Histones are alkaline (basic pH) proteins. They are found inside the nucleus of eukaryotic cells. Their purpose is to package DNA into structural units called nucleosomes.They are the main proteins in chromatin (a combination of DNA and protein), which makes up the contents of a cell nucleus.2A, H2B, H3, and H4 are the core histones, and H1 and H5 are the linker histones. The core histones form the center of the nucleosome, hence the term 'core'. The linker histones are found at the entrance and exit sites of the nucleosome and lock the DNA in place, hence the term 'linker'.
Five major families of histones exist: H1/H5, H2A, H2B, H3, and H4. Histones H2A, H2B, H3 and H4 are known as the core histones, while histones H1 and H5 are known as the linker histones. The core histones all exist as dimers, which are similar in that they all possess the histone fold domain; three alpha helices linked by two loops.
