WebUpon binding to the double-stranded DNA (dsDNA), cGAS synthesizes cGAMP, a second-messenger molecule that binds to the adaptor protein stimulator of IFN genes (STING) and induces a conformational change in the STING dimer. Web18 dec. 2009 · Ishikawa and Barber (2008) concluded that STING was involved in RIG-I-mediated type I IFN induction but did not affect the TLR pathway. Although STING interacted directly with RIG-I, it did not co-immunoprecipitate with MDA-5. Loss of STING rendered cells unable to induce IFNβ production in response to transfected B-form DNA …
