histone

 [his´tōn]
a simple protein, soluble in water and insoluble in dilute ammonia, found combined as salts with acidic substances, such as nucleic acids or the globin of hemoglobin.

his·tone (H),

(his'tōn),
One of a number of simple proteins (often found in the cell nucleus); contains a high proportion of basic amino acids; soluble in water, dilute acids, and alkalies; and not coagulable by heat; for example, the proteins associated with nucleic acids in the nuclei of plant and animal tissues. They constitute about half the mass of the chromosomes of eukaryotic cells.

histone

(hĭs′tōn′)
n.
Any of several basic proteins found in association with the DNA in the chromatin of eukaryotes.

histone

a type of simple protein that is usually basic and tends to form complexes with nucleic acids (e.g. DNA) forming NUCLEOSOMES. CHROMOSOMES of EUKARYOTES contain large quantities of histones which may regulate DNA functioning in some way. The five major histones are represented as: H1, H2A, H2B, H3 and H4.
