Target Information

SARS-CoV-2 nsp1 inhibits host translation by interacting with the 40S ribosomal subunit (PubMed:32680882).
The C-terminus of nsp1 binds to and obstructs the ribosomal mRNA entry tunnel, thereby inhibiting antiviral responses triggered by innate immunity or interferons.
The nsp1–40S ribosome complex induces endonucleolytic cleavage near the 5′UTR of host mRNAs, leading to their degradation.
Viral mRNAs are protected from this cleavage due to the presence of a 5′-end leader sequence.
By suppressing host gene expression, nsp1 facilitates efficient viral gene expression and evasion from host immune response.
