Introduction
3'3'-cGAMP, also known as cyclic [G(3', 5')pA(3', 5')p], is a bacterial-derived cyclic dinucleotide that functions as a crucial second messenger. Within bacteria, it mediates processes like chemotaxis and colonization. Notably, 3'3'-cGAMP possesses the ability to bind STING, triggering a signaling cascade involving TBK1 (TANK-binding kinase 1) and IRF3 (IFN regulatory transcription factor 3), ultimately leading to the production of IFN-β.
