2’3’-cGAMP is a second messenger produced from ATP and GTP by cGMP-AMP synthase (cGAS) in the cytoplasm of mammalian cells in response to the presence of DNA.{22401,22400,29220} It contains a non-canonical 2’5’-phosphodiester bond and binds tightly to the adapter protein STING (stimulator of interferon genes) with a Kd value of 3.79 nM, which is significantly lower than that observed for 2’2’-cGAMP, 3’3’-cGAMP (Item No. 17966), cyclic di-GMP (Item No. 17144), and 3’2’-cGAMP (Kds = 0.287, 1.04, 1.21, and 1.61 µM, respectively).{29220} It is a potent inducer of IFN-? mRNA expression with an EC50 value of 19.4 nM in L929 cells.{29220}
