Background

IFI16 belongs to the PYHIN family, which consists of four members in humans (Aim2, IFIX, MNDA, and IFI16) and at least thirteen members in mice (1). The closest homolog of IFI16 in mice is p204. The PYHIN family is characterized by the presence of one or two HIN-200 domains that bind double stranded DNA and a PYRIN domain that mediates interactions among family members, as well as the inflammasome-forming ASC protein (1). IFI16 also has a nuclear localization signal, but has been observed to bind DNA in both the cytoplasm and nucleus (2,3). There are three isoforms of IFI16 produced by alternative splicing (4). IFI16 is constitutively expressed by some cells, such as lymphocytes, and highly inducible in many others by interferons (5). IFI16 has been shown to directly interact with p53 and to play a role in cellular senescence by modulating p53 activity (6). IFI16 was shown to directly sense intracellular viral DNA, leading to recruitment of STING and activation of IRF-3 and NF-κB (2). Investigators have observed increased levels of IFI16 and anti-IFI16 autoantibodies in patients with systemic lupus erythematosus (7-9).
