Nsp1 and Nsp2 interactome and proteome


ABSTRACT: The samples represent pulldowns of protein Nsp1 and Nsp2 from SARS-CoV and SARS-CoV2, as well its unfunctional mutants. Additionally, total proteomes of corresponding samples were analyzed.

SARS-CoV-2, responsible for the ongoing global pandemic, must overcome a conundrum faced by all viruses. To achieve its own replication and spread, it simultaneously depends on and subverts cellular mechanisms. At the early stage of infection, SARS-CoV-2 expresses the viral nonstructural protein 1 (NSP1), which inhibits host translation by blocking the mRNA entry tunnel on the ribosome; this interferes with the binding of cellular mRNAs to the ribosome. Viral mRNAs, on the other hand, overcome t  ...[more]
