How does SARS-CoV-2 N protein phase separation specifically disrupt cGAS-G3BP1 assembly at the molecular level?

OPEN

The abstract shows N protein undergoes LLPS to disrupt cGAS-G3BP1 complex formation, but the precise molecular mechanisms of this disruption remain unclear. Understanding these mechanisms could reveal therapeutic targets for preserving innate immunity during viral infection. Gap type: unexplained_observation Source paper: Phase-separated nucleocapsid protein of SARS-CoV-2 suppresses cGAS-DNA recognition by disrupting cGAS-G3BP1 complex. (2023, Signal transduction and targeted therapy, PMID:37100798)
