HIRA（histone cell cycle regulator) encodes a histone chaperone that preferentially places the variant histone H3.3 in nucleosomes. Orthologs of HIRA 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.

Phospho-HIRA (T555) Polyclonal Antibody detects endogenous levels of HIRA protein only when phosphorylated at T555.

Optimal working dilutions should be determined experimentally by the investigator. Suggested starting dilutions are as follows: IHC-p: 1:100-1:300, IF: 1:200-1:1000, ELISA: 1:10000. Not yet tested in other applications.
