Kobe University researchers discover an enzyme in SARS-CoV-2 that removes ISG15, evading immune defenses and increasing infectivity.

Researchers at Kobe University have identified an enzyme in SARS-CoV-2 that allows the virus to evade the body's innate immune defenses, which may explain its higher infectivity compared to previous coronaviruses like SARS and MERS. This enzyme removes a molecular tag, ISG15, from the virus's nucleocapsid, facilitating virus assembly. The findings could inform the development of more effective antiviral drugs targeting this mechanism.
