Description

Description: 2',3'-cGAMP (sodium salt) is a second messenger generated by the enzyme cGAMP synthase (cGAS) in the cytoplasm of mammalian cells, in response to the presence of double-stranded DNA. As a second messenger, 2',3'-cGAMP sodium salt activates innate immune responses via binding of STING (stimulator of IFN genes) and initiates the TBK1-IRF3-dependent production of IFN-β. It is used to identify small compounds that bind to STING. It is also applicable in the research of type I interferon response to cytosolic DNA. The binding affinity of 2',3'-cGAMP to STING is 3.79 nM (Kd value), which is stronger than other cyclic di-nucleotides, e.g. cyclic di-GMP, 3'2'-cGAMP, 3'3'-cGAMP and 2'2'-cGAMP (Kds = 1.21 µM, 1.61 µM, 1.04 µM and 287 nM, respectively).
