Background: STING/TMEM173

STING (stimulator of interferon genes) is encoded by the TMEM173 gene and is an adaptor molecule involved in the activation of innate immune responses to PAMPS (pathogen-associated molecular patterns) and DAMPS (damage-associated molecular patterns). STING specifically recognizes cytosolic DNA products derived from pathogens (e.g., cytomegalovirus, vaccinia virus, Listeria monocytogenes) or dead cells (1, 2). In the STING pathway, dsDNA derived from pathogens or damaged cells serves as a substrate for the enzyme cGAS (cyclic GMP-AMP synthase) which produces the second messenger cyclic GMP-AMP (cGAMP) from ATP and GTP (3, 4). Under steady-state conditions STING (theoretical molecular weight 42 kDa), a protein localizes to the ER membrane. Upon activation by dsDNA derived second messenger (cGAMP), STING translocates to the Golgi apparatus as a homodimer. Once STING has trafficked to the perinuclear region, it activates TANK binding kinase 1 (TBK1), interferon regulatory factor 3 (IRF3) and NF-kB leading to the production of cytokines (e.g., type I interferon) (2, 4). Mutations in the TMEM173 gene affecting STING expression are associated with the development of the auto-inflammatory disease SAVI (STING-associated vasculopathy with onset in infancy) (2). A novel SAVI dominant mutation in the TMEM173 human gene (V155M) leads to increased localization of STING to the Golgi and perinuclear region, indicative of an activated state (1). Hallmarks of SAVI, a rare inflammatory disease, include severe vasculitis in extremities and lung inflammation (7).
