The nsp3 Macrodomain Promotes Virulence in Mice with Coronavirus-Induced Encephalitis

Abstract excerpt

UNLABELLED: All coronaviruses encode a macrodomain containing ADP-ribose-1"-phosphatase (ADRP) activity within the N terminus of nonstructural protein 3 (nsp3). Previous work showed that mouse hepatitis virus strain A59 (MHV-A59) with a mutated catalytic site (N1348A) replicated similarly to wild-type virus but was unable to cause acute hepatitis in mice. To determine whether this attenuated phenotype is...
