WebCyclic GMP-AMP synthase (cGAS) is a cytosolic DNA sensor that detects the presence of nucleic acids in the cytosol of mammalian cells as an indicator of bacterial or viral infection.1cGAS catalyzes the synthesis of a second messenger, 2’3’-cGAMP, from cytosolic ATP and GTP in response to dsDNA binding. 2’3’-cGAMP then binds tightly to the adaptor … WebLike all RNA nucleotide-based second messengers that exist across all kingdoms of life (10), cGAMP is unable to passively enter or exit cells because of its two negatively charged phosphate...
