The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Nsp1 C-terminal domain was shown to bind the ...Nonstructural protein 1 (Nsp1) produced by coronaviruses inhibits host protein synthesis. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Nsp1 C-terminal domain was shown to bind the ribosomal mRNA channel to inhibit translation, but it is unclear whether this mechanism is broadly used by coronaviruses, whether the Nsp1 N-terminal domain binds the ribosome, or how Nsp1 allows viral RNAs to be translated. Here, we investigated Nsp1 from SARS-CoV-2, Middle East respiratory syndrome coronavirus (MERS-CoV), and Bat-Hp-CoV coronaviruses using structural, biophysical, and biochemical experiments, revealing a conserved role for the C-terminal domain. Additionally, the N-terminal domain of Bat-Hp-CoV Nsp1 binds to the decoding center of the 40S subunit, where it would prevent mRNA and eIF1A accommodation. Structure-based experiments demonstrated the importance of decoding center interactions in all three coronaviruses and showed that the same regions of Nsp1 are necessary for the selective translation of viral RNAs. Our results provide a mechanistic framework to understand how Nsp1 controls preferential translation of viral RNAs.

In the structure databanks used in Yorodumi, some data are registered as the other names, "COVID-19 virus" and "2019-nCoV". Here are the details of the virus and the list of structure data.

EMDB accession codes are about to change! (news from PDBe EMDB page)
The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
The EM Navigator/Yorodumi systems omit the EMD- prefix.

Yorodumi is a browser for structure data from EMDB, PDB, SASBDB, etc.
This page is also the successor to EM Navigator detail page, and also detail information page/front-end page for Omokage search.
The word "yorodu" (or yorozu) is an old Japanese word meaning "ten thousand". "mi" (miru) is to see.
