WebOct 28, 2024 · cytoplasmic chromatin fragment mitochondrial DNA retrotransposon senescence cancer aging Introduction DNA, in its function as the primary medium for storage of biological information, resides in specialized compartments, separate from the rest of the eukaryotic cell. WebcGMP-AMP (cGAMP) synthase (cGAS) is a cytosolic DNA sensor that is activated by binding to double-stranded DNA, including microbial and self-DNA (22, 23).Cytosolic DNA triggers cGAS to produce the second messenger cGAMP (), which binds and activates the adaptor protein STING (also known as MITA, MPYS, and TMEM173).STING then …
