CC   -!- FUNCTION: Multifunctional redox sensitive protein with various roles in
CC       different cellular compartments. In the nucleus is one of the major
CC       chromatin-associated non-histone proteins and acts as a DNA chaperone
CC       involved in replication, transcription, chromatin remodeling, V(D)J
CC       recombination, DNA repair and genome stability (PubMed:33147444).
CC       Proposed to be an universal biosensor for nucleic acids. Promotes host
CC       inflammatory response to sterile and infectious signals and is involved
CC       in the coordination and integration of innate and adaptive immune
CC       responses. In the cytoplasm functions as a sensor and/or chaperone for
CC       immunogenic nucleic acids implicating the activation of TLR9-mediated
CC       immune responses, and mediates autophagy. Acts as a danger-associated
CC       molecular pattern (DAMP) molecule that amplifies immune responses
CC       during tissue injury (PubMed:27362237). Released to the extracellular
CC       environment can bind DNA, nucleosomes, IL-1 beta, CXCL12, AGER isoform
CC       2/sRAGE, lipopolysaccharide (LPS) and lipoteichoic acid (LTA), and
CC       activates cells through engagement of multiple surface receptors
CC       (PubMed:34743181). In the extracellular compartment fully reduced HMGB1
CC       (released by necrosis) acts as a chemokine, disulfide HMGB1 (actively
CC       secreted) as a cytokine, and sulfonyl HMGB1 (released from apoptotic
CC       cells) promotes immunological tolerance (PubMed:23519706,
CC       PubMed:23446148, PubMed:23994764, PubMed:25048472). Has proangiogdenic
CC       activity (By similarity). May be involved in platelet activation (By
CC       similarity). Binds to phosphatidylserine and phosphatidylethanolamide
CC       (By similarity). Bound to RAGE mediates signaling for neuronal
CC       outgrowth (By similarity). May play a role in accumulation of expanded
CC       polyglutamine (polyQ) proteins such as huntingtin (HTT) or TBP
CC       (PubMed:23303669, PubMed:25549101). {ECO:0000250|UniProtKB:P10103,

CC   -!- FUNCTION: Nuclear functions are attributed to fully reduced HGMB1.
CC       Associates with chromatin and binds DNA with a preference to non-
CC       canonical DNA structures such as single-stranded DNA, DNA-containing
CC       cruciforms or bent structures, supercoiled DNA and ZDNA. Can bent DNA
CC       and enhance DNA flexibility by looping thus providing a mechanism to
CC       promote activities on various gene promoters by enhancing transcription
CC       factor binding and/or bringing distant regulatory sequences into close
CC       proximity (PubMed:20123072). May have an enhancing role in nucleotide
CC       excision repair (NER) (By similarity). However, effects in NER using in
CC       vitro systems have been reported conflictingly (PubMed:19446504,
CC       PubMed:19360789). May be involved in mismatch repair (MMR) and base
CC       excision repair (BER) pathways (PubMed:15014079, PubMed:16143102,
CC       PubMed:17803946). May be involved in double strand break repair such as
CC       non-homologous end joining (NHEJ) (By similarity). Involved in V(D)J
CC       recombination by acting as a cofactor of the RAG complex: acts by
CC       stimulating cleavage and RAG protein binding at the 23 bp spacer of
CC       conserved recombination signal sequences (RSS) (By similarity). In
CC       vitro can displace histone H1 from highly bent DNA (By similarity). Can
CC       restructure the canonical nucleosome leading to relaxation of
CC       structural constraints for transcription factor-binding (By
CC       similarity). Enhances binding of sterol regulatory element-binding
CC       proteins (SREBPs) such as SREBF1 to their cognate DNA sequences and
CC       increases their transcriptional activities (By similarity). Facilitates
CC       binding of TP53 to DNA (PubMed:23063560). Proposed to be involved in
CC       mitochondrial quality control and autophagy in a transcription-
CC       dependent fashion implicating HSPB1; however, this function has been
CC       questioned (By similarity). Can modulate the activity of the telomerase
CC       complex and may be involved in telomere maintenance (By similarity).

CC   -!- FUNCTION: In the cytoplasm proposed to dissociate the BECN1:BCL2
CC       complex via competitive interaction with BECN1 leading to autophagy
CC       activation (PubMed:20819940). Involved in oxidative stress-mediated
CC       autophagy (PubMed:21395369). Can protect BECN1 and ATG5 from calpain-
CC       mediated cleavage and thus proposed to control their proautophagic and
CC       proapoptotic functions and to regulate the extent and severity of
CC       inflammation-associated cellular injury (By similarity). In myeloid
CC       cells has a protective role against endotoxemia and bacterial infection
CC       by promoting autophagy (By similarity). Involved in endosomal
CC       translocation and activation of TLR9 in response to CpG-DNA in
CC       macrophages (By similarity). {ECO:0000250|UniProtKB:P63158,
CC       ECO:0000269|PubMed:20819940, ECO:0000269|PubMed:21395369}.
