FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a five transmembrane protein that functions as a major regulator of the innate immune response to viral and bacterial infections. The encoded protein is a pattern recognition receptor that detects cytosolic nucleic acids and transmits signals that activate type I interferon responses. The encoded protein has also been shown to play a role in apoptotic signaling by associating with type II major histocompatibility complex. Mutations in this gene are the cause of infantile-onset STING-associated vasculopathy. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2014]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit increased susceptibility to viral infection and abnormal innate immunity. Mice homozygous for an ENU-induced allele exhibit altered response to bacterial and viral infection. [provided by MGI curators]
