In the past decade, membraneless assemblies known as biomolecular condensates have been reported to play key roles in many cellular functions by compartmentalizing specific proteins and nucleic acids subcellular environments with distinct properties. Furthermore, growing evidence supports view that often form phase separation, which a single-phase system demixes into two-phase consisting of condensed dilute particular biomolecules. Emerging understanding condensate function normal aberrant states, mechanisms formation, is providing new insights human disease revealing novel therapeutic opportunities. this Perspective, we propose such could enable previously unexplored drug discovery approach based on identifying condensate-modifying therapeutics (c-mods), discuss strategies, techniques challenges involved.

Abstract Viruses, as opportunistic intracellular parasites, hijack the cellular machinery of host cells to support their survival and propagation. Numerous viral proteins are subjected host-mediated post-translational modifications. Here, we demonstrate that SARS-CoV-2 nucleocapsid protein (SARS2-NP) is SUMOylated on lysine 65 residue, which efficiently mediates SARS2-NP’s ability in homo-oligomerization, RNA association, liquid-liquid phase separation (LLPS). Thereby innate antiviral immune response suppressed robustly. These roles can be achieved through intermolecular association between SUMO conjugation a newly identified SUMO-interacting motif SARS2-NP. Importantly, widespread SARS2-NP R203K mutation gains novel site SUMOylation further increases LLPS immunosuppression. Notably, E3 ligase TRIM28 responsible for catalyzing SUMOylation. An interfering peptide targeting interaction was screened out block LLPS, consequently inhibit replication rescue immunity. Collectively, these data critical virulence, therefore provide strategy antagonize SARS-CoV-2.
