Histoni su osnovni jedarni proteini koji su odgovorni za nukleosomsku strukturu hromosomskog vlakna u eukariotima . Nukleosomi se sastoje od približno 146 bp DNK omotane oko histonskog oktamera , sastavljenog od parova svakog od četiri jezgra histona (H2A, H2B, H3 i H4). Hromatinsko vlakno se dalje sabija kroz interakciju histonskog linkera H1 , sa DNK između nukleosoma, kako bi se formirale strukture hromatina višeg reda. Ovaj gen je bez introna i kodira člana porodice histoni H2A . Transkripti ovog gena sadrže palindromski terminacijski element.[6]