CC   -!- FUNCTION: In the extracellular compartment (following either active
CC       secretion or passive release) involved in regulation of the
CC       inflammatory response. Fully reduced HGMB1 (which subsequently gets
CC       oxidized after release) in association with CXCL12 mediates the
CC       recruitment of inflammatory cells during the initial phase of tissue
CC       injury; the CXCL12:HMGB1 complex triggers CXCR4 homodimerization
CC       (PubMed:22370717). Induces the migration of monocyte-derived immature
CC       dendritic cells and seems to regulate adhesive and migratory functions
CC       of neutrophils implicating AGER/RAGE and ITGAM (By similarity). Can
CC       bind to various types of DNA and RNA including microbial unmethylated
CC       CpG-DNA to enhance the innate immune response to nucleic acids.
CC       Proposed to act in promiscuous DNA/RNA sensing which cooperates with
CC       subsequent discriminative sensing by specific pattern recognition
CC       receptors (By similarity). Promotes extracellular DNA-induced AIM2
CC       inflammasome activation implicating AGER/RAGE (PubMed:24971542).
CC       Disulfide HMGB1 binds to transmembrane receptors, such as AGER/RAGE,
CC       TLR2, TLR4 and probably TREM1, thus activating their signal
CC       transduction pathways. Mediates the release of cytokines/chemokines
CC       such as TNF, IL-1, IL-6, IL-8, CCL2, CCL3, CCL4 and CXCL10
CC       (PubMed:12765338, PubMed:18354232, PubMed:19264983, PubMed:20547845,
CC       PubMed:24474694). Promotes secretion of interferon-gamma by macrophage-
CC       stimulated natural killer (NK) cells in concert with other cytokines
CC       like IL-2 or IL-12 (PubMed:15607795). TLR4 is proposed to be the
CC       primary receptor promoting macrophage activation and signaling through
CC       TLR4 seems to implicate LY96/MD-2 (PubMed:20547845). In bacterial
CC       LPS- or LTA-mediated inflammatory responses binds to the endotoxins and
CC       transfers them to CD14 for signaling to the respective TLR4:LY96 and
CC       TLR2 complexes (PubMed:18354232, PubMed:21660935, PubMed:25660311).
CC       Contributes to tumor proliferation by association with ACER/RAGE (By
CC       similarity). Can bind to IL1-beta and signals through the IL1R1:IL1RAP
CC       receptor complex (PubMed:18250463). Binding to class A CpG activates
CC       cytokine production in plasmacytoid dendritic cells implicating TLR9,
CC       MYD88 and AGER/RAGE and can activate autoreactive B cells. Via HMGB1-
CC       containing chromatin immune complexes may also promote B cell responses
CC       to endogenous TLR9 ligands through a B-cell receptor (BCR)-dependent
CC       and ACER/RAGE-independent mechanism (By similarity). Inhibits
CC       phagocytosis of apoptotic cells by macrophages; the function is
CC       dependent on poly-ADP-ribosylation and involves binding to
CC       phosphatidylserine on the cell surface of apoptotic cells (By
CC       similarity). In adaptive immunity may be involved in enhancing immunity
CC       through activation of effector T cells and suppression of regulatory T
CC       (TReg) cells (PubMed:15944249, PubMed:22473704). In contrast, without
CC       implicating effector or regulatory T-cells, required for tumor
CC       infiltration and activation of T-cells expressing the lymphotoxin
CC       LTA:LTB heterotrimer thus promoting tumor malignant progression (By
CC       similarity). Also reported to limit proliferation of T-cells (By
CC       similarity). Released HMGB1:nucleosome complexes formed during
CC       apoptosis can signal through TLR2 to induce cytokine production
CC       (PubMed:19064698). Involved in induction of immunological tolerance by
CC       apoptotic cells; its pro-inflammatory activities when released by
CC       apoptotic cells are neutralized by reactive oxygen species (ROS)-
CC       dependent oxidation specifically on Cys-106 (PubMed:18631454). During
CC       macrophage activation by activated lymphocyte-derived self apoptotic
CC       DNA (ALD-DNA) promotes recruitment of ALD-DNA to endosomes (By
CC       similarity). {ECO:0000250|UniProtKB:P10103,

CC   -!- DOMAIN: HMG box 2 mediates pro-inflammatory cytokine-stimulating
CC       activity and binding to TLR4 (PubMed:12765338, PubMed:20547845).
