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 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 high mobility group protein 20 (HMG20) subfamily; The HMG20 subfamily includes HMG20A and HMG20B. HMG20A, also called HMG box-containing protein 20A, HMG domain-containing protein 1, HMG domain-containing protein HMGX1, HMGXB1, or iBRAF, is a chromatin-associated protein involved in neuronal differentiation and maturation. It is required for SNAI1-mediated epithelial to mesenchymal transition. HMG20A acts as an inhibitor of HMG20B. HMG20B, also called SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily E member 1-related, SMARCE1-related protein (SMARCE1R), BRCA2-associated factor 35 (BRAF35), HMG box-containing protein 20B, HMG domain-containing protein 2, HMG domain-containing protein HMGX2, Sox-like transcriptional factor, or structural DNA-binding protein BRAF35, is a DNA binding factor that acts as a repressor of erythroid differentiation. It is required for correct progression through the G2 phase of the cell cycle and entry into mitosis. It is also required for RCOR1/CoREST mediated repression of neuronal specific gene promoters. HMG20B is a core subunit of the Lys-specific demethylase 1/REST co-repressor 1 (LSD1-CoREST) histone demethylase complex. Both HMG20A and HMG20B contain one HMG-box.

third 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 third one.

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 Arabidopsis thaliana FACT complex subunit SSRP1 and similar proteins; SSRP1, also called facilitates chromatin transcription complex subunit SSRP1, high mobility group B protein 8, nucleosome/chromatin assembly factor group D 08 (or D 8), protein NUCLEAR FUSION DEFECTIVE 8, or recombination signal sequence recognition protein 1, 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. 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.
