Protein function

Nucleotidyltransferase that catalyzes the formation of cyclic GMP-AMP (cGAMP) from ATP and GTP. Catalysis 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]. Has antiviral activity by acting as a key cytosolic DNA sensor, the presence of double-stranded DNA (dsDNA) 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. cGAMP can be transferred between cells by virtue of packaging within viral particles contributing to IFN-induction in newly infected cells in a cGAS-independent but TMEM173/STING-dependent manner .

Protein tissue specificity

Expressed in the monocytic cell line THP1.

Protein sequence and domain

Belongs to the mab-21 family.

Protein post-translational modifications

Polyglutamylated by TTLL6 at Glu-286, leading to impair DNA-binding activity. Monoglutamylated at Glu-314 by TTLL4, leading to impair the nucleotidyltransferase activity. Deglutamylated by AGBL5/CCP5 and AGBL6/CCP6.

Protein cellular localization

Cytoplasm, cytosol .
