CC -!- FUNCTION: Nucleotidyltransferase that catalyzes the formation of cyclic
CC GMP-AMP (2',3'-cGAMP) from ATP and GTP and plays a key role in innate
CC immunity (PubMed:23258413, PubMed:23647843, PubMed:23722158,
CC PubMed:26829768, PubMed:28214358, PubMed:29625897, PubMed:29426904,
CC PubMed:32814054). Catalysis involves both the formation of a 2',5'
CC phosphodiester linkage at the GpA step and the formation of a 3',5'
CC phosphodiester linkage at the ApG step, producing c[G(2',5')pA(3',5')p]
CC (PubMed:23258413, PubMed:23647843, PubMed:23722158, PubMed:26829768,
CC PubMed:28214358). Acts as a key DNA sensor: directly binds double-
CC stranded DNA (dsDNA), inducing the formation of liquid-like droplets in
CC which CGAS is activated, leading to synthesis of 2',3'-cGAMP, a second
CC messenger that binds to and activates STING1, thereby triggering type-I
CC interferon production (PubMed:23722158, PubMed:28314590,
CC PubMed:28363908, PubMed:28095500). Preferentially binds long dsDNA
CC (around 45 bp) and forms ladder-like networks that function
CC cooperatively to stabilize individual cGAS-dsDNA complexes
CC (PubMed:28902841). Acts as a key foreign DNA sensor, the presence of
CC double-stranded DNA (dsDNA) in the cytoplasm being a danger signal that
CC triggers the immune responses (PubMed:23722158, PubMed:28314590,
CC PubMed:28363908). Has antiviral activity by sensing the presence of
CC dsDNA from DNA viruses in the cytoplasm (PubMed:23258413,
CC PubMed:23722158, PubMed:23647843). Also acts as an innate immune sensor
CC of infection by retroviruses by detecting the presence of reverse-
CC transcribed DNA in the cytosol (PubMed:23929945). Detection of
CC retroviral reverse-transcribed DNA in the cytosol may be indirect and
CC be mediated via interaction with PQBP1, which directly binds reverse-
CC transcribed retroviral DNA (By similarity). Also detects the presence
CC of DNA from bacteria (By similarity). 2',3'-cGAMP can be transferred
CC from producing cells to neighboring cells through gap junctions,
CC leading to promote STING1 activation and convey immune response to
CC connecting cells (PubMed:24077100). 2',3'-cGAMP can also be transferred
CC between cells by virtue of packaging within viral particles
CC contributing to IFN-induction in newly infected cells in a cGAS-
CC independent but STING1-dependent manner (PubMed:26229117). Also senses
CC the presence of neutrophil extracellular traps (NETs) that are
CC translocated to the cytosol following phagocytosis, leading to
CC synthesis of 2',3'-cGAMP (PubMed:33688080). In addition to foreign DNA,
CC can also be activated by endogenous nuclear or mitochondrial DNA (By
CC similarity). When self-DNA leaks into the cytosol during cellular
CC stress (such as mitochondrial stress, DNA damage, mitotic arrest or
CC senescence), or is present in form of cytosolic micronuclei, CGAS is
CC activated leading to a state of sterile inflammation (PubMed:28738408,
CC PubMed:28759028). Acts as a regulator of cellular senescence by binding
CC to cytosolic chromatin fragments that are present in senescent cells,
CC leading to trigger type-I interferon production via STING1 and promote
CC cellular senescence (PubMed:28759028). Also involved in the
CC inflammatory response to genome instability and double-stranded DNA
CC breaks: acts by localizing to micronuclei arising from genome
CC instability (PubMed:28738408). Micronuclei, which as frequently found
CC in cancer cells, consist of chromatin surrounded by its own nuclear
CC membrane: following breakdown of the micronuclear envelope, a process
CC associated with chromothripsis, CGAS binds self-DNA exposed to the
CC cytosol, leading to 2',3'-cGAMP synthesis and subsequent activation of
CC STING1 and type-I interferon production (PubMed:28738408). In a healthy
CC cell, CGAS is however kept inactive even in cellular events that
CC directly expose it to self-DNA, such as mitosis, when cGAS associates
CC with chromatin directly after nuclear envelope breakdown or remains in
CC the form of postmitotic persistent nuclear cGAS pools bound to
CC chromatin (By similarity). Nuclear CGAS is inactivated by chromatin via
CC direct interaction with nucleosomes, which block CGAS from DNA binding
CC and thus prevent CGAS-induced autoimmunity (PubMed:31808743,
CC PubMed:32911481, PubMed:32911480, PubMed:32913000). Also acts as a
CC suppressor of DNA repair in response to DNA damage: inhibits homologous
CC recombination repair by interacting with PARP1, the CGAS-PARP1
CC interaction leading to impede the formation of the PARP1-TIMELESS
CC complex (PubMed:30356214, PubMed:31544964). In addition to DNA, also
CC sense translation stress: in response to translation stress,
CC translocates to the cytosol and associates with collided ribosomes,
CC promoting its activation and triggering type-I interferon production
CC (By similarity). {ECO:0000250|UniProtKB:Q8N884,

