Background
TMEM173 (STING, Stimulator of interferon genes) is endoplasmic-reticulum-resident transmembrane adaptor serving as central hub of cGAS-STING innate-immunity pathway for cytosolic-DNA-sensing signal transduction. Cytosolic-DNA-activated cGAS generates second-messenger cGAMP, which binds ER-localized STING and triggers STING oligomerization and Golgi translocation. STING recruits and activates TBK1 kinase to phosphorylate IRF3 and NF-κB, inducing type-I-interferon and pro-inflammatory-cytokine production to initiate antiviral and anti-tumor immune responses. Loss-of-function STING mutations impair cytosolic-DNA immune surveillance, while aberrant STING activation drives auto-inflammatory disorders.
