Histone H4 Antibodies and Proteins

Histones are highly conserved proteins that serve as the structural scaffold for the organization of nuclear DNA into chromatin. The histones have an amino terminal tail, a globular domain, and a carboxy-terminal tail. The four core histones, H2A, H2B, H3 and H4 assemble into the octamer (2 molecules of each). Subsequently, 146 base pairs of DNA are wrapped in a sequence-independent manner around the octamer, forming the basic subunit of chromatin, the nucleosome. Histone H4 is one of the 5 main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N terminal tail H4 is involved with the structure of the nucleosomes of the 'beads on a string' structure.
