cGAS Enzyme Has an Important Role in the STING Pathway

When free DNA is in the cytoplasm of eukaryotic cells, it can be an indication of damage or infection to the cell. This DNA triggers an immune response led by type I interferon (IFN) production. The cGAS enzyme acts as a unique sensor for double-stranded DNA. When DNA binds to cGAS it activates the enzyme producing a dinucleotide cGAMP from ATP and GTP. cGAMP created by cGAS activates STING (stimulator of interferon genes), leading to IFN immune response in the cell.
