Histones

Small chromosomal proteins (approx 12-20 kD) possessing an open, unfolded structure and attached to the DNA in cell nuclei by ionic linkages. Classification into the various types (designated histone I, histone II, etc.) is based on the relative amounts of arginine and lysine in each.

Also Known As:

Histone; Histone H1; Histone H3; Histone H2a; Histone H4; Histone H2b; Histone H3.3; Histone H1(s); Histone H5; Histone H7
