-100 may play a role in angiogenesis, controlling endothelial cell motility and invasion. It may also play roles in the regulation of telomeres lengthening, TP53-mediated transcription, FAS-mediated apoptosis, etc. In addition, the family includes Drosophila melanogaster high mobility group protein DSP1 (dDSP1) and similar proteins. dDSP1, also called protein dorsal switch 1, is a Drosophila HMG1 protein that binds preferentially single-stranded DNA and unwinds double-stranded DNA. It converts Dorsal and nuclear factor (NF)-kappa B from transcriptional activators to repressors. Members of the HMGB family contain two HMG-box domains. This model corresponds to the second one.

high mobility group (HMG)-box found in the TOX high mobility group box family; The TOX family includes four members: TOX, TOX2, TOX3 and TOX4. TOX, also called thymus high mobility group box protein TOX, is a transcriptional regulator with a major role in neural stem cell commitment and corticogenesis as well as in lymphoid cell development and lymphoid tissue organogenesis. It binds to GC-rich DNA sequences in the proximity of transcription start sites and may alter chromatin structure, modifying access of transcription factors to DNA. TOX2, also called granulosa cell HMG box protein 1 (GCX-1), is a putative transcriptional activator involved in the hypothalamic-pituitary-gonadal system. TOX3, also called CAG trinucleotide repeat-containing gene F9 protein (CAGF9), or trinucleotide repeat-containing gene 9 protein (TNRC9), is a transcriptional coactivator of the p300/CBP-mediated transcription complex. It activates transactivation through cAMP response element (CRE) sites. It protects against cell death by inducing anti-apoptotic and repressing pro-apoptotic transcripts. TOX4, also called epidermal Langerhans cell protein LCP1, is a component of the PTW/PP1 phosphatase complex, which plays a role in the control of chromatin structure and cell cycle progression during the transition from mitosis into interphase. All family members contain one HMG-box domain.

high mobility group (HMG)-box found in group A, group B and group G of SRY-related high-mobility group (HMG) box (Sox) transcription factors; This subfamily includes SoxA, SoxB, and SoxG proteins. SRY is the only member of group A SRY-related high-mobility group (HMG) box (Sox) transcription factors. SRY, also called testis-determining factor, is a transcriptional regulator that controls a genetic switch in male development. It promotes DNA bending and is also involved in pre-mRNA splicing. 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. SOX-15 can be a tumor suppressor in multiple cancer types.

high mobility group (HMG)-box found in the transcription factor 7 (TCF-7)-like family; The TCF7-like family includes TCF-7, TCF7-like 1 (TF7L1), lymphoid enhancer-binding factor 1 (LEF-1), and similar proteins. TCF-7, also called T-cell-specific transcription factor 1, or T-cell factor 1 (TCF-1), is a T lymphocyte-specific transcriptional activator involved in T-cell lymphocyte differentiation. It is necessary for the survival of CD4(+) CD8(+) immature thymocytes. It binds to the T-lymphocyte-specific enhancer element (5'-WWCAAAG-3') found in the promoter of the CD3E gene. TF7L1, also called HMG box transcription factor 3 (TCF-3), participates in the Wnt signaling pathway. It binds to DNA and acts as a repressor in the absence of CTNNB1, and as an activator in its presence. TF7L2, also called HMG box transcription factor 4, or T-cell-specific transcription factor 4, or T-cell factor 4, or TCF-4, participates in the Wnt signaling pathway and modulates MYC expression by binding to its promoter in a sequence-specific manner. It acts as a repressor in the absence of CTNNB1, and it activates transcription from promoters with several copies of the TCF motif 5'-CCTTTGATC-3' in the presence of CTNNB1. LEF-1, also called T cell-specific transcription factor 1-alpha (TCF1-alpha), is a transcription factor that binds DNA in a sequence-specific manner. It may participate in the Wnt signaling pathway. All family members contain one HMG-box domain.
