histone
histone Any of a group of water-soluble proteins found in association with the
DNA of plant and animal chromosomes. They contain a large proportion of the basic (positively charged) amino acids lysine, arginine, and histidine. They are involved in the condensation and coiling of chromosomes during cell division and have also been implicated in nonspecific suppression of gene activity (see
chromatin). Histones do not occur in vertebrate sperm cells (see
protamine) or in bacteria, although a very similar protein has been found in the genome of the archaebacterium Thermoplasma.
