General description

Cyclic GMP-AMP synthase (cGAS), also known as cGAMP synthase, h-cGAS, Mab-21 domain-containing protein 1, and encoded by the gene name MB21D1 and C6orf150, is a member of the MAB-21 family. Cyclic GMP-AMP synthase (cGAS) is a nucleotidyltransferase that catalyzes the formation of cyclic GMP-AMP (cGAMP) from ATP and GTP. The catalysis process involves both the formation of a 2′,5′ phosphodiester linkage at the GpA step and the formation of a 3′,5′ phosphodiester linkage at the ApG step, producing c[G(2′,5′)pA(3′,5′)p]. Recent studies have indicated that Cyclic GMP-AMP synthase (cGAS) has an antiviral activity by acting as a key cytosolic DNA sensor, when the presence of double-stranded DNA (dsDNA) in the cytoplasm acts as a danger signal that triggers the immune responses. Cyclic GMP-AMP synthase (cGAS) then binds cytosolic DNA directly, leading to activation and synthesis of cGAMP, a second messenger that binds to and activates TMEM173/STING, thereby triggering type-I interferon production. Cyclic GMP-AMP synthase (cGAS) is expressed in the monocytic cell line THP1.
