Endogenous STAT6 was found to co-fractionate with STING from the lysates of Herpes simplex virus 1 (HSV-1) - infected HeLa cells. Similar results were obtained from Sendai virus (SeV)-infected HeLa cells, where STAT6 redistributed to the perinuclear region to co-localizes with STING upon infection. Co-immunoprecipitation assays confirmed STAT6-STING interaction in human embryonic kidney HEK293 cells. The DNA-binding domain (DBD) of STAT6 and C terminus (aa 317-379) of STING were essential for this interaction. The TBK1 kinase activity was required for virus-induced STAT6 phosphorylation, however the direct interaction between STAT6 and TBK1 is not yet reported (Chen H et al. 2011). Co-immunoprecipitation assays in HEK293T cells expressing HA-tagged STING and Flag-tagged TBK1 showed that TBK directly interacts with STING (Ouyang S et al. 2012).
