Background Information

TMEM173, also named as ERIS, MITA, STING and MPYS, is a facilitator of innate immune signaling that promotes the production of type I IFN (IFN-alpha and IFN-beta). TMEM173 mediates death signaling via activation of the extracellular signal-regulated kinase (ERK) pathway. There're monomer (35-40 kDa)(PMID: 27324217; 29632140;30918080) and dimer (80 kDa) form of TMEM173 in western blot test.
