STING signals immune responses in human and other animals. STING is activated by cyclic GMP-AMP produced by Cyclic GMP-AMP synthase whose activity is triggered by infections of DNA-containing pathogens. A PLPLRT/SD conserved motif at the STING C-terminal plays a critical role in turning on the immune system to fight against viral infections. Disease STING mutations are associated with autoimmune diseases. Structural highlights The 3D structure of the complex between human STING and cyclic GMP-AMP shows the dinucleotide bound by the symmetric dimer of STING. The U-shaped cleft between the 2 subunits makes numerous interactions with the U-shaped ligand. A Tyr residue from each monomer stacks against each of the purine moieties while an Arg residue from each monomer forms hydrogen bonds to the dinucleotide .
