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 Saccharomyces cerevisiae non-histone chromosomal proteins NHP6A, NHP6B and similar proteins; This subfamily includes Saccharomyces cerevisiae high-mobility-group proteins NHP6A and its closely related paralog NHP6B. 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.

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.

first 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 cells. 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 the HMGB family that 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 responses. 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. This 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, is a tumor suppressor that is a major constituent of 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 telomere 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, binds preferentially to 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 first one.

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.

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.
