Stress granules (SGs) are dynamic, membraneless ribonucleoprotein condensates that assemble in response to cellular stress and coordinate diverse cellular stress responses and diseases. Although SG have been reported to associate with the endoplasmic reticulum (ER), how ER-localized stress granule assembly is organized and regulated remains unclear. STING (stimulator of interferon genes) is a central innate immune adaptor that has recently been implicated in diverse non-canonical cellular functi...
