  • Details

    STING Ligand. Cyclic [G(3’,5’)pA(3’,5’)p]. 3’3’-cGAMP (cyclic [G(3’,5’)pA(3’,5’)p], previously known as cGAMP) is a cyclic di-nucleotide produced by bacteria. 3’3’-cGAMP is also referred to as "canonical" cGAMP due the presence of the classical 3’-5’ phosphodiester linkages between the guanosine and the adenosine. Recently, 3’3’-cGAMP was reported to bind STING (stimulator of IFN genes) and subsequently induce TBK1-IRF3-dependent production of IFN-β [1]. Studies in bacteria revealed that 3’3’-cGAMP serves as a second messenger and plays a role in bacterial chemotaxis and colonization [2]. Structural and functional studies revealed that the canonical 3’3’-cGAMP produced by bacteria is distinct from the noncanonical 2’3’-cGAMP produced by mammalian cGAS [3]. Certain variants of STING are able to distinguish between canonical and noncanonical cGAMP [4]. 3’3’-cGAMP is more potent in activating IRF3 than c-di-IMP, c-di-AMP and c-diGMP, other 3',5' cyclic dinucleotides that also bind to STING [5].
