Webb1. Basic histone biology. Histones are structural subunits that provide a core in which chromatin can be wrapped around. The core comprises of two H2A–H2B dimers and an (H3–H4) 2 tetramer (histone octamer) with an external H1 histone, a conserved subunit that assists with maintaining this ‘beads on a string’ structure [Citation 1].The histone …

Histone H4 is one of the slowest evolving proteins. There are H4 genes that are constitutively expressed throughout the cell cycle that encode for proteins that are identical in sequence to the major H4. Variants in human histone H4 were only recently discovered and are very rare.
