Target description

High mobility group protein B1 (UniProt: P09429; also known as High mobility group protein 1, HMG-1) is encoded by the HMGB1 (also known as HMG1) gene (Gene ID: 3146) in human. HMG-1 is a ubiquitously distributed, multifunctional redox sensitive protein with various roles in different cellular compartments. In basal state predominantly nuclear. It shuttles between the cytoplasm and the nucleus. Translocates from the nucleus to the cytoplasm upon autophagy stimulation. In the nucleus, as one of the major chromatin-associated non-histone proteins, it acts as a DNA chaperone involved in replication, transcription, chromatin remodeling, V(D)J recombination, DNA repair, and genome stability. It promotes host inflammatory response to sterile and infectious signals and is involved in the coordination and integration of innate and adaptive immune responses. Its HMG box 1 and 2 regions are localized to amino acids 9-79 and 95-163, respectively. HMG box 2 is reported to mediate proinflammatory cytokine-stimulating activity and binding to TLR4. In the cytoplasm it dissociates the BECN1:BCL2 complex via competitive interaction with BECN1 leading to autophagy activation. It is also involved in oxidative stress-mediated autophagy. In its cytoplasmic role it also functions as sensor and/or chaperone for immunogenic nucleic acids implicating the activation of TLR9-mediated immune responses. It serves as a danger associated molecular pattern (DAMP) molecule that amplifies immune responses during tissue injury. In the extracellular compartment it is involved in regulation of the inflammatory response. It Induces the migration of monocyte-derived immature dendritic cells and regulates adhesive and migratory functions of neutrophils. HMG-1 is reported to contribute to the pathogenesis of various chronic inflammatory and autoimmune diseases, and cancer. High serum levels are reported in several inflammatory events including sepsis, rheumatoid arthritis, artherosclerosis chronic kidney disease, and systemic lupus erythematosus. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
