Histones are a family of basic proteins that form the core of the nucleosome – the fundamental structural unit of chromatin.  In a single nucleosome, core histone proteins H2A, H2B, H3, and H4 form an octamer around which the DNA is tightly wrapped. Histone proteins not only serve to compact chromosomal DNA but also play vital roles in the dynamic and long-term regulation of genes by a wide variety of post-translational modifications (PTMs). These PTMs including acetylation, methylation, phosphorylation, and novel acylations directly affect the accessibility of chromatin to transcription factors and other epigenetic regulators, altering genome stability and gene transcription. Among the histone members, histone H3 is the most extensively modified and its amino-terminal tail structure has been shown to be especially critical for eukaryotic cells.

Anti-Histone H3 Rabbit pAb detects endogenous levels of total histone H3 protein. It does not cross-react with other histone or non-histone proteins.
