cGAS

A type-I interferon response is triggered by the cytosolic DNA sensor cyclic GMP-AMP synthase (cGAS). When self or microbial DNA enters the cytoplasm, cGAS binds to it and catalyzes the synthesis of cGAMP. The production of type-I IFNs is then triggered by cGAMP acting as a second messenger that binds to and activates the endoplasmic reticulum protein STING. STING attracts TBK1, which phosphorylates substrates like IKK, cRel, and p62 as well as transcription factors like IRF3/7.

In Huntington disease (HD), cGAS plays a crucial role in controlling inflammatory and autophagic responses. Age-related macular degeneration and cellular senescence are two conditions that cGAS can significantly affect by inducing signaling that is known to promote the up-regulation of inflammatory genes. This shows that there is a strong molecular and signaling connection between the inflammatory response and autophagy.cGAS also plays a significant role in the regulation of autophagy.
