  Function in Host
Nucleic acid-binding protein involved in innate immuneresponse to DNA and RNA viruses. Binds DNA and RNA in the cytoplasm and acts by promoting recognition ofviral nucleic acids by virus sensors, such as DDX58/RIG-I, IFIH1/MDA5and CGAS. Acts as a co-sensor forrecognition of double-stranded DNA (dsDNA) by cGAS in the cytoplasm, thereby playing a role in innate immune response to cytosolic dsDNA andDNA virus. Binds dsDNA and probably acts by promotingsensing of dsDNA by CGAS, leading to enhance CGAS oligomerization andactivation. Promotes sensing of viral RNA by RIG-I-like receptors proteins DDX58/RIG-I and IFIH1/MDA5 via two mechanisms:binds double-stranded RNA (dsRNA), enhancing the binding of DDX58/RIG-Iand IFIH1/MDA5 to dsRNA and promotes 'Lys-63'-linked ubiquitination andsubsequent activation of DDX58/RIG-I and IFIH1/MDA5.
