Schematic representation of HMGB1 structure. HMGB1 has 215 amino acids organized in two proximal homologous DNA binding domains, A-box, B-box, and a C-terminal acidic tail with repeated acid residues. HMGB1 has two nuclear localization signals (NLS1 and NLS2), one TLR-binding domain and one RAGE-binding domain.
