Function

This gene encodes a member of the HIN-200 (hematopoietic interferon-inducible nuclear antigens with 200 amino acid repeats) family of cytokines. The encoded protein contains domains involved in DNA binding, transcriptional regulation, and protein-protein interactions. The protein localizes to the nucleoplasm and nucleoli, and interacts with p53.^[8] It modulates p53 function, and inhibits cell growth in the Ras/Raf signaling pathway.^[7] IFI16 has been shown to play a role in the sensing of intracellular DNA^[9] - a hallmark of virally infected cells - and has also been linked to the death of HIV-infected helper CD4 T cells by pyroptosis, a highly inflammatory form of programmed cell death.^[10][11] Recently, it has been shown how IFI16, once extracellularly released, can induce inflammation upon TLR4 binding, acting as a DAMP.^[12]
