The HMG proteins are subdivided into 3 superfamilies each containing a characteristic functional domain:
- TCF Transcription Factors
- Lymphoid enhancer-binding factor 1
- T Cell Transcription Factor 1
HMG proteins are thought to play a significant role in various human disorders. Disruptions and rearrangements in the genes coding for some of the HMG proteins are associated with some common benign tumors. Antibodies to HMG proteins are found in patients suffering from autoimmune diseases. The SRY gene on the Y Chromosome, responsible for male sexual differentiation, contains an HMG-Box domain. A member of the HMG family of proteins, HMGB1, has also been shown to have an extracellular activity as a chemokine, attracting neutrophils and mononuclear inflammatory cells to the infected liver.
