HMG-1 (High-Mobility-Group protein, amphoterin) is a highly conserved protein with more than 95% amino acid identity between rodent and human HMG-1. It is a prevalent non-histone chromatin component and a non-sequence specific DNA binding protein. HMG-1 consists of two homologous HMG boxes rich in basic amino acids and an acidic tail at the carboxy-terminus. HMG-1 is involved in the regulation of chromatin structure as well as being involved, either as positive or negative factors with various aspects of DNA replication, transcription, repair, and ligation. HMG-1, identified as a membrane associated protein termed “amphoterin,” mediates neurite outgrowth, tumor outgrowth, and metastasis. It participates in plasminogen activation and is recognized as a late mediator of endotoxin lethality in mice.
