    basic FUNCTION
  • is a cytosolic DNA sensor that induces interferons by producing the second messenger cGAMP
  • is a cytosolic dsDNA sensor mediating the innate immunity to microbial DNA
  • is a vital innate immune sensor of M. tuberculosis infection
  • CGAS is a cytosolic DNA sensor that activates the IFN pathway
  • is an essential DNA virus sensor that triggers type I interferon (IFN) signaling by producing cGAMP to initiate antiviral immunity
  • role of CGAS in the innate immune responses against pathogenic DNAs
  • is a DNA-sensing enzyme in the innate immune system
  • mediates innate immune responses against invading pathogens, or against self-dsDNA, which causes autoimmune disorders
  • CGAS restoration or TMEM173 stimulation by small molecules during infancy might improve the age-dependent susceptibility to DNA virus infection
  • CGAS recognizes cytosolic chromatin fragments in senescent cellsand the activation of CGAS, in turn, triggers the production of senescence-associated secretory phenotype (SASP) factors via TMEM173, thereby promoting paracrine senescence

  • CGAS-induced activation of TMEM173 also involves the activation of the NFKB1 and IRF3 pathways
  • MAVS and TMEM173 transduce signals from the cytosolic nucleic acid sensors DDX58 and CGAS, respectively
  • PQBP1 directly binds to reverse-transcribed HIV-1 DNA and interacts with CGAS to initiate an IRF3-dependent innate respons
  • TRIM14 inhibits CGAS degradation mediated by selective autophagy receptor SQSTM1 to promote innate immune responses
  • SENP7 interacted with and potentiated CGAS activation
  • unique innate immune activation cascade in which TBK1-IKBKB formed a positive feedback loop to assure robust cytokine production during CGAS-TMEM173 activation
  • loss of the CGAS-TMEM173 pathway may be required to evade Extrachromosomal telomere repeat (ECTR)-induced anti-proliferation effects and permit alternative lengthening of telomeres (ALT) development in cancer
