Histone - Wikipedia
网页Histone. Schematic representation of the assembly of the core histones into the nucleosome. In biology, histones are highly basic proteins abundant in lysine and arginine residues that are found in eukaryotic cell nuclei and in most Archaeal phyla.
Histone - National Human Genome Research Institute
网页4 天之前 · A histone is a protein that provides structural support for a chromosome. Each chromosome contains a long molecule of DNA, which must fit into the cell nucleus. To do that, the DNA wraps around complexes of histone proteins, giving the chromosome a more compact shape.

Histones: The critical players in innate immunity - PMC
网页2022年11月21日 · In addition to their antibacterial role in vivo, some studies showed that histones and their fragments can act as antimicrobial peptides (AMPs) — critical components of the ancient innate immune system that directly eliminate bacteria, viruses, fungi, and parasites in vitro.
