SARS-CoV-2 and human cold coronavirus OC43 inhibit stress granule formation through Nsp15 protein

In a recent study published in the journal PLOS pathogensresearchers investigated the mechanisms through which the human common cold Betacoronavirus OC43 (HCoV-OC43) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) inhibit the formation of stress granules. Study: Nsp1 proteins of human coronaviruses HCoV-OC43 and SARS-CoV2 inhibit stress granule formation. Image Credit: MIA Studio/Shutterstock Background Stress … Read more

Research reveals the assembly dynamics of nucleocapsid protein condensates can be regulated by small molecules with therapeutic potential

In a recent study posted to bioRxiv*, researchers developed a screening platform and identified molecules with anti-coronavirus (anti-CoV) activity. Study: A screen for modulation of nucleocapsid protein condensation identifies small molecules with anti-coronavirus activity. Image Credit: jijomathaidesigners/Shutterstock Background Biomolecular condensates are membrane-less organelles formed by liquid-liquid phase separation of proteins or ribonucleic acids (RNAs). The … Read more

New chemical probe can selectively inhibit human COQ8A protein in cells

Inhibition of the COQ8 protein could be beneficial in the treatment of diseases such as cancer. CoQ8 is needed for the biosynthesis of coenzyme Q, also known as ubiquinone. A new collaborative study from the University of Eastern Finland, Washington University in St. Louis, University of Wisconsin-Madison, University of North Carolina at Chapel Hill and … Read more
