Chromatin-tethering approach

WebApr 30, 2024 · The nuclear envelope not only serves as a physical barrier separating nuclear content from the cytoplasm but also plays critical roles in modulating the three-dimensional organization of genomic DNA. For both plants and animals, the nuclear periphery is a functional compartment enriched with heterochromatin. To date, how … WebFeb 4, 2024 · Here, we present direct evidence that cGAS activity is suppressed during mitosis through two mechanisms, hyperphosphorylation at the N terminus and inhibition of oligomerization due to chromatin tethering. Both mechanisms prevent cGAS phase separation into liquid droplets where cGAS can efficiently synthesize cGAMP.
