Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. Both the mouse and human H2a and H2b proteins consist of at least 10 non-allelic variants, making the complexity of the histone protein complement significantly greater than previously thought. HIST3H2A is intronless and encodes a member of the histone H2A family. Transcripts from this gene contain a palindromic termination element.
