claim: nsp1 of sars-cov-2 stimulates host immunity termination
evidence_1: considering the presence of nsp1 in the post- termination 80s ribosomal complex simultaneously with erf1, we hypothesized that nsp1 may be involved in translation termination.", "we show the direct influence of nsp1 on translation termination.", "we identify that activity of nsp1 in translation termination is localized in its n-terminal domain.", "nsp1 inhibits host translation initiation by binding to the entry channel of the 40s ribosome subunit.")
