A research team at Ruhr University Bochum, Germany, has identified a previously unknown cellular mechanism crucial to the replication of coronaviruses: c-Jun N-terminal kinase (JNK) is activated during infection with human coronavirus HCoV-229E and mediates the phosphorylation of the viral nucleocapsid (N) protein, an integral step in the virus cycle. These results aid in better understanding virus-host interactions and may open new approaches to exploring antiviral strategies in the long term.
