Severe acute respiratory syndrome (SARS) is a respiratory disease, caused by a
coronavirus (SARS-CoV), that is characterized by atypical pneumonia. The
nucleocapsid protein (N protein) of SARS-CoV plays an important role in
inhibition of type I interferon (IFN) production via an unknown mechanism. In
this study, the SARS-CoV N protein was found to bind to the SPRY domain of the
tripartite motif protein 25 (TRIM25) E3 ubiquitin ligase, thereby interfering
with the association between TRIM25 and retinoic acid-inducible gene I (RIG-I)
and inhibiting TRIM25-mediated RIG-I ubiquitination and activation. Type I IFN
production induced by poly I·C or Sendai virus (SeV) was suppressed by the
SARS-CoV N protein. SARS-CoV replication was increased by overexpression of the
full-length N protein but not N amino acids 1 to 361, which could not interact
with TRIM25. These findings provide an insightful interpretation of the
SARS-CoV-mediated host innate immune suppression caused by the N
protein.IMPORTANCE The SARS-CoV N protein is essential for the viral life cycle
and plays a key role in the virus-host interaction. We demonstrated that the
interaction between the C terminus of the N protein and the SPRY domain of TRIM25
inhibited TRIM25-mediated RIG-I ubiquitination, which resulted in the inhibition
of IFN production. We also found that the Middle East respiratory syndrome CoV
(MERS-CoV) N protein interacted with TRIM25 and inhibited RIG-I signaling. The
outcomes of these findings indicate the function of the coronavirus N protein in
modulating the host's initial innate immune response.
