STING is primarily located in ER and traffics to Golgi/lysosome upon activation.[16] Using confocal imaging, we observed that a fraction of STING co‐localized with MitoView as a mitochondria marker in A498 tumor cells (Figure 3J), and STING was detected in purified mitochondrial fractions (Figure 3K). Here, STING1 is linked to neoplasm.
