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] (PubMed:28363908, PubMed:28214358). Acts 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 (PubMed:28363908). 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 (PubMed:28363908, PubMed:28314590). Preferentially recognizes and binds curved long DNAs (PubMed:30007416). In contrast to other mammals, human CGAS displays species-specific mechanisms of DNA recognition and produces less cyclic GMP-AMP (cGAMP), allowing a more fine-tuned response to pathogens (PubMed:30007416). Has antiviral activity by sensing the presence of dsDNA from DNA viruses in the cytoplasm (PubMed:28363908). Also acts as an innate immune sensor of infection by retroviruses, such as HIV-1, by detecting the presence of reverse-transcribed DNA in the cytosol (PubMed:23929945). Detection of retroviral reverse-transcribed DNA in the cytosol may be indirect and be mediated via interaction with PQBP1, which directly binds reverse-transcribed retroviral DNA (PubMed:26046437). Also detects the presence of DNA from bacteria, such as M.tuberculosis (PubMed:26048138). cGAMP can be transferred from producing cells to neighboring cells through gap junctions, leading to promote TMEM173\/STING activation and convey immune response to connecting cells (PubMed:24077100).\u003c\/p\u003e\n\n\u003cp\u003eConcentration: 1mg\/mL\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: A synthetic peptide of human cGAS\u003c\/p\u003e\n\n\u003cp\u003eBuffer: PBS with 0.02% sodium azide, 50% glycerol, pH7.3.\u003c\/p\u003e\n\n\u003cp\u003ePurification Method: Affinity purification\u003c\/p\u003e\n\n\u003cp\u003eDilution: WB 1:500-1:2000\u003c\/p\u003e\n\n\u003cp\u003eCalculated MW: 49kDa\/58kDa\u003c\/p\u003e\n\n \n\n\u003cp\u003eStorage: -20°C\/One year.
