Gene information for HIRA (Homo sapiens)
(Information is obtained from NCBI Gene database)
Entrez gene ID7290
Official gene symbolHIRA
Full nameHIR histone cell cycle regulation defective homolog A (S. cerevisiae)
Aliases,DGCR1,TUP1,TUPLE1,
Gene summaryThis 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.