CC       However, not involved in mediating immunogenic activity in the context
CC       of apoptosis-induced immune tolerance (PubMed:24474694).
CC       {ECO:0000269|PubMed:12765338, ECO:0000269|PubMed:20547845,
CC       ECO:0000269|PubMed:24474694}.
CC   -!- DOMAIN: The acidic C-terminal domain forms a flexible structure which
CC       can reversibly interact intramolecularily with the HMG boxes and
CC       modulate binding to DNA and other proteins (PubMed:23063560).
CC       {ECO:0000250|UniProtKB:P63159, ECO:0000305|PubMed:23063560}.
CC   -!- PTM: Phosphorylated at serine residues. Phosphorylation in both NLS
CC       regions is required for cytoplasmic translocation followed by secretion
CC       (PubMed:17114460). {ECO:0000269|PubMed:17114460}.
CC   -!- PTM: Acetylated on multiple sites upon stimulation with LPS
CC       (PubMed:22801494). Acetylation on lysine residues in the nuclear
CC       localization signals (NLS 1 and NLS 2) leads to cytoplasmic
CC       localization and subsequent secretion (By similarity). Acetylation on
CC       Lys-3 results in preferential binding to DNA ends and impairs DNA
CC       bending activity (By similarity). {ECO:0000250|UniProtKB:P10103,
CC       ECO:0000250|UniProtKB:P63159, ECO:0000269|PubMed:22801494}.
CC   -!- PTM: Reduction/oxidation of cysteine residues Cys-23, Cys-45 and Cys-
CC       106 and a possible intramolecular disulfide bond involving Cys-23 and
CC       Cys-45 give rise to different redox forms with specific functional
CC       activities in various cellular compartments: 1- fully reduced HMGB1
CC       (HMGB1C23hC45hC106h), 2- disulfide HMGB1 (HMGB1C23-C45C106h) and
CC       3- sulfonyl HMGB1 (HMGB1C23soC45soC106so).
CC       {ECO:0000269|PubMed:16962095, ECO:0000269|PubMed:19811284,
CC       ECO:0000269|PubMed:22869893, ECO:0000305|PubMed:24531895}.
CC   -!- PTM: Poly-ADP-ribosylated by PARP1 when secreted following stimulation
CC       with LPS (By similarity). {ECO:0000250|UniProtKB:P63158}.
CC   -!- PTM: In vitro cleavage by CASP1 is liberating a HMG box 1-containing
CC       peptide which may mediate immunogenic activity; the peptide antagonizes
CC       apoptosis-induced immune tolerance (PubMed:24474694). Can be
CC       proteolytically cleaved by a thrombin:thrombomodulin complex; reduces
CC       binding to heparin and pro-inflammatory activities (By similarity).
CC       {ECO:0000250|UniProtKB:P10103, ECO:0000269|PubMed:24474694}.
CC   -!- PTM: Forms covalent cross-links mediated by transglutaminase TGM2,
CC       between a glutamine and the epsilon-amino group of a lysine residue,
CC       forming homopolymers and heteropolymers. {ECO:0000269|PubMed:29618516}.
CC   -!- MISCELLANEOUS: Proposed to contribute to the pathogenesis of various
CC       chronic inflammatory and autoimmune diseases, and cancer. High serum
CC       levels are found in several inflammatory events including sepsis,
CC       rheumatoid arthritis, artherosclerosis chronic kidney disease, systemic
CC       lupus erythematosus (SLE). Seems to be implicated in other diseases
CC       characterized by cell death and damage, including diabetes and
CC       Alzheimer's disease. Its nucleosome-associated release during secondary
CC       necrosis may play a role in SLE (PubMed:19064698). During chemotherapy
CC       can mediate regrowth and metastasis of remaining cells in a AGER/RAGE-
CC       dependent manner (PubMed:23040637). Purified HMG box 1 acts as a
CC       specific antagonist to HGMB1 pro-inflammatory activities
CC       (PubMed:14695889). {ECO:0000269|PubMed:14695889,
CC       ECO:0000269|PubMed:23040637, ECO:0000305, ECO:0000305|PubMed:19064698,
CC       ECO:0000305|PubMed:24220159, ECO:0000305|PubMed:26078984}.
CC   -!- SIMILARITY: Belongs to the HMGB family. {ECO:0000305}.
CC   -!- CAUTION: Inconsistent experimental results may reflect the use of
CC       inconsistently defined redox forms. A recombinant fully reduced form
CC       has been used in a number of experiments. However, the redox states of
CC       HMGB1 administered in vivo, may interconvert among each other. Purified
CC       HMGB1 by itself has only weak pro-inflammatory activity. {ECO:0000305}.
