This gene encodes a histone chaperone that preferentially places the variant histone H3.3 in nucleosomes. Orthologs of this gene in yeast, flies, and plants are necessary for the formation of transcriptionally silent heterochomatin. This gene plays an important role in the formation of the senescence-associated heterochromatin foci. These foci likely mediate the irreversible cell cycle changes that occur in senescent cells. It is considered the primary candidate gene in some haploinsufficiency syndromes such as DiGeorge syndrome, and insufficient production of the gene may disrupt normal embryonic development.

HIRA (Histone Cell Cycle Regulator) is a Protein Coding gene. Diseases associated with HIRA include Digeorge Syndrome and Velocardiofacial Syndrome. Among its related pathways are Chromatin Regulation / Acetylation and DNA Damage/Telomere Stress Induced Senescence. Gene Ontology (GO) annotations related to this gene include DNA-binding transcription factor activity and transcription corepressor activity.
