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 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.

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.

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.

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.
