Cyclic guanosine monophosphate–adenosine monophosphate
cyclic GMP-AMP (cGAMP) is identified by James Chen's Group at UT southwestern as the first cyclic di-nucleotide in metazoa.[1] In human and mouse cells, cGAMP is synthesized by Cyclic GMP-AMP synthase (cGAS) from ATP and GTP upon cytosolic DNA stimulation [2]. cGAMP produced by cGAS contained mixed phosphodiester linkages, with one between 2'-OH of GMP and 5'-phosphate of AMP and the other between 3'-OH of AMP and 5'-phosphate of GMP.[3] This molecule,abbreviated as 2′3′-cGAMP, functions as an endogenous second messenger inducing STING-dependent type I interferon response.[1]
