Gene Name:
H2A clustered histone 21

h2a , XH2AX , H2AX , hist2h2ab ( Add synonyms , Nomenclature history )

Gene Function:
Histone 2A

Protein Function :
Variant histone H2A which replaces conventional H2A in a subset of nucleosomes. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA...[+]
