HU, or H-NS (Histone-like Nucleoid Structuring) protein, is a DNA-binding protein found in prokaryotic cells that plays a crucial role in the organization and structure of the bacterial chromosome during cell division. It aids in compaction and segregation of DNA, ensuring that genetic material is properly distributed to daughter cells. Additionally, HU is involved in several cellular processes including DNA replication and repair, making it essential for maintaining cellular integrity during prokaryotic cell division.
