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 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.

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.
