The Neisseria sp. protein DMP12 has been shown to interact with the bacterial histone-like protein HU and may do so by acting as a DNA mimic. It is likely to play a regulatory role, but not via direct competition for binding of HU, which is involved in maintenance of the bacterial nucleoid structure.
