[https://www.uniprot.org/uniprot/STING_NEMVE STING_NEMVE] Sensor of cytosolic DNA from bacteria and viruses that promotes autophagy (PubMed:30842662). Acts by recognizing and binding cyclic GMP-AMP (cGAMP), a messenger produced by CGAS in response to DNA in the cytosol (PubMed:26300263, PubMed:30842662). Following cGAMP-binding, promotes the formation of autophagosomes, leading to target cytosolic DNA for degradation by the lysosome (PubMed:30842662). Exhibits guanine base-specific ligand recognition. Binds 3'-3'linked cGAMP, 2'-3' linked cGAMP and 3'-3' linked c-di-GMP with much greater affinity as compared to 3'-3' linked c-di-AMP (PubMed:26300263). Lacks the C-terminal tail (CTT) found in mammalian orthologs which is essential for interferon signaling (PubMed:26300263).<ref>PMID:26300263</ref> <ref>PMID:30842662</ref>

In humans, the cGAS-STING immunity pathway signals in response to cytosolic DNA via 2',3' cGAMP, a cyclic dinucleotide (CDN) second messenger containing mixed 2'-5' and 3'-5' phosphodiester bonds. Prokaryotes also produce CDNs, but these are exclusively 3' linked, and thus the evolutionary origins of human 2',3' cGAMP signaling are unknown. Here we illuminate the ancient origins of human cGAMP signaling by discovery of a functional cGAS-STING pathway in Nematostella vectensis, an anemone species &gt;500 million years diverged from humans. Anemone cGAS appears to produce a 3',3' CDN that anemone STING recognizes through nucleobase-specific contacts not observed in human STING. Nevertheless, anemone STING binds mixed-linkage 2',3' cGAMP indistinguishably from human STING, trapping a unique structural conformation not induced by 3',3' CDNs. These results reveal that human mixed-linkage cGAMP achieves universal signaling by exploiting a deeply conserved STING conformational intermediate, providing critical insight for therapeutic targeting of the STING pathway.