CC -!- ACTIVITY REGULATION: The enzyme activity is strongly increased by
CC double-stranded DNA (dsDNA), but not by single-stranded DNA or RNA (By
CC similarity). DNA-binding induces the formation of liquid-like droplets
CC in which CGAS is activated (By similarity). Liquid-like droplets also
CC create a selective environment that restricts entry of negative
CC regulators, such as TREX1 or BANF1/BAF, allowing sensing of DNA (By
CC similarity). A number of mechanisms exist to restrict its activity
CC toward self-DNA (PubMed:32911481, PubMed:32911480, PubMed:32913000).
CC The nucleotidyltransferase activity is inhibited in the nucleus via its
CC association with nucleosomes: interacts with the acidic patch of
CC histones H2A and H2B, thereby blocking DNA-binding and subsequent
CC activation (PubMed:32156810, PubMed:32911481, PubMed:32911480,
CC PubMed:32913000). CGAS is also inactive when associated with mitotic
CC chromatin (By similarity). Chromatin-bound CGAS cannot be activated by
CC exogenous DNA in mitotic cells: phosphorylation of the N-terminal
CC disordered part by AURKB during the G2-M transition blocks CGAS liquid
CC phase separation and activation (By similarity). Activity toward self-
CC DNA is inhibited by BANF1/BAF upon acute loss of nuclear membrane
CC integrity: BANF1/BAF acts by outcompeting CGAS for DNA-binding, thereby
CC preventing CGAS activation (PubMed:32156810). DNA-induced activation at
CC micronuclei is also limited by TREX1, which degrades micronuclear DNA
CC upon nuclear envelope rupture, thereby preventing CGAS activation (By
CC similarity). Acetylation at Lys-372, Lys-382 and Lys-402 inhibits the
CC cyclic GMP-AMP synthase activity (By similarity). Acetylation by KAT5
CC increases the cyclic GMP-AMP synthase activity by promoting DNA-binding
CC and subsequent activation (By similarity). Phosphorylation at Ser-291
CC suppresses the nucleotidyltransferase activity (PubMed:26440888).
CC Phosphorylation at Ser-420 promotes the cyclic GMP-AMP synthase
CC activity (PubMed:32474700). Phosphorylation at Thr-52 and Ser-199
CC inhibits its cyclic GMP-AMP synthase activity (By similarity).
CC Ubiquitination at Lys-372 via 'Lys-27'-linked polyubiquitination
CC enhances the cyclic GMP-AMP synthase activity (By similarity).
CC Monoubiquitination at Lys-335 promotes oligomerization and subsequent
CC activation (PubMed:29426904). Sumoylation at Lys-335, Lys-372 and Lys-
CC 382 prevents DNA-binding, oligomerization and nucleotidyltransferase
CC activity (PubMed:28095500). The enzyme activity is impaired by the
CC cleavage by CASP1 (PubMed:28314590). In addition to DNA, also activated
CC by collided ribosomes upon translation stress: specifically binds
CC collided ribosomes, promoting its activation and triggering type-I
CC interferon production (By similarity). In hematopoietic stem cells,
CC binding to circular RNA cia-cGAS inhibits the cyclic GMP-AMP synthase
CC activity (PubMed:29625897). Strongly inhibited by compound RU.521,
CC which is specific for mouse protein (PubMed:28963528, PubMed:30007416).

CC nucleosomes; interaction is mainly mediated via histones H2A and H2B
CC and inactivates the nucleotidyltransferase activity by blocking DNA-
CC binding and subsequent activation (PubMed:32911481, PubMed:32911480,

CC Interacts with TRIM14; this interaction recruits USP14, leading to
CC deubiquitinate and stabilize CGAS and promote type I interferon
CC production (By similarity). Interacts with ZCCHC3; promoting sensing of

CC ECO:0000269|PubMed:28314590, ECO:0000269|PubMed:30878284}.
CC -!- SIMILARITY: Belongs to the mab-21 family. {ECO:0000305}.
CC -!- CAUTION: Was reported to homodimerize in presence of double-stranded
CC DNA (dsDNA) (PubMed:24332030). However, this result was based on a
CC structure lacking the N-terminal part (1-146), which caused
CC homodimerization in presence of dsDNA (PubMed:28214358).
CC {ECO:0000269|PubMed:24332030}.
