Abstract:
The HMG-box proteins, one of the three classes of high mobility group (HMG) chromosomal proteins, bend DNA and bind preferentially to distorted DNA structures. The proteins appear to act primarily as architectural facilitators in the assembly of nucleoprotein complexes; for example, in effecting recombination and in the initiation of transcription. HMG-box proteins might be targeted to particular DNA sites in chromatin by either protein-protein interactions or recognition of specific DNA structures.
