    Snippet: The coronavirus (CoV) N protein oligomerizes via its carboxyl terminus. However, the oligomerization mechanism of the C-terminal domains (CTD) of CoV N proteins remains unclear. Based on the protein disorder prediction system, a comprehensive series of HCoV-229E N protein mutants with truncated CTD was generated and systematically investigated by biophysical and biochemical analyses to clarify the role of the C-terminal tail of the HCoV-229E N protein in oligomerization.

    Document: The coronavirus (CoV) N protein oligomerizes via its carboxyl terminus. However, the oligomerization mechanism of the C-terminal domains (CTD) of CoV N proteins remains unclear. Based on the protein disorder prediction system, a comprehensive series of HCoV-229E N protein mutants with truncated CTD was generated and systematically investigated by biophysical and biochemical analyses to clarify the role of the C-terminal tail of the HCoV-229E N protein in oligomerization. These results indicate that the last C-terminal tail plays an important role in dimer–dimer association. The C-terminal tail peptide is able to interfere with the oligomerization of the CTD of HCoV-229E N protein and performs the inhibitory effect on viral titre of HCoV-229E. This study may assist the development of anti-viral drugs against HCoV.
