|HMG (high mobility group) box|
|SCOPe||1hsm / SUPFAM|
HMG-box containing proteins only bind non-B-type DNA conformations (kinked or unwound) with high affinity. HMG-box domains are found in high mobility group proteins, which are involved in the regulation of DNA-dependent processes such as transcription, replication, and DNA repair, all of which require changing the conformation of chromatin. The single and the double box HMG proteins alter DNA architecture by inducing bends upon binding.
