Functional narrative    

HMG 17 is a nuclear protein of the HMG-14/HMG-17 protein family. In free solution HMG 17 has very little secondary or tertiary structure. The protein does not form an α-helix which could be expected from a 12% proline and 10% glycine content. There is no IR evidence for the formation of β-structure. HMG 17 is associated with the histones in nucleosomes and is believed to be a structural protein as well as an enhancer of transcriptional potential of chromatin. By modifying the structure of nucleosomes, HMG 17 affects the local structure of the chromatin leading to an increase in the rate of transcriptional elongation. HMG 17 undergoes its disorder to order transition when binding chromosomal DNA.
