HIRA

Human gene and protein From Wikipedia, the free encyclopedia

Protein HIRA is a protein that in humans is encoded by the HIRA gene.[5][6][7][8] This gene is mapped to 22q11.21, centromeric to COMT.[8]

Function

The specific function of this protein has yet to be determined; however, it has been speculated to play a role in transcriptional regulation and/or chromatin and histone metabolism.[8]

Research done by Salomé Adam, Sophie E. Polo, and Geneviève Almouzni indicate that HIRA proteins are involved in restarting transcription after UVC damage.[9] Function of HIRA gene can be effectively examined by siRNA knockdown based on an independent validation.[10]

Clinical significance

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.[8]

Interactions

HIRA has been shown to interact with HIST1H2BK.[11]
