NCBI Summary for IFI16
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 and retinoblastoma-1. It modulates p53 function, and inhibits cell growth in the Ras/Raf signaling pathway. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2011]
UniProt Comments for IFI16
IFI16: a nuclear protein that may function as a transcriptional repressor. Strongly induced by gamma interferon and, to a lesser extent, by alpha interferon. Binds double-stranded DNA and cell cycle regulatory factors including p53 and Rb. Loss of IFI16 activates p53 checkpoint through NBS1-DNAPK pathway. Inhibits cell growth in the Ras/Raf signaling pathway. May be involved in the senescence of prostate epithelial cells. Expressed in peripheral blood leukocytes, fibroblasts and lymphoid cells. Present in myeloid precursors (CD34+) and throughout monocyte development, but its expression is down-regulated in erythroid and polymorphonuclear precursor cells. Present in prostate, ovary and breast. Four alternatively spliced isoforms have been described. Isoforms-1, -2 and -3 can homo- and hetero-dimerize.
