4o6a
Mouse cyclic GMP-AMP synthase (cGAS) in complex with DNAMouse cyclic GMP-AMP synthase (cGAS) in complex with DNA
FunctionFunction
[CGAS_MOUSE] Nucleotidyltransferase that catalyzes formation of cyclic GMP-AMP (cGAMP) from ATP and GTP and exhibits antiviral activity. Has antiviral activity by acting as a key cytosolic DNA sensor, the presence of DNA in the cytoplasm being a danger signal that triggers the immune responses. 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.
